  • Chemical characteristics of soybean oil after deep-frying with potato sticks (200 g, 10% w/w of soybean oil) were studied according to the 34 deep-frying times. After consecutive 34 deep-frying, total polyunsaturated FA contents was gradually decreased while the total saturated FA and trans FA were increased. Acid value and peroxide value were increased while iodine value decreased, respectively. The Hunter $L^{\ast}$ value decreased while each $a^{\ast}\;and \;b^{\ast}b$ value were gradually increased. Electronic nose equipped with 12 metal oxide sensors was used for the discrimination of odor pattern of frying oils against the times of deep-trying. The proportions of 1st and 2nd principal component analysis showed 75.97% and 21.23%, respectively. While 6 among total 12 sensors well responded to discrimination of odor in the repented frying oils, suggesting that the odor pattern of each oil after deep-frying would be discriminated against fresh soybean oil, especially after 14 times. From the results, electronic nose could differentiate the degree of quality deterioration of the repeated deep-frying oils.

  • Flavor is one of the most important factors for determining wine characteristics and quality. Flavor pattern of wines(brewed from America, France, Italy, Chile, and Australia) was analyzed by the electronic nose that is equipped with 12 metal oxide sensors. In the results, the flavor pattern of wines was discriminated according to their origins by the principal component analysis(PCA). Each proportion of the first principal component score in the PCA plot was 94.79%(America), 73.62%(France), 99.06%(Italy), 96.74%(Chile), and 96.53%(Australia), respectively. Consequently, the imported wines could be practically differentiated into one from the other origins by volatile properties, suggesting that electronic nose could be successfully used for easy screening and quality evaluation of wines.

  • The purpose of this paper was to clarify the actual conditions of the 'Dietary externalization' mainly by using the economic and nutrition-related data, accompanied by the economic development in Korea and Japan. 'Modernization of food style' and other modernization have taken place, among which 'Dietary externalization' in particular has recently drawn interest. At the time this paper clarified with econometric analysis whether there are differences between the two countries in term of the modernization of food style and dietary externalization trend. The trends of Dietary externalization of both Korea and Japan were studied using Principal Component Analysis method. The food subgroup were investigated based on the annual report on the household income and expenditure survey of Korea and the annual report on the family income and expenditure survey of Japan. The statistical data from both country were analyzed by SAS program. The results are as follows; 1. In Korea, the ratio of carbohydrates in the total calorie intake is quite high and animal protein is rather low compared to those in Japan. 2. Traditional food such as grains and vegetables are consumed much more in Korea than in Japan. 3. The Principal Component 1, 2 were extracted in both countries during the whole analysis period, which suggested the 'Dietary externalization' 4. Principal Component 1 has a positive factor loaded in all food items including meals outside the home and process food. In other words, it is apparent that the 'Dietary externalization' tread in Korea has a simple pattern suggesting that all externalization related items are on the rise. 5. Principal component 1, 2 which indicated the dietary externalization, were detected in Japan.

  • 지난 1세기 동안의 한국인 식사 습관의 변화를 조사 분석한 결과는 아래와 같이 요약된다. (1) 이조 말기까지 한국인은 다양한 곡류, 채소류, 과실류를 식품으로 이용하였으나 농업의 전문화와 생활 방식의 도시화에 의하여 이들 식품 재료의 종류가 크게 감소하였다. (2) 우리의 전통식단은 영양적으로 균형잡힌 구성을 가지고 있었으나 일제의 수탈과 전쟁 중의 식량난으로 한국인의 영양 섭취는 크게 악화되었다. (3) 전쟁 중 악화된 영양상태를 전통 식사법의 회복으로 극복하려 하지 않고 서양식 식사법의 도입으로 해결하려 하였다. (4) 전쟁중의 기아 상태에서 외국 원조로 공급된 분유와 밀가루의 섭취가 일반화 되었으며, 전후 경제 개발 과정에서 분식 장려 정책과 축산 진흥 정책이 계속되었다. (5) 1970년대 이후의 경제 성장 과정에서 식용 및 사료용 곡물 도입이 급증하게 되었으며 식량 자급율은 50% 이하로 하락하였다. (6) 1970년대에 와서야 우리의 식량공급은 이조 말기의 수준으로 회복되었다. 그러나 그 구성면에서 지방질의 섭취가 크게 증가되는 양상을 나타내었다. (7) 1980년대에는 동물성 식품의 소비 과다, 지방의 과잉섭취 현상이 계속 심화되고 있으며 이러한 현상은 성인병의 발병율 증가 등 국민 보건의 퇴화 조짐과 식량 수입에 따른 경제적 부담을 가중시키고 있다. (8) 우리의 전통 식사법에 근거를 둔 식사목표의 설정과 올바른 식습관 정립을 위한 국민 교육과 정책적 배려가 시급히 요구되고 있다.

  • The purpose of this study is to investigate the importance of well-being related to lifestyle choices such as food habits, food choices, life pattern, etc. The survey was conducted among college students using a questionnaire and a 5-point Likert score in Seoul City and Kyunggido Province during September 2005. The responses of 968 college students were analyzed by the SPSS program. The results were as follows. Most of the subjects were female(76.2%), and lived with their parents (85.6%). The average score of 'food habits', 'choosing food materials', 'purchasing' and 'life pattern' were $2.71{\pm}1.22,\;2.86{\pm}1.28,\;2.41{\pm}1.21,\;and\;2.97{\pm}1.31$ respectively in males and $3.01{\pm}1.20,\;3.00{\pm}1.32,\;2.55{\pm}1.20,and\;2.68{\pm}1.40$ in females, respectively. In regard to 'food habits', the scores were significantly affected by gender(p<0.001), smoking(p<0.05), alcohol consumption(p<0.05), exercise(p<0.001), weight satisfaction(p<0.001), method of weight control(p<0.001), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001), and whether the individual tried a well-being item(p<0.001). In regarding to 'choosing food materials' the scores were significantly affected by gender(p<0.001), smoking(p<0.05), exercise(p<0.001), weight satisfaction(p<0.05), method of weight control(p<0.05), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001) ), and whether the individual tried a well-being item(p<0.001). Out of the factors affecting 'purchasing', the association with BMI was remarkable. Students who were overweight, obese or underweight showed higher average scores than students of normal weight. The primary concerns and trial of well-being of college students were food and exercise. Therefore, the purchase of well-being goods is related to their weight control in college students. In regard to 'life pattern' the scores were significantly affected by exercise(p<0.01), use of computer(p<0.001), BMI(p<0.001), weight control(p<0.001), use of nutritional supplement(p<0.05), regularity of breakfast(p<0.001), level of interest in wellbeing(p<0.001), whether the individual tried a well-being item(p<0.001), and having taken lecture on well-being(p<0.05). Therefore nutrition education is needed for healthy eating habits of college students and it is necessary to develop a series of lectures to teach them about diet and exercise programs.

  • 본 연구는 여대생의 생활패턴이 월경곤란증에 미치는 영향 요인을 파악하여 생활패턴의 변화를 통한 건강관리 프로그램 개발의 기초자료를 제공하기 위한 서술적 조사연구이다. 대상자는 2019년 11월 18일-29일까지 총 2주 동안 C도 J대학교에 재학 중인 여자 대학생 중 월경곤란증이 있는 자를 대상으로 총 133부의 자료를 수집하여 분석하였다. 연구결과, 월경곤란증과 일반적 식습관(r=-.441, p<.001)과는 통계적으로 유의한 수준에서 보통의 역상관관계를, 나트륨 식행동(r=-.214, p=.013)과는 약한 역 상관관계를 보였다. 월경곤란증에 미치는 영향 요인은 일반적 식습관(β=-.457)이 가장 높은 영향을 주는 요인으로 나타났으며 그 다음은 흡연(β=.175), 음성통화(2시간 초과)(β=.163) 순으로, 전체 설명력은 29.3%로 나타났다. 따라서 여대생의 월경곤란증을 완화하기 위하여 교육과 홍보를 통해 긍정적인 식습관, 금연생활 및 스마트폰 음성통화시간은 2시간 이내로 사용 할 것을 권장하는 등의 건강한 생활패턴으로의 변화를 유도해야 할 것이다.

Newspaper articles on home cooking in Cho-Sun Daily Newspaper, published from 1961 to 1993, were analyzed, and the results are summerized as follows: (1) Total number of articles on home cooking was 817. Traditional Korean foods had been introduced more often than foreign foods, particularily after the third period($'79{\sim}'93$). In the first period($'61{\sim}'67$ serving size of 5 had been adapted mainly, whereas serving size of 4 had been adapted more frequently after third period. (2) Vegetable foods were the most frequently introduced item in home cooking articles as a whole. In the third and forth periods starch foods had been reduced, whereas vegetable and meat foods had been increased in home cooking articles. Use of foods of the season had been reduced thanks to spreading of greenhouse and to improvement of food storage technology. (3) Traditional Korean foods were largely composed of kimchi, boiled rice, Korean style soup and stew which are basic foods in Korea. Foreign foods introduced were mainly beverage, alcoholic drink and salad. Since 1980 meat, chicken and vegetable dishes had been frequently introduced. In conclusion, the daily newspaper articles on home cooking reflect the changes in Koreans' food consumption pattern and consciousness of dietary life.
