IPTV 서비스는 기존 단방향 지상파 TV보다 다양한 채널의 다양한 콘텐츠를 제공하므로 사용자가 빠르고 쉽게 원하는 콘텐츠를 찾기 위한 개인화 IPTV 사용자 인터페이스 개발이 요구되고 있다. 하지만 기존의 연구는 단방향 TV 서비스 인터페이스를 그대로 이용하거나 단순 카테고리 별로 분류된 정보 제공에 머물러 개인화된 인터페이스로는 아직 미흡하다. 본 논문에서는 협력적 여과, 내용기반 여과 등 기존 개인화 추천 기법을 이용하여 사용자가 원하는 정보를 빠르게 제공하고, 사용자의 편의성을 증대하는 SmarTVi 인터페이스와 개인화된 검색 결과를 제공하는 검색 모듈 SmarTVi-Search를 제안한다.

The removal rates of pesticide residues on agricultural products by washing with tap water, washing with detergent, heating and dipping with ozonized water were analyzed. The removal rates of organophosphorous pesticide residues on perilla leaves and Korean cabbage were shown as 25.7-71.9% level by washing with tap water and 72.4%-82.0% level by washing with detergent. However, those on Angelica keiskei were shown as 44.6-64.7% level by washing with tap water and 72.4-82.0% by washing with detergent. Those on perilla leaves and Korean cabbage were shown as 61.1%-91.1% and 74.8-95.4% levels by heating, respectively. Also, the removal rates of organochlorine pesticide residues on perilla leaves and Aster scaber were shown as 55.6-66.3% level by washing with tap water, 85.8-93.0% level by washing with detergent and 54.1-63.6% level by heating. Therefore, the organochlorine pesticide residues was shown the highest removal rate by washing with detergent and not significance between washing with tap water and heating. When the grape was processed as jam, the removal rates of organophosphorous pesticide residues were shown as below 50% level and those of organochlorine were shown as 22.3-60.2% level with difference according to variety of pesticides. Also, the decomposition effects of pesticides by dipping in ozonized water were analyzed. The various solvents were tested for the most effective recovery of pesticides on agricultural products. The benzene contained 20% dichloromethane was shown the most effective recovery rate for organophosphorous pesticides as 105.4-113.8% level. Hexan was the most effective for organochlorine as 67.7-91.3% level. As the result by dipping with ozonized water, the changes of pesticide content levels according to dipping and dipping time in ozonized water were not shown significance.

This study was performed to reduce the pesticide residues from agricultural products. Some pesticides. dichlorovose, diazinon and methidathion, were applied to apple, pear, mandarin orange, cucumber and radish, then were washed with water and detergent, soaked with salt, and mixed with seasonings to determine the amount of pesticide residues. The removal rate of pesticide residue when agricultural products were washed with tab water were represented 24.11∼77.59% and the removal rate in vegetables were shown higher than that of fruits. The removal rate when washed with neutral detergent were showed 55.56∼91.26%, which values were showed higher removal rate around 20∼30% than that of washing with tab water, and dichlorovose and methidathion were easier removed than diazinone. When vegetables were pickled in salt, dichlorovose and methidathion were perfectly removed and diazinone was removed around 80%. When vegetables were fermented with seasoning such as garlic, green onion, the powder of capsicum and fish sauce for 5 days, most pesticide residues were perfectly removed. The pesticide residues were not detected after peeling of fruits.
