Published: June 2019

<p>The understanding of knowledge transfer and information delivery is recently in the broader scope due to the development of educational technology. The information delivery is not merely done using verbal message; however, multiple modes of presentation such as verbal and auditory representation can also be the alternative of material delivery. The studies featuring the use of multimedia-based presentation are mostly administered to determine its effectiveness to be implemented in the learning process. In contrast, the exploration of the use of multimedia-based presentation toward the way how it can be a means of interaction seems underexplored. Therefore, to make it be more precise, the present study attempts to explore the practice of multimedia-based presentation in academic speaking classroom and to investigate the interactivity emerged during the presentation process. This study deployed qualitative case study design due to the purpose of gaining the in-depth investigation of the use of multimedia-based presentation and its interactivity emergence in academic speaking classroom. The study was conducted in one of the universities in Surakarta majoring English Education where academic speaking becomes one of the subjects. The presentation document along with the presentation process were analyzed in this study. The results of the analysis show that multimedia-based presentation is designed to visualize the material being conveyed through the icons, pictures, and illustrations that are able to represent the information or knowledge in a more concrete way. Moreover, the interactivity is also emerged through the use of multimedia-based presentation as it simplifies the presenter to do the following: gesturing, dialoguing, and describing. The results implies the opportunity for both teachers and academic speaking presenters to innovate how they present the material by using multimedia-based presentation. In practice, multimedia-based presentation along with its interactivity can clarify the materials, grab the audience attention, and stimulate the audience responses.</p>

Published: June 2019

Prospective English teachers found that selecting or designing instructional materials and media was burdensome due to their lack experiences. They need to enroll in a systematic learning model to develop relevant instructional materials and media. Project-based learning has been an effective learning model to develop students’ skills in a specific content area. The nature of project-based learning to enable students acquire knowledge and give ample experiences in a reflective way supported English prospective teachers in instructional materials and media development (IMALD) classrooms to learn how to design materials and multimedia-based media for their future pupils. A case study was employed to investigate the implementation of project-based learning in instructional materials and media development classrooms. The stages involved in this study are, namely: 1) identifying the phenomenon, 2) identifying the research participants, 3) generating hypotheses, 4) collecting data, 5) analyzing data, and 6) interpreting data. Thirty five students were assigned to participate in this research and develop textbook as well as supplementary multimedia-based media following the steps in project-based learning comprising planning to develop textbook and multimedia-based media, monitoring, scaffolding, adjusting or troubleshooting strategies, assessing students and evaluating projects. The result of this study was the final product in the form of textbook and multimedia-based media to teach English for students in elementary school, junior high school and senior high school. Moreover, project-based learning made students in IMALD classrooms became more contented and motivated in designing instructional materials and media for teaching and learning purposes by integrating their knowledge of materials development and computer software application.

Abstract
Background: Species of Zanthoxylum (Sichuan pepper) are diverse and valuable economic trees that have been cultivated across Asia for thousands of years for their aromatic and medicinal properties. The current lack of transcriptome and EST-SSR data for these species represents a constraint with regards to identifying increasingly more diverse cultivars in China. This study was conducted to compare the transcriptome profiles of two Zanthoxylum species (Z. bungeanum and Z. armatum) and develop the EST-SSR markers to assess the genetic diversity in Sichuan pepper.
Results: A total of 36.76 G high-quality clean data were screened for subsequent analysis. For Z. bungeanum and Z. armatum, 64,944 and 75,669 unigenes were obtained, respectively. After comparing different databases, we found that the highest number of unigenes (43,3198 and 49,638 for Z. bungeanum and Z. armatum, respectively) were annotated using the NR database. In addition, six pairs of EST-SSR markers were selected to determine the genetic diversity of 125 samples of three Zanthoxylum species. A population clustering dendrogram indicated that there was an average of four samples per population, with the number of allelic genes (Na) ranging from 1 to 1.4510 (average of 1.1462). The number of effective allelic genes (Ne) ranged from 1 to 1.2744 (average of 1.0971),
whereas genetic diversity (Nei) ranged from 0 to 0.1486 (average of 0.05512) and Shannon genetic diversity (I) ranged from 0 to 0.2177 (average 0.08123). In individual clustering dendrograms, the 125 samples were divided into five cohorts. Cohort I contained Z. bungeanum and its varieties, cohort II included Z. armatum and its varieties, cohort III contained mostly Z. piperitum and two other Z. bungeanum samples, and cohorts IV and V each contained only two samples, with genetic distances of 0 to 1.14 between them.
Conclusion: In this study, we analyzed the comparative transcriptome data of two Zanthoxylum species, for which we assessed genetic diversity using EST-SSR primers derived from their EST information. The genetic diversity of 125 samples obtained from the three Zanthoxylum species Z. bungeanum, Z. armatum and Z. piperitum was relatively low, which can probably be attributed to apomixis.

Abstract
Background

Calibration algorithms applied to the Youth Activity Profile (YAP) self-report questionnaire in the US have accurately estimated moderate-to-vigorous physical activity (MVPA) and sedentary behaviour (SB). However, the efficacy of the calibration algorithms may vary when applied to different populations. We aimed to: (1) assess the accuracy of US-generated YAP calibration algorithms for MVPA and SB with English youth, (2) validate English-specific YAP calibration algorithms, (3) examine their potential surveillance utility to assess compliance to MVPA guidelines.

Methods

Four primary schools and five secondary schools were recruited. Four-hundred-and-two participants (aged 9-16 years; 212 boys) wore SenseWear Armband Mini devices (SWA) for eight days and completed the YAP on the eighth day. For aim (1) the original US calibration algorithms were applied to the YAP scores, which were matched to SWA-estimated in-school, out-of-school, and weekend MVPA and out-of-school SB data. For aim (2) new calibration algorithms for the equivalent time-segments were generated from the English YAP data using quantile regression. The algorithms were applied in an independent cross-validation sample, and individual- and group-level agreement were assessed using bias, mean absolute percent error (MAPE) and equivalency tests, respectively. For aim (3) the utility of the English YAP algorithms to assess compliance to MVPA guidelines was examined using kappa, sensitivity, and specificity.

Results

Agreement between the US calibration algorithms and SWA estimates of MVPA and SB was poor. Group-level MAPE for the English YAP-estimates of in-school, out-of-school, and weekend MVPA ranged from 3.6% to 17.3%. Bias for these estimates were 17.2 (34.4), 31.6 (14.0), and -4.9 (3.6) min·week-1, respectively. Out-of-school SB was over-predicted by 109.2 (11.8) min·week-1 (MAPE=11.8%). Predicted YAP values were within 15%-20% equivalence of the SWA estimates. Classification accuracy of the English YAP MVPA estimates for compliance to 60 min·day-1 and 30 min·school-day-1 MVPA recommendations were 91%/37% and 89%/57% sensitivity/specificity, respectively.

Conclusions

The English YAP generated robust group-level estimates of MVPA and SB and has potential for surveillance to monitor compliance with MVPA guidelines. The YAP’s accuracy may be further improved through research work with more representative UK samples to enhance the calibration process and to refine the resultant algorithms.
The association between sedentary behaviour and indicators of stress: A systematic review
Authors: Teychenne Megan , Stephens Lena D , Costigan Sarah A , Olstad Dana Lee , Stubbs Brendon , Turner Anne I 
Published: June 2019

Abstract
Background

Emerging evidence shows sedentary behaviour may be associated with mental health outcomes (e.g. anxiety, depression). Yet, the strength of the evidence linking sedentary behaviour and stress is unclear. This study aimed to synthesise evidence regarding associations between time spent in sedentary behaviour and stress in adults.

Methods

A systematic search was conducted (January 1990 – November 2018). Following PRISMA guidelines, an evaluation of methodological quality, and best-evidence synthesis of associations between time in sedentary behaviour (including sitting time, TV viewing, computer use) and stress were presented. Twenty-three studies reporting on data from n=68,932 people (age 18-98y, 62.7% women) were included.

Results

Across the studies (n=2 strong-, n=7 moderate- and n=14 weak-quality), there was insufficient evidence that overall time in sedentary behaviour and sitting time were associated with stress, regardless of the type of measure used (objective or subjective) to assess sedentary behaviour or stress. There was strong evidence of no association between TV viewing, or computer use and stress.

Conclusion

Although previous research may suggest sedentary behaviour may be linked to mental health outcomes such as depression and anxiety, the evidence for an association between various types of sedentary behaviour and stress is limited in quality, and relationships are either inconsistent or null. High-quality longitudinal/interventional research is required to confirm findings and determine the direction of associations between different contexts (i.e. purpose) and domains (i.e. leisure, occupational, transport) of sedentary behaviour and stress.
Round hole, square peg: social inequalities and the political legitimization of health technology in Norway, a critical discourse analysis
Authors: Weiss Daniel 
Published: June 2019

Abstract
Background: Although technological innovations in health have proven effective, their uncritical development and adoption leaves little room for understanding consequences that may undermine their aggregate social value. As research is increasingly understanding the impacts these technologies are having on social inequalities, political discourse is often a force promoting their development and adoption. This study therefore aimed to investigate national public health policy discourse with specific focus on innovative health technology and social inequalities – in a Norwegian context. Methods: The analysis relies on a perspective grounded in critical discourse analysis (CDA), with inspiration from a discourse-historical approach (DHA) and political discourse analysis. Included in the analysis are central documents typically influential in the lawmaking procedure. Documents were coded and analyzed using Nvivo and supported by summary notes. Results: The results and discussion focus on three major discourse strands: the “technologies discourse” (types of technologies), the “responsibility discourse” (who has responsibility for health and technology), and the “legitimization discourse” (the ways in which these technologies are legitimized). Conclusion: In conclusion, we find that despite an overt political imperative for reducing social inequalities in health, the Norwegian health technologies discourse gives little attention to the potential for these innovations to unintentionally (re)produce social inequalities. Instead, the discourse is characterized by neoliberal undertones that individualize and commercialize public health and promote a pro-innovation ideology.
Determining ‘Curriculum Viability’ through Standards and Inhibitors of Curriculum Quality: A Scoping Review
Authors: Khan Rehan Ahmed , Spruijt Annemarie , Mahboob Usman , Merrienboer Jeroen J. G. van 
Published: June 2019

Abstract
Background

A curriculum is dynamic entity and hence, metaphorically, can be considered ‘alive’. Curricular diseases may impair its quality and hence its viability. The quality of a curriculum is typically assessed against certain quality standards only. This approach does not identify the inhibitors impeding the achievement of quality standards. The purpose of this study is to identify not only standards but also inhibitors of curriculum quality, allowing for a more comprehensive assessment of what we coin ‘curriculum viability’.

Methods

We performed a scoping review of ‘curriculum viability’, after which 13 articles were found eligible through a meticulous search and selection process. We first identified 1233 studies based on matching keywords, title and abstract; 36 of which met our inclusion criteria. After application of the Qualsyst criteria, two independent reviewers performed a thematic analysis of the 13 articles that remained.

Results

While all studies reported on standards of quality, only two studies described both standards and inhibitors of quality. These standards and inhibitors were related to educational content and strategy, students, faculty, assessment, educational/work environment, communication, technology and leadership.

Conclusions

The framework of curriculum viability thus developed will help identify inhibitors adversely affecting the curriculum viability and remaining hidden or un-noticed when curriculum evaluation is done.
Analysis of MADS-box genes revealed modified flowering gene network and diurnal expression in pineapple
Authors: Zhang Xiaodan , Fatima Mahpara , Zhou Ping , Ming Ray 
Published: June 2019

Abstract
Background

Pineapple is the most important crop with CAM photosynthesis, but its molecular biology is underexplored. MADS-box genes are crucial transcription factors involving in plant development and several biological processes. However, there is no systematic analysis of MADS-box family genes in pineapple (Ananas comosus).

Results

Forty-eight MADS-box genes were identified in the pineapple genome. Based on the phylogenetic studies, pineapple MADS-box genes can be divided into type I and type II MADS-box genes. Thirty-four pineapple genes were classified as type II MADS-box genes including 32 MIKC-type and 2 Mδ-type, while 14 type I MADS-box genes were further divided into Mα, Mβ and Mγ subgroups. A majority of pineapple MADS-box genes were randomly distributed across 19 chromosomes. RNA-seq expression patterns of MADS-box genes in four different tissues revealed that more genes were highly expressed in flowers and three genes (Aco004785.1, Aco008359.1 and Aco007999.1) were expressed only in flowers. There is no FLC and CO orthologs in pineapple. The loss of FLC and CO orthologs in pineapple indicated that modified flowering genes network in this tropical plant compared with Arabidopsis. The expression patterns of MADS-box genes in photosynthetic and non-photosynthetic leaf tissues indicated the potential roles of some MADS-box genes in pineapple CAM photosynthesis. The 23% of pineapple MADS-box genes showed diurnal rhythm, indicating that these MADS-box genes are regulated by circadian clock.

Conclusions

MADS-box genes identified in pineapple are closely related to flowering development. Some MADS-box genes are involved in CAM photosynthesis and regulated by the circadian clock. These findings will facilitate research on the development of unusual spiral inflorescences on pineapple fruit and CAM photosynthesis.
Quantitative CT parameters correlate with lung function in chronic obstructive pulmonary disease: a systematic review and meta-analysis
Authors: Wang Yan , Lin Shan , Li Jian-Ting , Wu Jing , Han Dong , Guan Wei 
Published: June 2019

Abstract
Background

The aim of the study was to analyze the correlation between quantitative computed tomography (CT) parameters and airflow obstruction in patients with chronic obstruction pulmonary disease (COPD).

Methods

PubMed, Embase, Cochrane and Web of Knowledge were searched by two investigators from inception to 2018, using a combination of pertinent items to discover articles that investigated the relationship between CT measurements and lung function parameters in patients with COPD. Five reviewers independently evaluated the quality, extracted data and evaluated bias. The correlation coefficient was calculated and heterogeneity was explored. The following CT measurements were extracted: percentage of lung attenuation area < -950 Hounsfield Units (HU), mean lung density, percentage of airway wall area, air trapping index, airway wall thickness. Two airflow obstruction parameters were extracted: forced expiratory volume in the first second as a percentage of prediction (FEV1% pred) and FEV1 divided by forced expiratory volume lung capacity.

Results

A total of 117 studies (19,942 participants) were identified, 36 of which (4,762 participants) were suitable for meta-analysis. Results from our analysis demonstrated that there was a significant correlation between quantitative CT parameters and lung function. The absolute pooled correlation coefficients ranged from 0.44 (95% CI, 0.36 to 0.53) to 0.71(95% CI,0.65 to 0.77) for inspiratory CT and 0.59 (95% CI, 0.53 to 0.65) to 0.66 (95% CI,0.61 to 0.72) for expiratory CT.

Conclusions

Results from this analysis demonstrated that quantitative CT parameters are significantly correlated with lung function in patients with COPD. With recent advances in chest CT, we can evaluate morphological features in the lungs that cannot be obtained by other clinical indices, such as pulmonary function tests. Therefore, CT can provide a quantitative method to advance the development and testing of new interventions and therapies for patients with COPD .
Nutritional status of tuberculosis patients, a comparative cross-sectional study
Authors: Feleke Berhanu Elfu , Feleke Teferi Elfu , Biadglegne Fantahun 
Published: June 2019

Abstract
Background

Each year, more than 13.7 million people became an active case of tuberculosis and more than 1.5 million cases of tuberculosis patient will die. The association between tuberculosis and malnutrition is bi-directional, tuberculosis leads the patient to malnutrition, and malnutrition increases the risk of developing active tuberculosis by 6 to 10 times higher. Improving the nutrition of individual greatly reduces tuberculosis. The objectives of this study were to assess the nutritional status and determinants of tuberculosis patients.

Methods

A comparative cross-sectional study design was implemented. The sample size was calculated using Epi-info software. The data were collected from July 2015- May 2018. The data were collected by interviewing method, measuring anthropometrics indicators and collecting the stool and blood samples. The data were entered into the computer using Epi-info software and analyzed using SPSS software. Descriptive statistics were used to identify the proportion of malnutrition. Binary logistic regression was used to identify the determinants of malnutrition.

Results

A total of 5045 study participants were included giving the response rate of 93.1%. The prevalence of underweight among tuberculosis patients was 57.17% (95% CI: 54.80% -59.54%) and 88.52% of tuberculosis patients were anemic. The prevalence of malnutrition (underweight) among tuberculosis free residents was 23.37% (95% CI: 21.93-24.80). The nutritional status of tuberculosis patients were determined by site of infection AOR: 0.68[0.49-0.94], sex of the patient AOR: 0.39 [0.25-0.56], residence AOR: 3.84 [2.74-5.54], intestinal parasite infection AOR: 7 [5.2-9.95], alcohol use disorder AOR: 1.52 [1.17-2.13].

Conclusion

High proportion of tuberculosis patients was malnourished. Tuberculosis patients were highly susceptible to malnutrition and even a very distal factor for malnutrition in the community became a proximal factor for tuberculosis patients.

Published: June 2019

Abstract
Background

The incidence of postoperative pulmonary complications (POPCs) in restrictive pulmonary disorders remains indefinite especially in adults. Therefore, this study is structured to evaluate the incidence and risk factors of POPCs in restrictive pulmonary disorders.

Methods

2177 preoperative consultations have been prospectively evaluated from May 2015 to May 2016 in Cukurova University, Department of Chest Diseases. 60 of them (2.8%) met restrictive pulmonary function tests (PFTs) criteria and all of them were enrolled in the study. Each participant was evaluated at the 7th day and has been followed-up until 30th day after surgery. Clinical, surgical, PFT and arterial blood gas analysis parameters were evaluated to analyse risk factors of POPCs.

Results

The incidence of early and late POPCs as 10% and 11.7% in restrictive pulmonary disorders. Preoperative PaO2 ≤ 68 mmHg is an independent risk factor of POPCs. Surgery site, duration of surgery, age, previous or current smoking, preoperative PFT results, physical status, cardiopulmonary risk points, abnormal chest radiography were not significantly related with an increased risk in our study.

Conclusions

The incidence of POPCs in restrictive pulmonary disorders is high. The patients with restrictive pulmonary disorders should be evaluated with particular care perioperatively. Arterial blood gas analysis may give additional knowledge about increased POPCs risk.
