This study was conducted to examine the effect of elementary science class using name card method on scientific learning motivation and academic achievement of elementary students. Two sixth grade classes were divided into experimental group and comparison group to treat the experimental group with elementary science class using name card method. General class according to teacher manual was implemented for the comparison group. Elementary science class applying name card method was conducted for 10 sessions throughout the experimental period of 8 weeks. The results of this study were as follows. First, elementary science class with name card method was effective in improving scientific learning motivation. Second, elementary science class with name card method had significant effect on improvement of scientific learning academic achievement. The study results showed that elementary science class with name card method was effective for scientific learning motivation and academic achievement of elementary students.

Background: About 40,000 to 60,000 images are analyzed for a complete interpretation of a single capsule endoscopy case. Diagnostic yield of capsule endoscopy for occult gastro-intestinal bleeding is between 60 and 70 percents. However overall abnormality detection rate is roughly 30 to 50 percents due to excessive workload which can result in examiners missing significant lesions during the review of capsule endoscopy images. Because of the poor detection rate, meticulous analysis ofimages has become critical for safe patient-care. Impact of re-review on the detection rate of abnormal lesions is not known. In this study, we compare the detection rates of abnormal findings in different re-review methods for capsule endoscopy. Methods: Capsule endoscopy for 20 patients were conducted. Indications include obscure gastro-intestinal bleeding, small bowel tumor and chronic abdominal pain. Four endoscopists interpreted capsule endoscopy images. Second reviews were performed by the same clinician (A-A) and other clinician (A-B). Three modes of interpretation of capsule endoscopy were compared; A vs. A-A vs. A-B. PillCami SB, GiveniImaging Ltd. was used for the evaluation. Collected images were reviewed with RAPID Readeri 5. Consensus standard of small bowel diagnosis had been established by joint review sessions with highly experienced endoscopists. Results: The mean age of subjects was 52.4±20.03 (12 Male, 8 Female). The detection rate of the re-reviewed group done by a single clinician (A-A) was higher than the single review group (A) (82.7% vs. 55.5%, p<0.05). The detection rate of re-analysis by different clinicians (A-B) was also higher than the single review group (A) (85.5% vs. 55.5%, p<0.05). Conclusions: Because re-reviewing capsule endoscopy added more information for patients, re-review may be effective enough to be considered as a routine interpretation protocol.
