Note-Taking as a Self-Regulated Learning Strategy and Cognitive Style : Impact on Immediate and Delayed Learner's Academic Performance

Chung, Jae-Sam,Ki, Hye-Hee 이화여자대학교 사범대학 교과교육연구소 2004 East west education Vol.21 No.-

This research was to investigate the impact of cognitive style and self- regulated learning strategy such as note-taking methods on learners' students' academicper formance. Statistical analysis result showed that both cognitive style and note-taking methods did not have a significant effect on an immediate test.However, there is a significant main effect of cognitive style on a delayed test. Field-dependent students significantly outperformed field-independent students on the delayed test. Also, the main effect of note-taking methods on the delayed test was significant. Students who took notes in a matrix scored higher on the delayed test than did students who took notes in a free format.

Chung, Jae-Sam 이화여자대학교 교과교육연구소 2001 East west education Vol.18 No.-

The purpose of this study was to review literature, theories, and models on interaction, online discussion, and e-learning in the web-based learning environment. Literature reviews suggested ten factors: the attitude toward computer-mediated communication, the attitude toward writing, intrinsic/extrinsic motivation, previous knowledge on the subject, the relevance of the discussion topic, the interaction with instructors, physical environment, psychological environment, support. These factors can be categorized into 3 groups such as learner-related factors, design-related factors, and environment-related factors. Based on this study, the following recommendations were offered: alleviate anxieties on writing, assign students to the discussion group according to the previous knowledge on the topic, implement motivational strategies, assign grades for adequate portion, offer discussion topic which learners consider relevant to them, interact with learners actively, facilitate learners to interact with peer learners. Implications this inquiry into interaction and online discussion for online learning and instruction were also discussed.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

In this paper, presented are experimental results of sensorless driving of a brushless dc motor with a double axial type rotor. The rotor position is estimated using back EMF on the driving terminals. For the estimation of the position of the rotor, a bandpass filter with 90 degrees phase shift is used. A new starting algorithm is proposed for the driving of the motor at standstill. The proposed algorithm demonstrated better performance in that speed of the motor increases more smoothly from standstill to a normal operating point. The sensorless driving system result showed that it works well in the range from 300 rpm to 5000 rpm.

This experiment was carried out to obtain indispensable information to establish comprehensive cultural method of rice in direct seeding on dry paddy at Chungbuk Agricultural Research and Extension Services. Effect of seeding date on dry matter production, yield components and yield were studied. Seeding on May 5 ensured the highest maximum number of tillers, while transplanting on May 20 gave the highest rate of effective tillers. Number of effective tillers was greater in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. Lengths of upper three leaves were increased at later seeding, but leaf width was not affected by seeding date. Ratio of leaf blade weight was higher in earlier seeding during 30 days before heading but was higher in later seeding during 30 days after seeding, and was higher in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. CGR, RGR and NAR were not significantly different among seeding dates during 30 days before heading, but were lower in later seeding during 30 days after seeding. LAR was not affected by seeding date during 30 days before heading, but was higher at seeding on May 5 in heading date and during 30 days after heading. Dry weight of leaf blade, leaf sheath and culm, ear and total biomass during 30 days before heading and heading were highest in May 5 seeding. Daekwanbyeo and Hwaseongbyeo in May 5 seeding and Hwajinbyeo in April 20 seeding brought the highest yield with greater number of spikelets, higher ripening ratio and greater 1,000 grain weight, and harvest index and grain/straw ratio were Increased at earlier seeding. There were significantly positive correlations between number of panicles per m2 and LAI at 30 days before heading and heading, dry matter weight of leaf blade and total mass at heading. On the other hand, there were significantly negative correlations between seeding date and ripened grain ratio. 1,000 grain weight and yield, and between 1,000 grain weight and leaf length of 2nd, respectively.

물체의 Free Body Diagram(FBD) 에 대한 정량적인 고찰

권재술,김영삼 한국교원대학교 과학교육연구소 1995 청람과학교육연구논총 Vol.5 No.1

현행 국내와 국외의 물리 교재들은 대부분 물체의 FBD에 대하여 일치된 표시 방법을 갖고 있지 않다. 그것은 물체의 평형을 생각할 때, 평형에 관한 제1조건만 적용하거나 제2조건을 고려할지라고 정성적으로만 다루었기 때문이라고 생각한다. 현행 물리 교재들이 채택하고 있는 표시방법들은 물체의 크기를 무시할 수 있거나, 회전을 고려하지 않을 경우는 문제가 없으나 회전을 고려해야 하는 경우는 설명에 어려움이 있다. 무엇보다 교과서에서 FBD를 정확히 표시하는 것은 매우 중요한 일이라고 생각하며, 본 연구에서는 대부분의 물리 교재들이 현재 사용하고 있는 FBD와 관련된 문제점들을 찾아보고, 물체의 평형에 관한 제1, 2조건을 적용한 정량적인 분석을 통하여 올바른 FBD 표현 방안을 제안하고자 한다. The Free-Body Diagram (FBD) is widely used in introductory physics textbooks. It plays a key role in finding the net force and the net torque acting on a body. However, the representantions of the FBD vary from textbook to textbook in Korea, as well as in foreign countries. In the case of translational motion only, the methods of presenting FBD were not significantly different. However, in the case of rotational motion due to the torque produced by the external forces, the methods of drawing the FBD were significantly differenct. In this study, the researchers examined the FBDs presented in the textbooks in Korea and in foreign countries and extracted problems appearing in the textbooks. Finally, the researchers tried to suggest a correct method for drawing FBD, which would be applicable to the translational motion, as well as the rotational motion, of a body.
