  • This study was conducted to develop a Han-sik database as well as to assess the effects of Han-sik on dietary quality among Koreans. The Han-sik database was developed by a focus group composed of food and nutrition specialists considering the results of Han-sik perception surveys conducted in previous studies for frequently consumed dishes. Among the 1,322 dish items identified in the $4^{th}$ (2007-2009) Korea National Health and Nutrition Examination Survey (KNHANES), 973 items (73.6%) were classified as Han-sik. Han-sik usage was defined as the percentage of Han-sik items of all individually consumed dish items in the dietary data of 22,113 subjects who participated in a 24-hour diet recall in the $4^{th}$ (2007-2009) KNHANES. Dietary quality was evaluated based on adherence to the Korean Food Guidance System (KFGS), which was calculated as the percentage of the number of servings consumed in each food group out of recommended servings according to age and sex. Mean usage of Han-sik was 80.1% and was higher in older age groups, rural areas, as well as in households at the lowest income level. Han-sik usage was also higher on weekdays as well as for breakfast. Adherence to the KFGS was significantly higher for grains, meat fish egg beans, vegetables, and fruits (p<0.001) but lower for milk dairy products and oils fats sugars (p<0.001) across the quartiles of Han-sik usage. The results of this study indicate that Han-sik usage is high among Koreans. Further studies are needed to update the Han-sik database as well as investigate the association between health-related factors and Han-sik use.

  • 본 연구는 탐지 대상물체의 형상인식이 가능한 비접촉, 원격 탐지장치의 개발에 관한 것이다. 형체인식용 비접촉 시스템은 주로 Magneto- lmpedance법과 Magneto-Inductance법이 있으며, Magneto-Inductance법은 왜곡이 적고, 인체나 탐지 대상물체에 손상을 가져오지 않는다. 본 연구에서는 2극으로 디자인 된 Magnetic Tomography System을 이용하여 물체의 위치에 따른 투자율 변화량을 계산 및 실측하였다.

  • 본 연구는 탐지대상물체의 형상인식이 가능한 비접촉, 원격 탐지장치의 개발에 관한 것이다. 본 연구에서는 2극 또는 4극의 정자기장을 인가할 때 탐지 대상 물체에 의한 자기장의 자계외곡을 32개의 Hall Sensor로 감지하여 탐지 대상 물체를 인식하는 원격 감지 System을 설계하였다. 투자율에 따른 민감도는 10 이하에서 우수한 특성을 보였고 위치에 따른 민감도는 2극에서는 어느곳에 있어도 특성이 좋았고 4극에서는 중심에서는 특성이 좋지 않으나 물체가 센서 가까이에 있을 때 특성이 좋았다.
