This study has been designed to stress the thoughts that soups should be offered taking into account customer's preference aimed at leading to eventual customer's satisfaction and the importance that Korean traditional food should take the lead in shifting dining-out industry's paradigm to customer-orientation instead of product-orientation. From August 15 through August 30, 2003, the drawn-up questionnaires were handed out to 500 numbers of adults aged over 20 living in Seoul, metropolitan city of Korea and the finally collected 361 questionnaires from them have been analysed as a subject for this study. It showed that the male respondents(44%) dined out much more frequently than the female respondents(35%) and their rate of 5,000-7,000 Won for a meal was most preferred as their average expenditure at one sitting in the restaurant. When eating Korean food at home or in a restaurant, the majority(5l,3%) of them think the soups(Tang) should be served coupled with their ordered meals. Among soups using flesh and meat as a staple material, they most preferred beef & bone soup(33.2%), followed by beep rib soup(30.4%) and beef soup with seasoned red pepper(l0.8%), and among soups using fish & shell and crustacean as a staple material, most preferred were hot fish soup(20.6%), loach soup(l5.2%) and hot crab soup(11.4%). Among soups using beans as a staple material, they most preferred soybean paste stew(33.2%), uncurdled soybean curd stew(29.4%) and Dambuk stew(l5.8%). Among soups using fowls and birds as a staple material, chicken soup with ginseng(51.9%), plain chicken soup(l8.4%) and chicken soup with red pepper sauce(l2.3%) falls on the most preferred. Among soups using vegetables and seaweeds as a staple material, most preferred are sea mustard soup(25.3%), Kimchi soup(16.8%), soybean paste soup with Chinese cabbage(13.0%) and bean sprout soup(10.1%). The soups(Tang) most preferred in the morning time are those soups whose staple materials are vegetables and seaweeds, such as sea mustard soup, bean sprout soup, Kimchi soup and soybean paste soup with Chinese cabbage while the soups most preferred for the lunch time are beef & bone soup, beep rib soup, chicken soup with ginseng and beef soup with seasoned red pepper while beef soup with seasoned red pepper, beef & bone soup, soybean curd stew and Kimchi soup are most preferred soups for the dinner time. The survey showed that 41 % of the subject preferred chicken soup with ginseng for a food considered good by themselves for their health. The male respondents preferred Bosin-tang(soup of edible-dog meat) than the female counterparts did, while the female respondents preferred chicken soup with ginseng than the male counterparts did. The survey showed that when eating korean traditional food, 70% of the subject are visiting a restaurant where soups are cooked delicious while 61% of the subject think that price does not matter if only food tastes good, which is reflecting that taste of food is a decisive factor in selecting menu rather than its price is. In conclusion, you can say that taste of soup is the most important factor creating steady customer in the restaurant, taking it into account Korean people most prefer their traditional food when dining out.

In this study, 419 students of the 6th grade in three schools in Masan were surveyed. The students having less than 24 items among 48 protein-rich foods easily obtained were considered as unbalanced-diet students. Their general circumstances, character, status of growth and development and school performance were compared with those of balanced-diet students. The results were following. 1. The actual condition of unbalanced diets of protein-rich food 1) Female showed high degree of unbalanced diet in meat food while male in shell-food. Both sexes liked processed food stuffs such as ham, sausage and boiled fish paste but not salted. Both of them disliked beans. 2) The reason for unbalanced diet, they answered, was bad taste and smell of some foods. The reason, their mothers amswered, was they fed their children some particualr foods. 3) The attitudes of the mothers against unbalanced diets were coaxing their children to eat some foods for they are good for health or forcing their children to eat some foods. The most effective method on the children was coaxing and the next was changing cuisines. 2. The general circumstances of the students. 1) 168 students (male: 85, female:83) among 419 students who were studied were unbalanced-diet students and the extent of unbalanced diet was similar in both sexes. 2) The rate of unbalanced-diet students was higher among the students who were the first child in the family, had a small family or were fed milk or mixed milk. 3) The school career of unbalanced-diet student's mothers was higher and the rate of unbalanced-diet students was higher among the students who have rich families or career mothers. 3. The status of physical condition 1) The height and weight of unbalanced-diet students were lower than those of the standard of Korean children. The status of balanced-diet students were better than that of the standard. 4. Degree of school performance 1) The school records of unbalanced-diet students was 81.4 points in average, which was 1.3 points lower than the average of city students and that of balanced-diet students was 2.8 points higher than average. There was a significant gap between the two groups. 5. The relation between unbalanced diet and character 1) Compared balanced-diet students, unbalanced-diet students showed high degree of nervousness and coldheartedness and low degree of self-reliance and self-possession. There was a significant gap between the two groups and it showed that unbalanced diets affected the formation of character.

전 세계적으로 커피 시장이 매년 커지고 있고 이에 따라 커피 포장지의 수요 역시 증가하고 있지만 제품에 직접적으로 접촉하게 될 씰란트 층에 사용되는 PE 재질과 PP 재질이 커피 향에 미치는 영향에 대한 연구는 부족한 실태이다. 본 연구에서는 전자코(Electronic nose)와 기체크로마토그래피와 질량분석기(GC/MS)를 이용하여, PP와 PE 재질의 파우치에 커피를 담아 향기 패턴과 향 물질의 변화를 연구해 보았다. 저장기간에 따른 휘발성분 분석 결과, 커피의 향기 성분 분석에 적합한 지표 물질은 pyridine이었다. 추가적으로 온도($4^{\circ}C$, $25^{\circ}C$ and $40^{\circ}C$)와 탈산소제의 유무에 따른 향기 패턴 변화 역시 관찰하였다. 그 결과, 미미하게나마 PP계열 포장재가 PE계열 포장재보다 보향성이 좋았으나 재질에 의한 성능의 변화는 거의 없다는 결과를 얻었다. 오히려 재질보다는 온도에 의한 향기 패턴 변화가 지배적이었다. 냉장 유통($4^{\circ}C$)이 가장 좋은 보관 온도였고 짧은 기간 내에 판매가 이루어지는 것이 이상적이다.

This study evaluated the quality characteristics, the presence of polyphenolic compounds, and radical scavenging activity of rice cooked along with various mixed grains (barley, black soybean, adzuki beans, foxtail millet, proso millet, sorghum, glutinous rice) by following two different cooking methods (normal and pressure cooker). The amylogram and water characteristics of mixed grains showed significant differences based on the presence of different types of mixed grains. The chromaticity, palatability characteristics, presence of phenol compounds, and radical scavenging activity of rice cooked along with different mixed grains showed significant differences according to the nature of mixed grains. Total polyphenol contents of before cooking, cooked-rice added to mixed grains cooked in the normal cooker and a pressure cooker were 4.46~5.16, 0.58~0.93 and 0.65~0.96 mg GAE/g, and total flavonoid contents were 250.74~548.89, 129.26~207.04 and $127.41{\sim}218.15{\mu}g\;CE/g$, respectively. The DPPH radical scavenging activity of before cooking, cooked-rice added to mixed grains cooked in the normal cooker and a pressure cooker was 79.25~181.61, 22.07~53.64 and 7.51~39.97 mg TE/100 g, and ABTS radical scavenging activity was 203.25~328.24, 47.28~84.94 and 58.27~99.51 mg TE/100 g, respectively. Accordingly, it is necessary to different combinations of mixed grains according to the cooking method at home and grain industry.

The proximate compositions, quality and physicochemical characteristics of mung-bean cultivars cultivated in the north-central region of South Korea with different seeding periods were evaluated. A significant difference was noted in the proximate compositions and chromaticity of mung-beans according to cultivars and different seeding periods. Crude ash and protein content decreased with the delay in seeding period and a slight increase in carbohydrate content was observed. Redness of the other five cultivars increased with the delay in seeding period except for the cultivar Jangan, while the yellowness decreased in cultivars Geumsung and Jangan. Water binding capacity of the $1^{st}$, $2^{nd}$ and $3^{rd}$ seeding on the cultivar Eoul was 115.15, 99.76 and 96.31%, respectively, and a decrease in the binding capacity was observed with the delay in seeding periods. Water solubility index and swelling power were significantly different among cultivars. Total polyphenol content of $1^{st}$ and $2^{nd}$ seeding on the cultivar Jangan was 8.59 and 8.57 mg GAE/g, respectively, and a decrease was observed with the delay in seeding periods except for the cultivar Sohyeon. Total flavonoid content of $1^{st}$ seeding on the cultivar Jangan was 5.25 mg CE/g, which decreased with the delay in seeding periods. DPPH radical scavenging activity of $1^{st}$ seeding on the cultivars Geumsung and Kyungseon was 2.44 and 2.32 mg TE/g, respectively, which decreased with the delay in seeding periods. The BTS radical scavenging activity of $1^{st}$ seeding on the cultivar Jangan was 6.98 mg TE/g. In the present study, the variations in phenol content and radical scavenging activity were observed to be dependent on the cultivars and seeding periods.

Faba beans (vicia faba) (FB) and lupin seeds (Lupinus Albus) (LS) were dry roasted at three temperatures (110, 130, $150^{\circ}C$) for 15, 30 or 45 min to determine the effects of dry roasting on rumen degradation of crude protein and starch free organic matter ($^{PSF}OM$). Rumen degradation characteristics of $^{PSF}OM$ were determined by the nylon bag incubation technique in dairy cows fed 60% hay and 40% concentrate. Measured characteristics of $^{PSF}OM$ were undegradable fraction (U), degradable fraction (D), soluble fraction (S), lag time (T0), and the rate of degradation (Kd). Based on the measured characteristics, rumen availability ($RA^{PSF}OM$) and bypass $^{PSF}OM$ ($B^{PSF}OM$) were calculated. Dry roasting did not have a greater impact on rumen degradation characteristics of $^{PSF}OM$ (p>0.05). S varied from 32.1 (raw) to 30.0, 27.8, 30.8% (LS) and 15.4 (raw) to 14.4, 20.8, 20.9% (FB); D varied from 65.4 (raw) to 66.3, 66.9, 55.9% (LS) and 54.9 (raw) to 55.0, 51.0, 64.7% (FB); U varied from 2.6 (raw) to 7.3, 7.0, 7.7% (LS) and 29.7 (raw) to 30.6, 28.2, 14.4% (FB); Kd varied from 6.0 (raw) to 7.3, 7.0, 7.7% (LS) and 22.4 (raw) to 24.4, 21.1, 7.9% (FB); $B^{PSF}OM$ varied from 35.5 (raw) to 33.8, 36.6, 38.2% (LS) and 41.3 (raw) to 41.5, 39.7, 47.6% (FB) at 110, 130 and $150^{\circ}C$, respectively. Therefore dry roasting did not significantly affect $RA^{PSF}OM$, which were 353.7, 367.9, 349.6, 336.9 (g/kg DM) (LS) and 12.82, 127.0, 133.7, 117.1 (g/kg DM) (FB) at 110, 130 and $150^{\circ}C$, respectively. These results alone with our previously published reports indicate dry roasting had the differently affected pattern of rumen degradation characteristics of various components in LS and FB. It strongly increased bypass crude protein (BCP) and moderately increased starch (BST) with increasing temperature and time but least affected $^{PSF}OM$. Such desirable degradation patterns in dry roasted LS and FB might be beneficial to the high yielding cows which could use more dry roasted $^{PSF}OM$ as an energy source for microbial protein synthesized in the rumen and absorb more amino acids and glucose in the small intestine.
