본 연구의 목적은 수업 시 스마트기기에 적용할 수 있는 나무 이미지를 인식하고 분류하여 정확도를 측정할 수 있는 효율적인 모델을 제안하는 것이다. 2015개정 교육과정으로 개정되면서 초등학교 4학년 과학교과서의 학습 목표에서 스마트 기기 사용한 식물 인식이 새롭게 추가 되었다. 특히 나무 인식의 경우 다른 사물 인식과 달리 수형, 수피, 잎, 꽃, 열매의 부위별 특징이 있으며, 계절에 따라 모양 및 색깔의 변화를 거치므로 인식률에 차이가 존재한다. 그러므로 본 연구를 통해 컨볼루션 신경망 기반의 사전 학습된 인셉션V3모델을 이용하여 재학습 전 후의 나무 부위별 인식률을 비교한다. 또한 각 나무의 유형별 이미지 정확도를 결합시키는 방식을 통해 효율적인 나무 분류 방안을 제시하며 교육현장에서 사용하는 스마트기기에 적용 할 수 있을 것이라 기대한다.

The purpose of this study is to analyze elementary school students' pre-concept of electromagnet and to investigate effects of instruction through social interactions on conceptual changes of the electromagnet. For the purpose, 108 elementary school students of 3 classes were selected from the 6th grade. They were divided into the control group I, control group II and experimental group. The control group I was treated through traditional instruction on the basis of text book. The control group II was instructed with a modified version of the textbook to help them better understand the concept of electromagnet. The experimental group was treated through instruction on the basis of the above modified version of the text book and social interactions. Conceptual changes on electromagnet before and after the treatment were quantitatively and qualitatively analyzed using the identical test. The students' styles of social interaction were qualitatively analyzed with tape records of their discussions and work sheets. Effects of instruction through social interactions based on radical constructivism on the 6th-grade elementary school students' concept of electromagnet were examined here. The results were described as follows. Firstly, after the treatment, the experimental group was statistically significantly higher in mean values of conceptual understanding and academic achievement than both the control group I and II. Secondly, styles of social interaction in the three sub-groups of the experimental group were qualitatively analyzed, among the threes, high- and medium-level sub-groups were higher in the frequency of linguistic social interaction than the low-level sub-group. Those students who were excellent in communication skills actively participated in linguistic social interactions. In discussions among the three sub-groups, students of the high- and medium-level sub-groups provided explanations or information while those of the other sub-group sometimes were passive by just listening, but in large actively participated in communication. In conclusion, instruction through social interactions was effectively changed in the 6th-grade elementary school students' concept of electromagnet.

This study investigated the food behavior and nutritional status of children using the Nutrition Quotient (NQ). The subjects for this study were 974 students and their parents who lived in Seocho-gu, Gwanak-gu, and Dongjak-gu, Seoul. The average NQ score of the subjects was 68.3, which was a medium grade. The mean scores for balance and moderation were above the thresholds, whereas the mean scores for diversity, regularity, and practice did not reach the thresholds. According to the results of evaluation by NQ, the subjects may have insufficient intake of calcium, iron, potassium, zinc, vitamin A, and vitamin C. NQ and NQ factors were different according to the general characteristics and home background characteristics of the subjects. The mean scores for the moderation factor was significantly lower as the eating out frequency increased (p<0.001). The mean scores for balance, moderation, and regularity factors were significantly higher, with higher parents educational level. It is necessary to choose diverse side dishes, vegetables and also foods with balanced nutrition when eating out.

The purpose of this study was to evaluate the current status of dietary habits and dietary life competency of elementary school parents, who are influential to the dietary life of their children and family. A survey was conducted with 362 elementary school parents living in Seoul and Gyeonggi province by using a self-administered questionnaire consisting of 53 questions on dietary habits, dietary life competency, home cooking frequency, and dietary education needs. The results were as follows: The scores of dietary habits and dietary life competency were 76.35 and 74.51 out of 100, respectively, suggesting a need for improvement. Parents with higher monthly income, demonstrated higher scores of both dietary habits and dietary life competency (p<0.001). As expected, female parents showed higher scores of dietary life competency than male parents (p<0.01). there was also a close relationship between the scores of dietary habits and dietary life competency (r=0.58). The parents with high scores for dietary habits and dietary life competency showed a significantly higher frequency of home cooking (p<0.001) compared to medium- or low-scored parents. Most parents answered that dietary education need to be started earlier, and that their main source of dietary life information was mass media. They also showed a preference for real experience and practice for dietary education. The above results showed that there is a close relationship between dietary habits and dietary life competency, and suggest that continuous education is necessary to improve the dietary habits and dietary life competency of elementary school parents. Because monthly income appeared to be the most influential socioeconomic factor for the parents' dietary habits and dietary life competency, continuous efforts on dietary education are necessary to reduce the score gaps in these categories.

The microbial contamination levels of school classrooms were assessed as foodservice environments for elementary students. Two elementary schools located in Kyunggi-do were selected, and the total plate counts (TPC) and coliforms were measured from the classroom facilities, including the tables, chairs, floors, shelves, doors, as well as the hands of students, and the air of classrooms. The TPC of the classroom facilities were relatively low ranging from 2.30 to 3.79 log CFU/100 cm$^2$. The TPC counts from the hands of serving students and served students, were 6.39 and 5.33 log CFU, respectively, and the TPC counts of the foodservice utensils were <3.00 log CFU/ea before use and 4.77 CFU/ea after use. The air samples of 'empty classrooms during physical education', 'after physical education class', and 'during lunch' showed the contamination levels of 26 CFU/m$^3$,392 CFU/m$^3$, 364 CFU/m$^3$, respectively, suggesting that the microbial levels in the air varies greatly depending on the class activity before foodservice. When the TPCs of the air during lunch were measured from 18 classrooms, the levels ranged from 76 to >2228 CFU/m$^3$. Coliforms were not detected in the classroom facilities; however, air samples of the classrooms showed 1${\sim}$2 CFU/m$^3$. The above results show that classroom air and the hands of students, can have high levels of microbial contamination, which must to be controlled for safer school foodservice.

The objectives of this study was to explore the knowledge, attitudes, and perceptions of elementary school students towards trans fatty acids. In addition, the students' preferences and consumption frequencies of processed food items containing trans fats, as well as their food behaviors relating to snack consumption, were investigated. The study population consisted of students from seven provinces, including Seoul, Busan, Daegu, Kwangju, Gyungnam, Chungnam, and Kangwon. Two schools were selected in each province and one class was randomly chosen in each school. All students from the selected classes were surveyed onsite (N=951). The data were analyzed with chi-square tests and t-tests using SPSS/Windows (ver.15.0) program. The results showed that the students' knowledge levels toward trans fatty acid were very low, particularly on the production process of trans fats. The students perceived that trans fatty acids can cause health problems and should be consumed in low amounts. They also felt there is a need for a good nutrition education on trans fats. Furthermore, the students responded that their most preferred foods were in the order of breads, biscuits, and snacks. The most frequently consumed snack item among 2nd graders was biscuits and among 5th graders it was breads. It was also found that 90% of the students had snacks once a day, and of them, 58% prepared their own snacks. Based on this, we propose that students who allowed to choose their own snacks should be carefully educated on trans fatty acids to prevent excessive consumption of high trans fat foods.
