Food is an essential component of good health and a high quality of life. This is especially true for the elderly, where health and quality of life can vary due to eating issues. This study attempts to measure the satisfaction with food-related life in the elderly of South Korea, while examining differences in social support, depression, isolation, and life satisfaction based on the level of satisfaction with food-related life. Data collection was conducted using one-on-one surveys from December 2011 to January 2012. A total of 390 elderly (aged 65 and over) who live in Korea participated in this study. The results showed that the satisfaction with food-related life was high (3.52 out of 5). The elderly who had company during a meal or a meal preparer showed a higher satisfaction with their food-related life. Social support was high (5.32 out of 7) and the feelings of isolation were low (3.85 out of 5). The average satisfaction with life was 4.42 out of 7, indicating a fair satisfaction with life, while the average depression score was relatively low (8.77 out of 26). In general, the elderly with a higher satisfaction with food-related life had a higher social support and overall satisfaction with their life. On the other hand, the elderly with a lower satisfaction with food-related life generally reported higher levels of depression and isolation. A positive correlation was observed between satisfaction with food-related life, social support, and satisfaction of life, while a negative correlation was found between satisfaction with food-related life, isolation, and depression. The results of this study indicate that managing the satisfaction with food-related life is an important component of mental health in the elderly.

This study investigates the impact of International Monetary Fund(IMF) Age on the household behavior of food consumption and analysis the related factors(demographic variables, family life style) to find out the reasonable consumer's consciousness and food market conditions. The results are as follows. 1. General life style and food life style, considered as family life style, were classified into 7 types and 9 types respectively as family life style by factor analysis. 2. The rationality of using and disposing stage on food life has increased, the rationality of the planning stage on food life has decreased since the IMF age began. But the rationality of overall food consumption has hardly changed. 3. The amount of purchasing was decreased, discount store was favorite place to buy food, and safety and freshness were major determinants in purchasing for most of food items. But this was different with food items. The various information sources were used impartially to buy food, cash was used mainly, and the degree of using the discount ticket/coupon was a little low. 4. Income level is an influential factor on the rationality of the planning and purchasing stage on food life, while environment-oriented food life style has influenced on the rationality of using and disposing stage. The purchasing amount of grain products, meats, milk products, bread and snacks, drinks, alcoholic drinks, water and convenience goods has influenced by demographic variables, eating out had been influenced by general life styles, and fruits, healthy foods, processed foodstuffs, favorite foods, vegetables seaweeds, import foods and seafood had been mainly influenced by food life style since IMF age began.

This study investigated the food life of 271 Korean American hoursewives residing in the New York and New Jersey metropolitan area. The objectives of this survey were to describe the food life of Koreans and to identify any demographic factors related to the food life. Most of the respondents(80.4%) considered dinner as the most important meal of the day and 97.4% preferred Korean foods for their dinner. More than half percents (54%) preferred to go out to eat at Korean restaurants. While 14.4% of the respondents reported always buying Kimchee, 47.2% of the subjects reported making their own Kimchee regularly. Although several studies showed that the food life are likely to occur spontaneously and to change constantly, most of the Korean Americans in this study appeared conservative in their food life. This study is expected to provide a baseline for a culturally specific nutrition program that would recommend immigrants to practice positive food life and nutrition behaviors. A more study about the effects of immigration on dietary patterns and diseases as well as other nutritional status would be needed.

시간-온도이력 지시계(TTI)는 시간-온도 이력에 따라 색이 변하는 작은 라벨로서 온도 의존성이 매우 중요한 성능 요소이다. TTI 색변화와 식품의 Arrhenius 활성화 에너지의 차이(${\Delta}Ea$)에 따른 shelf life 예측 오차를 수리적으로 분석하였다. 수리적 분석을 위하여 TTI의 kinetics는 0차반응, 식품은 1차반응에 해당하며 모두 Arrhenius 온도의존성을 따르는 것으로 가정하였다. TTI의 Ea가 식품보다 크거나 작은 경우 그리고 그 차이의 크기에 의한 효과를 분석하였다. 식품의 Ea가 TTI보다 작은 경우 온도변화에 따른 shelf life를 연산한 결과, TTI의 shelf life(색 변화의 종료 시점)가 식품의 shelf life(부패 시점)에 먼저 도달하였고, 식품이 TTI보다 큰 경우에는 식품이 shelf life에 먼저 도달하는 반대의 결과를 나타내었다. 또한 ${\Delta}Ea$의 크기가 클수록 shelf life의 차이도 크게 증가하였다. 결론적으로 TTI의 Ea가 식품보다 크거나 그 차이가 작을수록 TTI에 의하여 식품의 부패 시점이 안전하거나(shelf $life_{Food}$ > shelf $life_{TTI}$) 정확하게(shelf $life_{Food}{\fallingdotseq}$ shelf $life_{TTI}$) 예측됨을 알 수 있었다.
