국화과(Compositae) 다년생 초본인 산국속(Dendranthema)은 국내 약 13여종이 자생하는 것으로 알려져 있으며, 이 중 감국(D. indicum (L.) Des Moul.)과 산국(D. boreale (Makino) Ling ex Kitam.), 구절초(D. zawadskii var. latilobum (Maxim.) Kitam.)가 주로 차 또는 한약재 등의 원료로 이용되고 있다. 차로 이용되는 꽃은 산국이 감국에 비해 상대적으로 작아서 구분이 가능하지만 시중에는 건조된 형태로 가공 유통되므로 육안으로 구분이 쉽지 않고, 산국 유래 제품들은 국내에서 감국 또는 국화로 혼용해서 표기되어 유통되고 있어 그 기원을 명확히 정립할 필요가 있다. 이에 본 연구는 감국과 산국의 분자유전학적 판별을 위해 DNA 바코드 후보 유전자를 활용하여 염기서열분석으로 확보된 SNP 및 InDel 정보를 바탕으로 CAPS 마커를 개발하고자 수행되었다. 감국과 산국 모두 trnL-trnF intergenic spacer 구간에서 약 1kb의 PCR 산물이 확인되었고, 이들 염기서열에서 분석한 2 SNP 및 3 InDel을 대상으로 CAPS 마커 개발을 위한 제한효소 사이트를 탐색하였다. Gap을 포함한 774bp (감국/산국=A/G) 위치의 SNP에서 BstUI(GC^GC)처리로 CAPS 마커로 전환 가능함이 확인되었고, 이에 감국과 산국의 PCR 산물에 제한효소를 처리한 결과, 제한효소 인식 사이트가 존재하는 산국에서 두 개의 DNA 단편이 확인되었다. 위 결과는 다양한 형태로 가공 유통되는 감국과 산국의 판별을 위한 마커로 활용될 수 있으며, 본 연구에 활용된 기술은 추후 건강기능식품 개발을 위한 원료표준화 확립 연구에 유용할 것으로 판단된다.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. Thus, design, comfort and economical efficiency are important factors of shoes. Consumers can choose suitable shoes for their feet in off-line shopping. However, in on-line shopping, because they can not wear shoes, compare to the off-line shopping, there are many problems in internet shopping. First, consumers can get limited information of shoes because they must search information of purchase without other's help. Second, because consumers can not get important information such as design, size and a comfort of wearing, they can not make a careful decision. Above these, the solution of user-oriented internet shopping is development of new type of prototype which is accessible to user and to offer visual information through 3D virtual reality.

This study was performed to develop menu satisfaction index in Business & Industry (B&I) food service and to survey customer's menu satisfaction using the index. The menu satisfaction index included 16 items with Likert 5 point. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8917, which indicated highly reliable. Construct validity was assessed by principal components analysis and then four factors explaining 65.964% of the total variance were found. Among the 15 items of menu satisfaction, the average scores of all items were above 3.0 out of 5. As a result of analysis on menu satisfaction factors, 'propriety of food temperature' (3.52 out of 5) was the highest consideration followed by 'sufficiency of format' (3.46), 'excellence in food' (3.35) and 'well-being orientation' (3.31). It could be said that customer's perception on the menu quality was very positive. Four factors were correlated with overall menu satisfaction positively. Especially, 'excellence in food', and 'well-being orientation' and 'sufficiency of format' affected significantly on overall menu satisfaction. It concluded that customers were satisfied with portion size, temperature, price but their needs for taste and health/nutrition-related service would be increased. The menu satisfaction developed in this study should be applied to other B & I food service operation by type.
