The jadeite powder has a disadvantage affecting the stability of the formulation due to the agglomeration of the powder when applied to cosmetic formulations. To overcome this problem, a new composite powder was prepared by modifying the surface of jadeite powder and applied to foundation pact and sun stick. In this study, a triethoxycaprylylsilane among various surface modifiers was selected as an optimum component, and applied to each formulation by making the jadeite powder composite. As a result, the foundation pact maintained the clarity of the product color, and the sun stick gave about 30% higher UV blocking effect in the UVB area compared with that of the blank. In the user sensory evaluation, the formulation containing the jadeite powder composite showed a high score for the overall indicator. The stability evaluation of the formulation was also confirmed that it was stable against discoloration, detachment and hardness. In conclusion, the jadeite powder composite is stable as an inorganic pigment which is applicable to cosmetics as a multifunctional material while maintaining the color clarity of the product and acting as a booster for sunscreen agents.

In this study, physicochemical properties of the natural jadeite powder were investigated and also the wash-off pack and liquid foundation containing the jadeite powder were prepared. In addition, each of these formulations was evaluated by various functional effects, sensory evaluation, stability and skin safety. In the wash-off pack, the far-infrared ray emissivity and radiation energy values increased as a function of the jadeite powder content. At a 3% jadeite powder content, the skin temperature increased by about $0.5^{\circ}C$ when the jadeite powder-containing formulation was applied to the skin. Besides, the chroma of the liquid foundation containing the jadeite powder more clearly expressed the original color of the skin. Moisture content measurements of the wash-off pack and liquid foundation containing the jadeite powder showed the highest moisture uptake of 5.0% and 63.0%, respectively. In sensorial test, the wash-off pack formulations containing the jadeite powder demonstrated improved affinities toward a skin, adherency, and moistness and combatted itching. The liquid foundation containing jadeite powder showed also improved affinities except for the coverage when compared to control formulations. Furthermore, the stability evaluation for 8 weeks revealed neither discoloration nor separation phenomenon for the formulations containing the jadeite powder. Moreover, the pH was found to be stable up to 8 weeks and the viscosity up to 4 weeks. Skin safety assessments showed that all formulations containing the jadeite powder were non-irritating. These results suggest that the jadeite powder as an inorganic pigment may serve as a new multi-functional cosmetic ingredient with stability and safety.

기존의 공정자동화 설비에서는 센서를 통하여 계측된 데이터들이 4-20mA의 아날로그 신호를 통하여 제어기와 컴퓨터들로 전송되었다. 이러한 아날로그 신호 전송 방식에서는 제어 시스템의 구조가 복잡해지고 설치에 많은 비용과 노력이 투입될 수밖에 없다. 이러한 문제점을 해소하기 위하여 기술 선진국에서는 필드 장비들 간에 고속의 직렬 통신을 통하여 제어 및 자동화 관련 디지털 데이터의 전송을 실시간으로 지원하는 필드버스 통신망을 개발하였으며, 1990년대 이후 공장 자동화, 공정 제어 및 발전 설비 등 각종 산업 설비에 필드버스를 매우 활발히 도입하고 있다. Foundation Fieldbus 모듈은 공정제어 시스템예서 사용되는 센서, 제어기, PLC, 밸브, 구동기, 스위치 등의 모든 필드 장비에 바로 탑재되어 Foundation Fieldbus의 통신 기능을 제공하는 통신 부품으로 첨단의 공정자동화 시스템을 구축하기 위하여 반드시 확보되어야 할 핵심기술이다. 본 연구를 통해 제작된 Foundation Fieldbus 모듈은 기존의 센서제품을 FF기반의 지능형 센서로 바로 전환할 수 있는 핵심부품이다.

In this paper, we propose an automatic cosmetic foundation recommendation system that suggests a good foundation product based on the user's skin color. The proposed system receives and preprocesses user images and detects skin color with OpenCV and machine learning algorithms. The system then compares the performance of the training model using XGBoost, Gradient Boost, Random Forest, and Adaptive Boost (AdaBoost), based on 550 datasets collected as essential bestsellers in the United States. Based on the comparison results, this paper implements a recommendation system using the highest performing machine learning model. As a result of the experiment, our system can effectively recommend a suitable skin color foundation. Thus, our system model is 98% accurate. Furthermore, our system can reduce the selection trials of foundations against the user's skin color. It can also save time in selecting foundations.

This study was conducted to investigate the relation between clothing pressure and subjective sensation exerted by foundation. Nineteen females volunteered as subjects. Experimental foundations were brassiere with 70B, 70C, 75B and 75C size which were widely distributed in pilot test and two types of girdle of which size were 64, 70 and 76. Clothing pressure with an air pack system and subjective sensation were measured at 5 points in brassiere and 7 points in the girdle. As the result of this study, brassiere's band and girdle's waist line, of which clothing pressure are high, is needed to improve. Generally the more pressure makes the more tightness, however, in some regions more or less pressure can give comfort. The tightness rating may not only related to clothing pressure, but also related to factors such as body size, body fat, resilience of muscle and bone structure. Other subjective sensation such as tactile feeling, hot/wet feeling, etc. in addition to the study with consideration of these factors could be used in future research to evaluate the effectiveness of foundation.
