The effects of a nutritional education program featuring cooking activities on 20 preschool children 6 years of age at a kindergarten in the Daegu suburb area. After applying the nutritional education program for 6 weeks, scores of dietary habits, dietary attitude and problematic dietary behaviors increased significantly from 3.68 to 3.83, 3.52 to 3.9 and 3.59 to 3.89, respectively (p<0.001). Problematic dietary habits, such as not eating a variety of foods, overeating, and having an unbalanced diet, were positively affected while problematic dietary behaviors, such as eating too much sweet food and liking instant foods, also underwent favorable changes. Among dietary attitudes, washing bands and brushing teeth before and after meals were the least changed items (0.15 out of 1). To improve dietary habits and behavior of preschool children, nutrition education programs cooking activities must be applied systematically.

The purpose of this study is to provide some suggestions for future improvement of scientific inquiry activities in Korean elementary science textbook. The modified framework of Lee(2005) and Millar et al.(1998) was used to compare inquiry activities in the Korean and Singaporean science textbooks. The results of this study are as follows: Korean text books have more activities than Singapore's, but both countries have similar time allotment for science classes. In the area of 'inquiry process skill', Singapore is more balanced in 'Basic inquiry process skills' and 'Integrated inquiry process skills' than Korea. Singapore's integrated inquiry rate is also higher than Korea's. Next the results of comparing leaning objectives to scientific inquiry activities shows that Korean text books tend to focus on 'contents objectives', while Singapore's text books focus on balancing 'contents objectives' and 'process objectives'. Korean science textbooks encourage students to communicate the results of experiments but in most case these communication activities are actually not performed. Lastly Korea and Singapore have low degree of openness in inquiry activities. Remarkably 'Suggest questions' are totally conducted by teachers. This study implies that Korean science textbooks should have lower amounts of inquiry activities to accomodate enough time for communication about results. Next we need to make balance not only 'Basic inquiry process skills' and 'Integrated inquiry process skills' but also 'Content objectives' and 'Process objectives'. Lastly we need to make student to be the leader in science classes through encouraging them to plan procedures for experiments and to discover results by themselves.

Purpose: A systematic review and meta-analysis of nutrition educational intervention studies was performed to assess the association between nutrition education intervention and fruit & vegetable (F&V) preferences and nutrition knowledge in preschool children. Methods: The relevant studies of nutrition education intervention and F&V preferences and nutrition knowledge published from January 2000 to June 2020 were located using PubMed, Web of Science, Cochrane Library, Research Information Sharing Service, Korean Studies Information Service System databases, and lists of references. A random-effects meta-analysis was conducted to estimate the standardized mean difference with a 95% confidence interval (CI). Subgroup analyses were performed to identify the association between nutrition education and F&V preferences and nutrition knowledge. Results: The results show that the effect sizes (ES) of F&V preferences and nutrition knowledge of preschool children were 0.31(95% CI, 0.23, 0.39), and 1.69(95% CI, 1.27, 2.12), respectively. The result of subgroup analysis, nutrition education focused on F&V (F&V preferences, ES: 0.32; nutrition knowledge, ES: 2.09) presented a slightly larger effect than general nutrition education (F&V preferences, ES: 0.26; nutrition knowledge, ES: 1.62). As for the type of exposure to F&V, direct exposure education (F&V preferences, ES: 0.40) had a greater effect than indirect exposure (F&V preferences, ES: 0.26). This meta-analysis showed that nutrition education intervention had positive effects on the F&V preferences and nutrition knowledge in preschool children. Conclusion: In conclusion, from the meta-analysis and subsequent subgroup analysis, we found that varied types of nutrition education intervention had varying effects on F&V preferences and nutrition knowledge in preschool children.

We measured PM2.5 and PM10 (particulate matter less than 2.5 ㎛ and 10 ㎛ in diameter, respectively) simultaneously at 16 locations around an elementary school and classrooms in Busan and Pyeongtaek, South Korea. In this study, we compared the results of this field intensive with those in the literature (144 cases of 30 studies), focusing on I/O (Indoor/Outdoor) ratios. We also reviewed the results of previous studies, categorizing them into related sub-categories for indoor-activities, seasons, building-uses, and the surrounding environment. We conclude that indoor PM10 is affected more by indoor-sources (e.g., physical activities) than PM2.5 in the absence of combustion sources like smoking and cooking. Additionally, PM10 and PM2.5 likely have different indoor-outdoor infiltration efficiencies. Conclusively, PM10 in classrooms can be more sensitively affected by both indoor activities and ambient concentrations, and mechanical ventilation can be more efficient in reducing PM concentrations than natural ventilation.

This study was conducted to investigate the state of cooking activities at home and at school among the elementary school 6th graders in Gyeongbuk province. For 'interest in cooking', 86.9% of the subjects answered 'very interested,' and the answers were significantly different according to sex(male 45.6%, female 77.8%, p<0.01). Above 70.0% of the subjects answered that they could cook by themselves and the responses were significantly different according to sex(male 35.3%, female 66.7%, p<0.01). The children had experiences of chopping(64.8%), slicing round(62.3%), cutting dice(62.3%), cutting julienne(53.3%), cutting diagonally(45.1%), slicing semicircle(34.4%), and cutting paysanne(22.1%). 93.4% of the subjects had cooking experience at home and most parents(95.1%) were positive to children's cooking at home. The reasons for cooking at home were 'like to cook'(55.3%), 'to satisfy hunger'(17.5%), 'to eat foods that I want'(14.0%), etc. The only 10.7% of the subjects answered 'difficult' or 'very difficult' for the cooking classes at school. The 62.3% of the subjects have cooked the foods again at home that they learned at school, and the responses were significantly different according to sex(p<0.05). The foods that the children wanted to cook at school were pizza, spaghetti, Tteokbokki, hamburgers, etc. The children answered that they had difficulties in 'seasoning'(34.4%) and 'cleaning up after cooking'(21.5%). What the children wished about the cooking class of their schools included 'to cook more often'(35.8%), 'to cook more diverse foods'(29.7%), 'to have the school equipped with cooking tools and facilities'(14.8%), etc. Therefore, the cooking classes for the elementary school students need to be planned considering these results about children's cooking abilities, skills and demands.

전국에 1,000여개의 다문화 기관들이 활동 중이다. 그중 정부주도형인 여성가족부 지정 다문화가족지원센터 210여 곳을 제외한 나머지 기관들은 대부분 정부 민간 혼합형이거나 민간주도형 기관들이다. 정부주도형 기관들은 중앙정부와 지방자치단체로부터 운영비가 지원되지만 정부 민간 혼합형이나 민간주도형 기관들은 운영비를 기부금 또는 후원금에 의존한다. 그러나 경제위기의 도래로 기부금이나 후원금이 급감하는 상황에서 정부 민간 혼합형이나 민간주도형 기관들의 자립은 더욱더 어려워질 전망이다. 이러한 전망과는 달리, 지원 대상들과 다문화이슈는 지금보다 훨씬 더 늘어날 전망이다. 국내 이주민의 수는 매년 증가추세이다. 향후 2050년이 되면 전체인구의 10%가 외국인이라는 전망도 나온다. 외국인의 정주화 그리고 가족이민 증가에 따른 상이한 종교와 문화에 대한 편견 없는 이해와 대화가 강조될 것이며, 학교교육정책, 직업양성, 노동시장정책, 동등한 노동조건과 사회보장 요구, 사회적 차별에 대한 계몽정책 등 다양한 다문화 이슈도 부각될 것이다. 이처럼 다양한 분야에서 다문화 이슈를 가장 잘 다룰 수 있는 민간주도형 다문화기관의 자립 여부는 다문화 지원정책의 성패와도 연결된다고 볼 수 있다. 결국 민간주도형 다문화기관이 지금의 운영구조를 개선하고 재정적 자립을 확보하기 위해서는 다문화 관련 비즈니스모델 개발을 통해 다문화 기관들이 스스로 자립할 수 있는 사회적기업에 관심을 가질 수밖에 없다. 사천다문화통합지원센터는 비영리민간단체로 지난 13년 동안 창조적인 다문화 사업들을 추진하여 괄목할만한 성과를 거두었다. 그러나 일반 기부금이나 후원금으로 운영비를 충당하고 있는 상황에서 자립 기반 구축을 위한 비즈니스 모델 개발은 필수적이었다. 마침내 요리조리아시아 협동조합을 만들어 청소년 공정여행 프로그램인 세계로여행학교와 아열대채소 농장을 운영중에 있다. 뿐만 아니라 기업의 CSR(Corporate Social Responsibility) 해외공헌사업도 위탁받아 운영하고 있다. 본 연구에서는 사천다문화통합지원센터가 그동안 진행해 온 청소년 공정여행과 아열대채소 농장을 다문화기관의 비즈니스 모델적 측면에서 사례 분석한 후, 벤치마킹을 통해 민간주도형 다문화기관들로 확대시킴으로써 사회혁신의 기회를 증대시킬 방안을 제시하였다.

Objectives: The purpose of this study was to examine the effect of cooking and art activities on cognitive function and depression of dementia patients. Methods: The study was carried out on 34 dementia patients (experimental group: 17 persons, control group: 17 persons) at 65 years old or more who correspond to a total MMSE-M, MMSE-K point between 15 and 23 points instituted in a specialized nursing facility in Busan from November 30, 2007 to February 20, 2008. The study used a nonequivalent pretest-posttest design. In previous survey, the study measured points of general characteristics, cognitive function and melancholy. To the experimental group, cooking art activities were carried out for 90 minutes every time and once every week for 12 weeks. Results: Analysis on data was performed using SPSS/WIN 14.0. In addition $x^2$-test, Fisher's exact test and t-test were used for testing of homogeneity and ANOVA was performed for testing of hypothesis. The results of this study are as follows. 1. Hypothesis 1 that 'The experimental group with cooking art activities will show a higher point of cognitive function than the control group without cooking art activities' was supported (F=65.497, p<0.001). 2. Hypothesis 2 that 'The experimental group with cooking art activities will show a lower point of melancholy than the control group without cooking art activities' was supported. (F=27.463, p<0.001) Conclusions: From the above results, cooking art activities showed a significant difference in the increase in cognitive function and reduction in melancholy of dementia patients.

The purpose of this study was to develop a fusion-food cooking program and apply that to sixth grade elementary school students, and to investigate its' effects on their knowledge, preferences, and perceptions of Korean traditional foods. The program focused on ten components. Students learned the general features of Korean traditional foods and Western foods in the 1st lesson. They learnt about kinds, nutrition value, and histories of kimchi, Tteok (rice cake), and Jeon (pan fried food), and cooked two fusion-foods of kimchi, Tteok, and Jeon each. As a result of learning about those food items, the students advanced their knowledge (p < 0.001) of kimchi, Tteok, and Jeon. Their preferences for Tteok (p < 0.05) and Jeon (p < 0.01) were increased, but those for kimchi remained unchanged. The interest (p < 0.05) and preferences (p < 0.01) for the general Korean traditional foods were increased. In conclusion, our results suggested that the fusion-food cooking program had the ability to improve elementary school students' perceptions of Korean traditional foods by increasing their knowledge, preferences, and interest in them. Furthermore it was considered that the program could help students understand the value of Korean traditional foods and in turn may encourage them to consume such food items more frequently. Since the fusion-food cooking activity program can be a good learning program as shown by the results of this study, more fusion-foods cooking activity programs, which are not discussed in this study, should be evaluated and developed in the future.
