This study examined the relationship among supervision behaviors, self-efficacy, and job stress of childcare teachers for infants. This study also investigated whether the childcare teachers' supervision behaviors affected self-efficacy and job stress and whether their self-efficacy acted as a mediating effects on job stress and supervisory behaviors. The participants were 292 childcare teachers for infants in Seoul and Gyeonggi-do. The instruments utilized were the parent supervision attributes scale, Korean occupational stress scale, and teacher self-efficacy scale. The data analyzed by means of Pearson's correlation coefficients and hierarchical regression analysis. A hierarchical multiple regression analysis, Which Baron & Kenny first proposed, was conducted. The significance of the mediation effect was verified by the Sobel test. The results were as follows: First, the childcare teachers' supervision behaviors had a positive correlation with the teachers' self-efficacy, while the teachers' supervision behaviors and self-efficacy had a negative correlation with job stress. Second, job stress appeared to have a negative on supervision behaviors. Self-efficacy appeared to have a positive effect on supervision behaviors. Third, the mediating effect of self-efficacy was verified in the relationship between supervision behaviors and job stress. The more self-efficacy the childcare teachers had, the more supervision behaviors they performed. The greater their self-efficacy, the more the childcare teachers were able to control job stress. Therefore, by enhancing the self-efficacy of childcare teachers, their level of supervision behaviors should increase and their level of job stress should decrease.

This study was conducted to investigate how child-care teachers participate, practice mealtime instruction, and perceive difficulties in food service, focusing on comparison between the teachers caring two different age groups: children younger than three years (Younger Group) and those three years or older (Older Group). Questionnaires were distributed to 151 child-care centers in Kwanak-gu, Seoul, Korea during December, 2011. Only the data from 25 child-care centers, where two respective teachers in charge of Younger Group and Older Group completed the questionnaires, were analyzed. The results showed that there was no difference in terms of child-care teachers' participation in food service practice between the two groups, except for serving method; 'Pre-plated' serving was used significantly more often in Younger Group, whereas 'Line-up' serving was used in Older Group. Approximately, three quarters of the child-care centers had policies or guidelines on mealtime instruction. During mealtime, child-care teachers tended to use frequently verbal instructions such as "sit up straight when you eat" about eating manner, "don't be picky with your food" about eating habit, and "wash your hands before eating" about eating procedure in both the groups. There was no statistically significant difference regarding child-care teachers' perceived difficulties in food service between the two groups. These results indicated that child-care teachers' participation and mealtime instruction in food service did not differ between the two age groups, although children's development of digestion and eating skill differed by age. Therefore, training should be provided to child-care teachers about food service practices and mealtime instruction appropriate to children's age.

본 논문에서는 행동인식 기술을 기반으로 0세에서 2세까지의 아동을 대상으로 행동 발달 지표(활동성, 사회성, 위험성)를 파악하여 고도의 복지 서비스를 제공할 수 있는 시스템과 알고리즘에 관해 기술한다. 행동인식은 0세 영아의 눕기에서 부터 2세 유아의 점프까지 총 11개 행동을 대상으로 하였으며 광주·전남지역 어린이집 3개소에서 연구용으로 제공받은 실제 영상으로부터 직접 취득한 데이터를 학습에 사용하였다. 11개 행동에 대해 425개 클립 영상에서 1,867개 행동 데이터셋을 구축하여 학습한 결과 평균 97.4%의 인식정확도를 확인하였다. 또 실세계 적용을 위해 행동분석 장치인 엣지 비디오 분석기(Edge Video Analyzer, EVA)를 제작하였고 이 장치 위에 4채널 영상에서 최대 30명까지 실시간 행동인식이 가능한 영역별 랜덤 프레임 선택 기반 PoseC3D 알고리즘을 구현하였다. 개발된 시스템은 3곳의 어린이집에 설치되어 10명의 보육교사에 의해 1개월 간 실증테스트가 진행되었고 설문조사 결과 체감 정확도는 91점, 서비스 만족도는 94점으로 평가되었다.
