No full text目前全世界已有200萬人接受過永久性心律調節器治療，且每年仍在不斷增加中。心 律調節器為一人工能量輸出系統，包括激搏、電極及連接二者間的導線三部份。本文 主在介紹心律調節器各個組成在現今科技的發展情形，護理及居家照護教導上的改變 及運用。期使護理人員對心律調節器有更完整的認識，並能對病患及家屬做正確的教 導及護理，減輕病患的焦慮及縮短適應期
高血壓病患進行中度運動之短期與長期效應
No full text本研究評估高血壓病患運動之安全性與有效性。運動組10位高血壓病患依規劃進行運 動，對照組10位則否。運動以50%~85%最大心跳儲備值（HRmaxRev）為強度，每週2次 ，每次60分鐘，為期三個月。兩組於三個月前後均測量其最大攝氧量（VO2max），休 息時心跳、血壓、與血脂濃度；運動時測量其運動當時的心跳血壓反應與熱量消耗。 數據顯示個案達到50%~85% HRmaxRev之運動量為其最大攝氧量之55%±13%，約是5.5 ±1.1MET，屬中度運動；此運動使個案血壓升高，尤以前一個月及前10分鐘的熱身期 為甚，但心跳不會超過120次/分、收縮壓不會超過220mmHg，舒張壓不會超過110mmHg ，一旦熱身足、身體逐漸適應運動，血壓有下降的趨勢。50%~85%最大心跳儲備值的 運動強度使個案每次有300Kcal以上的熱量消耗。如此運動三個月體重與血脂均無明 顯變化；運動組平均心跳減少3.7次/分，平均收縮壓下降17 .5mmHg，平均舒張壓下 降8.8mmHg，達統計上意義，心肺適能尚無明顯變化；對照組休息時心跳血壓無明顯 變化，最大攝氧量則下降10%，達統計上意義。本研究顯示中度運動對高血壓病人是 安全的，且能有效降低血壓與維持心肺適能；指導高血壓病患保健運動時，須強調熱 身運動之重要性，在運動初期1個月及前10分鐘需加強血壓過度升高之監測，以維護 運動之安全。 The purpose of this study is to investigate the safety and effectiveness of moderate intensity exercise training on hypertensive patients. Subjects were recruited from hypertensive clinic, 10 in exercise group and 10 in comparison group. The exercise group conducted 50%~85% HRmaxRev exercise for 60 minutes twice a week for three months. Before and after the 3-month interval, each subject received treadmill test and serum lipids evaluation. During exercise, the blood pressures of the subjects were taken every 5~10 minutes. The results were as following. The intensity of exercise at level of 50%~85% HRmaxRev is about 55+13% of VO2 max and is about 5.5+1.1 MET . Blood pressure increased during exercise, especially in the first 10-minutes of warm-up period. The highest blood pressure developed in the first month and then lowered down in the following months. The total calories consumed were above 300Kcal at 50%~85 % HRmaxRev exercise for 60 minutes. Before and after the 3-month interval, subjects in both groups had no significant change in body weight and serum lipids levels. Subjects in exercise group had significant reduction of resting heart rate (3.7 bpm), SBP (17.5 mmHg) and DBP (8.8 mmHg), with insignificant increase in VO2max . Subjects in the comparison group did not have any significant change in body weight, serum lipids levels, resting heart rate, and blood pressure. The VO2max decreased 10% significantly (p<0.05). This study demonstrated that moderate intensity exercise was effective for reducing blood pressure and preserving cardiopulmonary fitness for hypertensive patients. For safety, patients need to be supervised for blood pressure change in the beginning stage, especially during their warming-up process
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
