웹 환경에서 그래픽 자료유형과 아동의 인지양식이 수학과 공간지각력 형성에 미치는 효과
왕선희,김보경,백영균 한국교육학회 2003 敎育學硏究 Vol.41 No.2
본 연구의 목적은 웹 환경에서 아동의 인지양식에 따라 정적인 3차원 그래픽 학습자료 유형과 동적 인 3차원 그래픽 학습자료 유형이 아동의 공간지각능력 형성에 미치는 영향을 규명하여 아동의 특성에 맞는 효과적인 학습자료 유형을 모색하는데 그 목적이 있다. 본 연구의 실험집단인 초등학교 5학년 113명을 인지양식 검사를 통해 장의존적 집단과 장독립적 집단으로 분류하고, 각 집단에게 웹을 이용하여 동일한 교과내용을 정적인 3차원 그래픽 학습 자료와 동적인 3차원 그래픽 학습자료로 각각 처치하였다. 연구 결과 웹 환경에서 동적인 3차원 그래픽 자료가 정적인 3차원 그래픽 자료보다 수학과 공간지각력 형성에 미치는 효과가 높게 나타났으며 장독립적인 인지양식을 가진 학습자가 장의존적인 인지양식을 가진 학습자보다 수학과 공간지각력 형성이 높게 나타났다. 또한 그래픽 자료 유형과 아동의 인지양식은 수학과 공간지각력 형성에 대하여 상호작용 효과를 나타내었다.

미숙아의 정맥영양제 투여에 의한 간기능 부작용 발생에 있어서 Fish Oil 함유 대 Soybean Oil 함유 지방유제의 영향비교

Objective : Parenteral nutrition (PN) is critical for growth and therapeutic effect in premature infants. However, long term PN is associated with development of PN associated liver disease (PNALD). Since the omega-6 fatty acid in soybean oil fat emulsion could be responsible for promoting PNALD, fish oil fat emulsion has been used to reduce this adverse effect. This study aimed to evaluate the efficacy of fish oil fat emulsion in reduction of PNALD. Methods : This study was designed for premature infants who were administered PN with fat emulsion for at least 4 weeks, at the Seoul St. Mary’s hospital neonatal intensive care unit. Between September 2013 and February 2014, preterm infants who received PN with soybean oil fat emulsion were classified as the SO group. From September 2014 to August 2015, preterm infants who received PN with fish oil fat emulsion were classified as the FO group. The change of aspartate transaminase (AST), alanine transaminase (ALT) and direct bilirubin (DB), weight, total protein, albumin and triglyceride (TG) were investigated on the first day and the last day of PN administration. Results : The level of AST decreased by 0.5 IU/L in the FO group, and increased 8.5 IU/L in the SO group (P=0.02). The ALT and DB increased to 13 IU/L and 0.18 mg/dL respectively, in the FO group, and 27.5 IU/L and 0.53 mg/dL respectively, in the SO group (P=0.051, 0.247). No significant difference was observed in weight and total protein. However, the change of albumin levels in the FO group was significantly greater than in the SO group (P=0.01). Also, TG levels decreased by/to 90 mg/dL in the FO group and increased by/to 4.5 mg/dL in the SO group (P=0.03). Conclusion : This study suggests that fish oil fat emulsion lowers the risk of PNALD. Subsequently, fish oil fat emulsion was effective in the improvement of nutritional status in preterm infants.

The purpose of this study was to develop a nutrition education website for children, especially those around the 4th-6th grade levels. Among the already existing websites providing nutritional information for children, 7 websites with comparable amounts of information were evaluated in terms of their topics, credibility, content, ease of use, and aesthetics. In addition, a survey was conducted to assess the need for nutrition information among 305 elementary students. The food pyramid was the topic offered most often on those websites. Information on nutrients, digestion, food safety, nutrition labeling, and healthy eating habits were available on the websites. Some of those websites also provided games or quizzes to attract the children's interest. However, some of the websites did not give any information on the person responsible for providing the information, which is most important in determining the credibility of the website. Other problems were that some information was too difficult for children, and some of the websites did not provide a way to search for information. According to the survey results, the topics that children wanted to know about were 'desirable weight', 'cooking', 'correct food choice', 'weight control method', 'calories consumed during exercise', but, they did not have a high interest in 'asking questions' 'books with nutrition messages', 'underweight', 'negative effect of weight control' and 'helping hungry children'. Based on these results, we developed a new nutrition education website, ifood' (http://ifood.or.kr). We focused on helping children develop healthy eating habits by providing information which is easy and practical for children. However, we neither included the program to assess their dietary intake, nor provided entertaining background sounds, which children like. Also, the game section is composed mainly of quizzes. Therefore, we need to further develop exciting games to teach nutrition to children. In the near future, the newly developed website should be evaluated by children regarding understandability and coverage of the contents as well as usability and design, and then revised to improve the educational effect.
