  • 입력신호인 도로표면의 화상 데이터는 낮 시간대의 아스팔트 포장 도로면을 촬영하여 도로표면 상태의 화상을 만들었고, 편광 및 웨이블릿 변화(Wavelet transform)으로 도로 표면을 5가지의 상태(건조, 습윤, 수막, 적설, 동결)로 인식할 수 있는 분류기준절차를 연구하였다. 표면 화상 인식 과정은 편광계수에 의한 젖은 땅으로 분류한 후, 다음으로 젖은 땅을 제외한 나머지는 웨이블릿 패킷 변환을 통해 시간-주파수 분석을 하였다. 또한 영상 템플릿을 이용하여 마른 땅과 빙판의 표준적인 주파수 특성을 분석하여, 마른 땅과 빙판을 구분하였다. 도로표면영상에서 마른 부분과 젖은 부분을 구분한 결과를 정리하였다.

  • Psychogenic cough is barky, croupy, and explosive and disappears during sleep, and is not affected by antitussive drugs. Physical and radiological examinations of the respiratory tract and other routine laboratory test are normal. It is helpful to recognize this condition early in its course so that appropriate treatment can be instituted before iatrogenic problems resulting in multiple hospitalizations and chronic steroid use occur. We experienced two child and adolescent cases that showing typical psychogenic cough so reported it with the literatures review.

  • Recently, many studies have been conducted on the changing phenology on the Korean Peninsula due to global warming. However, because of the geographical characteristics, research on plant season in autumn, which is difficult to measure compared to spring season, is insufficient. In this study, all leaves that maple and fallen leaves were defined as 'Decay leaves' and decay leaf detection was performed based on the Landsat-8 satellite image. The first threshold value of decay leaves was calculated by using NDVI and the secondary threshold value of decay leaves was calculated using by NDWI and the difference of spectral characteristics with green leaves. POD, FAR values were used to verify accuracy of the dry leaf detection algorithm in this study, and the results showed high accuracy with POD of 98.619 and FAR of 1.203.

  • To investigate the change of fatty acid content during processing and storage of seafood, the fatty acid contents of 5 kinds of boiled-dried anchovies from the market were quantified using tricosanoic acid (23:0) as an internal standard material. Crude lipid contents of boiled-dried anchovies from the market were $16.9\%$ (Dae-myul), $12.5\%$ (Joong-myul), $9.5\%$ (So-myul), $8.7\%$ (Ja-myul) and $7.6\%$ (Se-myul). Acid value, peroxide value and carbonyl value of boiled-dried anchovies were $14.9{\sim}20.1,\;22.4{\sim}89.8meq/kg$ lipid, and $14.7{\sim}49.6meq/kg$ lipid, respectively. These values were increased as the sample size increased. Total fatty acid content of boiled-dried anchovies were 562.8 (Dae-myul), 572.2 (Joong-myul), 542.8 (So-myul), 587.7 (Ja-myul) and 568.8 (Se-myul) mg/g as 23:0. There was an increasing tendency in the content of 16:0, 16:1 and 18:1, but a decreasing tendency in polyenoic acids such as 20:5 and 22:6 according as the specimen size increased. The major fatty acids of boiled-dried anchovies were 16:0, 16:1, 22:6, 18:1, 20:5 and 14:0.

  • In the processing of the bailed-dried anchovy treated with BHA, caught in Chinhae Bay in Korea, the most suitable concentration of BHA was 5/10,000 (the concentration of BHA to the curing solution; g/cc). Although the concentration of BHA is high than mat of BHA 5/10,000, the effect of protection from deterioration due to the oxidation of oil did not increase. Boiled-dried anchovy treated with the concentration of BHA 5/10,000 could preserve for nine months unless the quality does not loss value of food.
