본 논문은 유아기 아이들에게 올바른 위생관리 습관 확립과 화장실 내 안전사고 예방을 도와주는 "Kids Self Care Mirror" 시스템을 제안한다. 제안하는 주요 기능은 다음과 같다. 첫째, 적외선/온습도 센서 등을 통해 실내 LED 및 환풍기 제어와 습도로 인한 미끄러움을 경고등과 경고음을 사용하여 방지한다. 둘째, 카메라 모듈을 사용하여 사용자를 인식하고 디스플레이를 통해 아이들을 위한 양치 교육 동영상을 재생시킬뿐만 아니라 치아 상태에 따른 치약을 추천한다. 또한 액체비누 디스펜서 버튼을 누르면 손 씻기 교육 동영상이 재생된다. 셋째, 액추에이터를 사용하여 사용자의 키에 맞게 거울의 높낮이를 자동으로 조절한다. IoT 기술과 OpenCV, 치아 관리 알고리즘을 활용한 "Kids Self Care Mirror" 시스템을 통해 아이들에게 발생할 수 있는 각종 질병과 사고를 방지할 수 있을 것으로 기대된다.

In order to obtain efficient control effect of the pesticide, it is important to ensure uniform adhesion to the desired plant parts at the right time. Pesticide spray method (application technology) is an important factor affecting the efficacy and crops persistent expression. The aim of this study was to develop an efficient system to investigate the coating weight distribution of citrus leaves due to the difference between the nozzle and spray sprinkler system using dithianon used in citrus scab. Other An, engine type sprayer was used as the control. Speed sprayer and different sprinklers were wsed to way the deposit amounts of dithianon on citrus leaves. The test was conducted at the National Institute of Horticultural Herbal Science Citrus Research Station, located in the circle citrus Jeju Island. In order to examine whether the citrus orchard spray and the evenl on the whole, dithianon (43% flowable 1000-fold dilution) was sprayed, filter paper and leaves were analyzed by the height as top, middle, bottom. Speed sprayer the was most effective on depositing at the middle position, of the leaves. All other sprays the leaces except the dry mist sprinkler were not effective enough to deposit on the back sides. To achieve more deposits on the high position leaves, an improve ment in the nozzle and an efficient power system of sprayer were needed.
