식품첨가물의 올바른 이해를 위한 초등학생용 스마트 교육 매체 개발
황보미,검선아,김정원 한국실과교육연구학회 2014 實科敎育硏究 Vol.20 No.3
이 연구는 초등학생들의 식품첨가물에 대한 인식을 조사하여 그 실태를 분석하고, 이를 기반으로 식품첨가물에 대한 올바른 이해를 돕는 스마트 교육 매체인 앱(App)을 개발하는 데 목적을 두고 수행되었다. 이를 위해 2013년 3~4월에 걸쳐 서울 및 경기도의 4~6학년 초등학생 총 370명을 대상으로 식품첨가물에 대한 인식과 정보요구도 설문조사를 실시하였다. 설문에서 는 식품첨가물에 대한 인식과 정보요구도, 앱 선호도에 맞춰 내용을 구성하였으며, 362부(유효 표본 수거율 97.8%)를 대상으 로 통계 분석을 실시하였다. 연구 결과를 바탕으로 연구진의 브레인스토밍과 전문가 자문을 거쳐 ‘푸드애디와 놀자’라는 앱 을 개발하였다. 이후 서울지역 초등학교 5, 6학년 학생 4개 학급, 총 105명을 대상으로 개발된 앱을 활용한 수업을 실시하였 다. 일주일간의 시범적용 기간을 거친 후 사후설문지를 활용하여 개발된 앱의 효과성을 평가하였다. 이 연구를 통하여 얻은 결론은 다음과 같다. 첫째, 초등학생들의 식품첨가물에 대한 인식을 조사한 결과, 식품첨가물의 안전성에 대해 비교적 높은 불안감을 갖고 있는 것으로 나타났으며, 이에 반해 식품첨가물에 대한 전반적인 인지 정도는 낮은 것으로 나타났다. 둘째, 개발된 앱 ‘푸드애디와 놀자’에서는 식품첨가물의 역할, 필요성, 종류 등 전반적인 정보에 대하여 만화, 조작활동, 게임 활동 등 다양한 정보전달 방식을 활용하여 내용을 구성하였으며, 적용 결과 앱을 사용하여 교육을 한 후에는 식품첨가물의 안전성에 대한 인식이 긍정적으로 바뀌어 효과적인 위해정보전달(risk communication)이 일어났음을 확인할 수 있었다. 식생활교육을 위해 개발된 다양한 매체가 홍보 미비로 인하여 널리 활용되고 있지 못한 점을 감안할 때, 향후 교사 대상으로 본 연구에서 개발된 앱을 포함하여 다양한 식생활교육용 스마트 매체의 활용에 대한 홍보가 필요하다. This study was carried out to develop a smart application (App) to provide sound information on food additives and food safety to elementary school students as a risk communication tool. A survey was conducted from 370 elementary school students in Seoul and Gyeonggi Province to find out the perception, information demand on food additives and preference tendency about smart application. Based on the survey results and consulting from food science experts, an App called 'Let's Play with Food Addy' was developed. Then it was applied to 105 students to evaluate the effectiveness as an educational tool. The conclusions of the study were as follows. First, the elementary school students appeared to have ambiguous fears on the safety of food additives, and were curious about the function, necessity, and the types of food with food additives. Second, an App consisting of 6 menus of Food Addy’ story, webtoon of food time machine, cooking activity, OX quiz, animation, and Addy's library, were developed to suit the needs of elementary school students by implementing various activities and animation. A change in the perception of children on food additives was observed after intervention, suggesting the effectiveness of the App as a risk communication tool. Third, even though there are lots of educational material on food education, they have not been widely shared among elementary teachers. Therefore, the efforts to share these educational tools are necessary through teacher's workshops, training programs and so on.
Emergence of Norovirus GII.17-associated Outbreak and Sporadic Cases in Korea from 2014 to 2015

Human norovirus are major causative agent of nonbacterial acute gastroenteritis. In general, genogroup (G) II.4 is the most prominent major genotype that circulate in human population and the environment. However, a shift in genotypic trends was observed in Korea in December 2014. In this study, we investigated the trend of norovirus genotype in detail using the database of Acute Diarrhea Laboratory Surveillance (K-EnterNet) in Korea. GII.17 has since become a major contributor to outbreaks of norovirus-related infections and sporadic cases in Korea, although the reason for this shift remain unknown.
Occurrence of Norovirus GII.4 Sydney Variant-related Outbreaks in Korea

Human noroviruses are major causative agents of food and waterborne outbreaks of nonbacterial acute gastroenteritis. In this study, we report the epidemiological features of three outbreak cases of norovirus in Korea, and we describe the clinical symptoms and distribution of the causative genotypes. The incidence rates of the three outbreaks were 16.24% (326/2,007), 4.1% (27/656), and 16.8% (36/214), respectively. The patients in these three outbreaks were affected by acute gastroenteritis. These schools were provided unheated food from the same manufacturing company. Two genotypes (GII.3 and GII.4) of the norovirus were detected in these cases. Among them, major causative strains of GII.4 (Hu-jeju- 47-2007KR-like) were identified in patients, food handlers, and groundwater from the manufacturing company of the unheated food. In the GII.4 (Hu-jeju-47- 2007KR-like) strain of the norovirus, the nucleotide sequences were identical and identified as the GII.4 Sydney variant. Our data suggests that the combined epidemiological and laboratory results were closely related, and the causative pathogen was the GII.4 Sydney variant strain from contaminated groundwater.
Epidemics of Norovirus GII.4 Variant in Outbreak Cases in Korea, 2004-2012

Norovirus GII.4 is recognized as a worldwide cause of nonbacterial outbreaks. In particular, the GII.4 variant occurs every 2-3 years according to antigenic variation. The aim of our study was to identify GII.4 variants in outbreaks in Korea during 2004-2012. Partial VP1 sequence of norovirus GII.4-related outbreaks during 2004-2012 was analyzed. The partial VP1 sequence was detected with reverse transcription-polymerase chain reaction, seminested polymerase chain reaction, and nucleotide sequence of 312-314 base pairs for phylogenetic comparison. Nine variants emerged in outbreaks, with the Sydney variant showing predominance recently. This predominance may persist for at least 3 years, although new variants may appear in Korea.
