Laser cutting error has large influence on the beam width of intravascular stents. Minor random variation in beam width of stents may significantly impact the expansion uniformity. In this paper, the relevant factors that may affect the beam width during the manufacture are investigated. Based on the randomization model, the pattern how the factors affect expansion uniformity is explored, and the method for calculating uniformity index is proposed. A detailed computation is made on the width randomization for the two expansion elements. The results show that with the increase of the value range of beam width, probability of uniformity index decreases gradually; the strengthening factor has large effect on the expansion uniformity. The method is meaningful for studying how the processing error affects expansion uniformity.

Abstract In most cases of shoulder injury at work, causation analysis is not clear-cut and requires detailed, thoughtful, and time-consuming causation analysis; traditionally, physicians have approached this in a cursory manner, often presenting their findings as an opinion. An established method of causation analysis using six steps is outlined in the American College of Occupational and Environmental Medicine Guidelines and in the AMA Guides to the Evaluation of Disease and Injury Causation, Second Edition, as follows: 1) collect evidence of disease; 2) collect epidemiological data; 3) collect evidence of exposure; 4) collect other relevant factors; 5) evaluate the validity of the evidence; and 6) write a report with evaluation and conclusions. Evaluators also should recognize that thresholds for causation vary by state and are based on specific statutes or case law. Three cases illustrate evidence-based causation analysis using the six steps and illustrate how examiners can form well-founded opinions about whether a given condition is work related, nonoccupational, or some combination of these. An evaluator's causal conclusions should be rational, should be consistent with the facts of the individual case and medical literature, and should cite pertinent references. The opinion should be stated “to a reasonable degree of medical probability,” on a “more-probable-than-not” basis, or using a suitable phrase that meets the legal threshold in the applicable jurisdiction.

After pointing out the drawbacks of the approach commonly used to analyze the data collected in controlled clinical trials carried out to evaluate the analgesic effect of potential agents, the authors suggest a procedure suitable for analyzing data coded according to an ordinal scale. In the first stage a multivariate analysis is carried out on the codec! data and the projection of each result in the space of the most relevant factors is obtained. In the second stage the whole set of these values is processed by distribution-free tests. The procedure has been applied to data previously published by VENTAITBIDDA et al. [18].

Reading Comprehension Skills

Reading comprehension is a reading activity that aims to obtain adequate understanding and interpretation of the meanings contained in written symbols. the reading process is divided into three stages, such as pre-reading, reading, and post-reading. But the reality is that many of the students still experience difficulties in reading comprehension learning. Therefore, researchers applied an Accelerated Learning approach to improve students' reading comprehension skills. The results showed, the assessment of the process of reading students' skills for each assessment indicator was in the value range of 78.35% to 87.35% which was included in the good and very good category. While the results of the assessment of the overall reading skills process were 82.32% with a very good category. Based on the results of the study it can be concluded that learning based on the accelerated learning approach can enhance reading comprehension skills of students in class V of the Primary school of 011 Air Emas, Singingi District.

Group Guidance

Assertive behavior holds important guidelines for the formation of a person's personality can be improved in group guidance, because in group guidance can be utilized the influence of a person or some individual against other members. This study aims to determine (1) the large influence of group guidance on assertive behavior in the expression of the mind, (2) large influence group guidance on assertive behavior in the expression of feeling, and (3) large influence group guidance on assertive behavior in the expression of mind to students. The research method used in this research is a simple correlation research method. The result of calculation obtained by value of porsentase influence group guidance to assertive behavior in expression of mind equal to 2,5%, in expression of feeling of porsentasenya equal to 4,4%, whereas in expression action only equal to 0,1%. So it can be concluded that group guidance has little effect on assertive behavior in the expression of thoughts, feelings, and actions. The overall influence of group guidance on assertive behavior is only 2.5%.   Perilaku asertif memegang pedoman penting bagi pembentukan kepribadian seseorang dapat ditingkatkan dalam bimbingan kelompok, karena dalam bimbingan kelompok dapat dimanfaatkan pengaruh-pengaruh seseorang atau beberapa individu terhadap anggota lainnya. Penelitian ini bertujuan untuk mengetahui (1) besar pengaruh bimbingan kelompok terhadap perilaku asertif dalam ekspresi pikiran, (2) besar pengaruh bimbingan kelompok terhadap perilaku asertif dalam ekspresi perasaan, dan (3) besar pengaruh bimbingan kelompok terhadap perilaku asertif dalam ekspresi pikiran pada siswa. Metode penelitian yang digunakan dalam penelitian ini yaitu metode penelitian korelasi sederhana. Hasil perhitungan diperoleh nilai porsentase pengaruh bimbingan kelompok terhadap perilaku asertif dalam ekspresi pikiran sebesar 2,5%, dalam ekspresi perasaan porsentasenya sebesar 4,4%, sedangkan dalam ekspresi tindakan hanya sebesar 0,1%. Sehingga dapat disimpulkan bahwa bimbingan kelompok berpengaruh kecil sekali terhadap perilaku asertif dalam ekspresi pikiran, perasaan, dan tindakan. Yang secara keseluruhannya pengaruh bimbingan kelompok terhadap perilaku asertif hanya sebesar 2,5%.
