Introduction: Recently there have been many studies performed on the effectiveness of implementing LEAN principals to improve wait times for emergency departments (EDs), but there have been relatively few studies on implementing these concepts on length of stay (LOS) in the ED. This research aims to explore the initial feasibility of applying the LEAN model to length-of-stay metrics in an ED by identifying areas of non-value added time for patients staying in the ED. Methods: In this project we used a sample of 10,000 ED visits at the Health Science Centre in St. John's over a 1-year period and compared patients’ LOS in the ED on four criteria: day of the week, hour of presentation, whether laboratory tests were ordered, and whether diagnostic imaging was ordered. Two sets of analyses were then performed. First a two-sided Wilcoxon rank-sum test was used to evaluate whether ordering either lab tests or diagnostic imaging affected LOS. Second a generalized linear model (GLM) was created using a 10-fold cross-validation with a LASSO operator to analyze the effect size and significance of each of the four criteria on LOS. Additionally, a post-test analysis of the GLM was performed on a second sample of 10,000 ED visits in the same 1-year period to assess its predictive power and infer the degree to which a patient's LOS is determined by the four criteria. Results: For the Wilcoxon rank-sum test there was no significant difference in LOS for patients who were ordered diagnostic imaging compared to those who were not (p = 0.6998) but there was a statistically significant decrease in LOS for patients who were ordered lab tests compared to those who were not (p = 2.696 x 10-10). When assessing the GLM there were two significant takeaways: ordering lab tests reduced LOS (95% CI = 42.953 - 68.173min reduction), and arriving at the ED on Thursday increased LOS significantly (95% CI = 6.846 – 52.002min increase). Conclusion: This preliminary analysis identified several factors that increased patients’ LOS in the ED, which would be suitable for potential LEAN interventions. The increase in LOS for both patients who are not ordered lab tests and who visit the ED on Thursday warrant further investigation to identify causal factors. Finally, while this analysis revealed several actionable criteria for improving ED LOS the relatively low predictive power of the final GLM in the post-test analysis (R2 = 0.00363) indicates there are more criteria that influence LOS for exploration in future analyses.

AbstractPresent study was aimed at investigating the role of Physical, Environmental, Task, Timing, Learning, Emotion and Perspective (PETTLEP) Imagery technique in the improvement of skill precision level of hockey drag flickers. For this purpose, both male (83) and female (38) hockey drag flickers (n=121) of age ranged between 17 and 27 years were selected from different hockey teams belonging to clubs, colleges, universities, departments, regional and national academies of Pakistan. Participants were made to undergo a Pretest-Intervention-Posttest research design consisted of 20 drag flicks and filling of SIAQ questionnaire. Drag Flick Precision Measurement Test (DFPMT) along with Sports Imagery Ability Questionnaire (SIAQ) were used to measure their skill precision levels and their imagery ability. The participants were classified into three categories as per their skill precision levels (Point-based), ranging from 48 Novice (upto12 points), 42 Intermediate (13–18 points) and 31 Elite (19 points and above), and were randomly assigned to one of four intervention groups; Physical Practice (PP), PETTLEP Imagery Practice (IP), Physical Practice+PETTLEP Imagery Practice Combination (CP), and No Practice (NP) Control group. Each group performed their respective tasks for 10 weeks through specially designed physical training programs aided by Imagery scripts. Paired sample t test analysis showed that all groups improved significantly (p<0.05) from pre- to post-test, and the CP group improved more with average improvement value of 8.32 for DFPMT and 5.39 for SIAQ (p<0.05) than the IP, PP and NP groups. However, there was no significant difference found between the PP (Sig. 0.73) and NP (Sig. 0.44) groups in SIAQ. Result extend prior research findings and suggests that PETTLEP Imagery practice used in combination with Physical practice has substantial impact on improving performance of complex motor skills, Present findings showed that PETTLEP imagery model was found to improve player’s precision skill levels, especially when it was combined with physical practice. However, further studies in this connection are needed.

This study aimed to investigate the effect of using news as authentic materials for essay writing skills. This experimental study employed the one-group pre-test and post-test design to 18  fourth-semester students who joined the Essay Writing Course in one of the universities in Indonesia. These students were selected through systematic random sampling and went through treatments for 12 meetings where they were taught in a hybrid learning setting. The first four meetings used the conventional face-to-face classroom interaction. The rest of the meetings were done online because of the outbreak of COVID 19. The instruments to collect data were tests and documentation. Before they were given to the students, the teaching materials, pre-test, and post-test designs were tested and validated. The authentic materials were news texts about global issues such as poverty, environmental protection, gender, race and ethnicities, and diseases. Two raters scored the students’ writing by using Jacobs ESL Composition Profile. The researchers used IBM SPSS 25 software to analyze the data. The results of a paired sample t-test analysis showed that there was no significant difference in the students’ writing scores before and after using news as authentic materials (p = .959 α = 0.05). The paper further discusses the implications of this study for theoretical and practical use.

ABSTRACT. RRRV (Reading, Retelling, Rehearsal, and Videotaping) learning method is a verbal English learning method which is useful to combine reading ability and retelling a story preceeded by doing rehearsal and therefore students’ verbal competence can be increased during this process. This research aims to test the effectiveness in applying RRRV to merely RRR without V. The subjects are students at faculty of language and literature consisting of group A (RRRV) and group B (RRR) only. Pre-test of English proficiency is given to group A and group B before treatment is presented to both of them. The result of the test is used to ascertain whether the goups are homogenous in terms of their English proficiency. It shows that both group A and B have equal ability in TOEFL test result, thus both groups are considered to be homogenous and hence different treatment are given to group A and B. After treatments, data is taken from both groups based on post-test result by retelling the content of story and including video-taping for group A and audio-taping for group B. Meanwhile, data is taken from questionnaire consists of students’ opinion in applying RRRV and RRR method. Data from the test is stored in SPSS version 22 and inferential statistics of independent sample t-test analysis is used to examine if there is significant difference between the use of RRRV and RRR only. The result of questionnaire is analysed using descriptive statistics. Hopefully, the resulf of this research is able to contribute to the body of knowledge about how to improve verbal English proficiency. Keywords: RRRV, RRR, verbal English proficiency

Context: First aid is an emergency measure of saving a life, preventing further deterioration, and promoting recovery of the victim before professional medical help is initiated.  Awareness campaigns are significant community efforts to raise awareness of community groups regarding critical concerns. Aim: The aim of this study is to evaluate the effect of the first aid awareness campaign on student knowledge among two undergraduate nursing cohorts. Methods: A quasi-experimental research (pre/post-test design) is selected to achieve the aim of this study. The study is conducted at King Saud bin Abdel-Aziz University Health Science College. A sample of 82 undergraduate student nurses is allocated from third and fourth years. A structured interview questionnaire is designed to assess the undergraduate student nurses’ cohorts’ level of knowledge regarding first aid. Results: The study reveals a statistically significant improvement of the two undergraduate nursing cohorts’ level of knowledge in post-test compared to their pre-test scores. A non-statistically significant difference is revealed between two undergraduate nursing student cohorts (3rd and 4th year) level of knowledge after exposure to awareness session. Conclusion: The study provides evidences of the efficacy of awareness campaigns to raise awareness of such a critical issue as first aid among nursing college students, recommending a separate first aid course for undergraduate nursing students once they start their major nursing courses. The study also recommends further studies for evaluating the effect of awareness campaigns as an active student learning method.

Conceptual Change Model

This study contributes to a growing literature that investigates vocational students’ conceptual understanding of electricity by proposing a multidimensional and pragmatic approach to conceptual change. Conceptual change model-based activities were designed in a six-stage conceptual change model and were incorporated into a four-week course. The effectiveness of these activities was measured in terms of changing these students’ misconceptions about simple electric circuits towards scientifically accepted ideas in terms of their revolutionary versus evolutionary nature and the extent of transfer of learning. Transformative mixed methods research design was used consisting mainly of a one-group pre-test post-test design with DIRECT Test 1.2 as a research instrument. Paired samples t-test analysis for 15 students’ test scores indicated that there was a statistically significant difference between students’ pre- and post-test scores. The results of the frequency analysis in both pre- and post-tests show a significant percentage drop in the number of students having the identified misconceptions. The majority of students during post pre-test interviews justified their answers incorrectly, but more than 80% answered correctly in the post post-test interview. Key words: conceptual change, conceptual change model, electric circuits, misconceptions, vocational education.

Hipertensi (silent killer) merupakan suatu keadaan dimana adanya peningkatan tekanan darah baik systole maupun diastole yang abnormal. Kondisi ini yang menimbulkan kecemasan pada pasien hipertensi. Kecemasan yang dialami pasien hipertensi justru akan memperburuk kondisi hipertensinya. Penatalaksanaan kecemasan pada pasien hipertensi terdiri dari terapi farmakologi dan non farmakologi. Salah satu terapi non farmakologi yang bisa digunakan adalah wet cupping (bekam). Bekam akan menstimulus sekresi hormon ?-endorphin yang akan memberikan efek anti nyeri dan juga efek anxiolityc (anti cemas). Dengan demikian, peneliti melakukan penelitian lebih lanjut, terkait wet cupping (bekam) dalam penurunan kecemasan pada pasien hipertensi. Penelitian ini menggunakan desain penelitian pre-experiment dengan model rancangan pre-post test, dengan jumlah responden 25 orang. Instrumen dalam penelitian ini dengan menggunakan kuesioner Zung-Self Anxiety Rating Scale (ZSAS) dengan 20 pertanyaan. Analisis penelitian menggunakan uji normalitas dengan menggunakan Shapiro-Wilk dan analisis uji Paired T-test. Hasil analisis menunjukan bahwa terdapat perbedaan yang signifikan dengan nilai p-value 0.000. Sehingga dapat disimpulkan bahwa wet cupping (bekam) efektif untuk menurunkan kecemasan pada pasien hipertensi di Posbindu PTM Wijaya Kusuma Taskombang Palbapang Kecamatan Bantul Kabupaten Bantul Daerah Istimewa Yogyakarta. Diharapkan peneliti selanjutnya dapat melakukan penelitian dengan menambah variabel atau pada penyakit yang berbeda.   Hypertension (silent killer) is a condition where there is an increase in blood pressure both systole and diastole which is abnormal. This condition causes problems in hypertensive patients. Hypertension will worsen the condition of hypertension. Management is completed in hypertensive patients consisting of pharmacological and non-pharmacological therapies. One non-pharmacological therapy that can be used is wet cupping. Wet Cupping will stimulate the secretion of the hormone ?-endorphin which will provide an anti-pain effect and also anxiolityc (anti-anxiety) effect. Thus, researchers conducted further research, related to wet cupping. This study used a pre-experimental research design with a pre-post test design model, with 25 respondents. The instrument in this study used the Zung-Self Anxiety Rating Scale (ZSAS) questionnaire with 20 questions. Analysis of the study used a normality test using Shapiro-Wilk and paired T-test analysis. The analysis showed a significant difference with a p-value of 0,000. Wet cupping (cupping) is effective for reducing risk in hypertensive patients in Posbindu PTM Wijaya Kusuma Taskombang Palbapang, Bantul, Special Region of Yogyakarta. It is hoped that further researchers can conduct research by adding variables or in different diseases.
