본 논문은 최근 3D 프린터가 새로운 창작툴로 디자이너들에게 관심을 받고 있으나 수익창출과 연결될 수 있는 비즈니스 모델에 대한 정보는 부족하다는 판단 하에, 커스터마이징(customizing)된 제품의 소량생산이라는 3D 프린터의 강점을 활용, 기존의 대량생산 체제에서는 작은 시장규모로 인하여 연령에 따른 다양한 크기를 시장에 제공치 못하고 있는 현 미취학 유아동 선글라스 제품을 3D 프린터로 실제작, 소규모 비즈니스 모델로의 확장이 가능한 실질적 예를 제시하는 것에 연구의 목적이 있다. 이를 위해 3D 프린팅 기술에 대한 기본정보와 선글라스의 기본구조를 요약한 후, 시력교정용 안경사이즈표를 분석하여 유아동 선글라스 제작을 위한 사이즈표를 도출하고 일련의 작업들을 진행한 뒤, 최종적으로 실제품을 제작비용과 함께 제시, 본 연구의 결과가 시장에서 경쟁력 있는 제품으로서 소규모 비즈니스 모델로의 확장이 가능한 실질적 예가 될 수 있음을 확인하였다.

Recently rapid environmental changes due to desertification and industrialization in China make a threat to Korea, especially during Asian Dust Event (ADE). This study was aimed to compare symptoms and behaviors related to ADE between Korea and China. We conducted questionnaires on self-reported symptoms and behaviors before and during ADE. Korean and Chinese subjects were grouped into children, adults, and elderly by nation (n=791). Statistical analyses were performed by $X^2$-test, Fisher's exact test, t-test and chow's test for comparing differences between Korean and Chinese. We estimated the odds ratio for perceived symptoms during ADE by preventive behavior, using Generalized Estimation Equation (GEE). The study indicated that there were significant differences between symptoms in Korea and those in China such as cold, cough, and sore throat, especially in elderly. Preventive behaviors such as avoiding outdoor activity and wearing sunglasses were more often performed in China than Korea. However wearing mask was more often performed in Korea than China. After adjusting for age, sex, educational level, and smoking status, the odds ratio (OR) of dry cough symptom in Korea was significantly decreased by closing the windows and wearing a mask during ADE. In China, the OR of dry cough symptom was decreased by wearing a mask and avoiding outdoor activity. We found that China which had higher performance of preventive behavior showed lower prevalence of symptoms during ADE than Korea. Also preventive behaviors could affects prevalence of symptoms during ADE. This results suggest that preventive behavior. could reduce symptoms during ADE and there are needed for. more attentions to reduce a threat of ADE.
