본 논문에서는 마커와 제스처 인식을 통한 유아교육용 로봇을 개발하였다. AR 마커는 사물의 영어 단어 맞추기, QR 코드는 AR 마커에서 인식된 단어에 해당하는 사물 그림의 퍼즐 맞추기 등을 통하여 유아의 지각 능력을 향상시키게 하였다. 제스처 인식은 유아가 직접 알파벳 모양의 그림을 손으로 그리면서 알파벳이 어려운 글씨가 아닌 그림으로 인지하게 하여 영어에 대한 거리감을 좁힘으로써 단순히 시각 위주의 교육 방법이 아닌 몸으로 하는 흥미위주의 교육 콘텐츠를 개발하였다. 또한 위치인식 기술을 사용하여 특정 명령에 따라 로봇이 이동한 후 초기 위치로 복귀할 수 있도록 하여 유아의 시선에서 이탈하지 않도록 하였다. This paper presents the development of an early childhood education robot using gesture recognition and image processing. To enhance cognitive ability, AR markers are adopted in English words matching and QR codes are used in jigsaw puzzles for an object recognized from AR markers. By drawing a picture of alphabets on the air using one hand and utilizing gesture recognition techniques, the alphabets can be considered as a picture, not a difficult text, and children can be closer to English. Based on this approach, we developed attractive education contents using body opposed to multimedia education. In addition, our robot can return to the initial position after movement according to a specific command, and therefore can stay in the area of children's view.

Objectives This study was conducted to investigate the beta-glucan & ginsenoside content, antioxidant activity, anti-inflammatory effect and safety of herbal medicine mix. Methods The marker compounds contents, antioxidant activity and safety of herbal medicine mix were tested. The contents of beta-glucan and ginsenoside Rg3 were measured, the antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, anti-inflammatory and a safety test was conducted via single dose toxicity assessment. Results Analyzing the contents of marker compounds showed 362.3 mg/g of beta- glucan, and 0.4184 mg/g of ginsenoside Rg3. In the DPPH free radical scavenging activity, the IC50 of herbal medicine mix, was 0.146%. The scavenging activity of herbal medicine mix was 88.28% activity at 0.5% concentration, and 90.61% activity at 5% concentration. In the lipopolysaccharides (LPS) anti-inflammatory test, the herbal remix showed a significant decrease in tumor necrosis factor-alpha (TNF-α) and interleukin- 6 (IL-6) compared to the LPS-induced group. In the single dose toxicity test of herbal medicine mix, a dose of 2,000 mg/kg body weight (BW) was set at its highest capacity and observed after oral administration to female and male rats. No toxicological findings were recognized. It was observed that the resulting lethal dose can be set to 2,000 mg/kg BW or higher for both females and males. Conclusions The results of the experiment on herbal medicine mix showed that the marker compounds contents were beta-glucan and ginsenoside Rg3, that antioxidant activity was observed through the DPPH free radical scavenging activity, anti-inflammatory effect was observed through TNF-α and IL-6 measurement, and safety was confirmed through the single dose toxicity assessment.
