Purpose: This study was conducted to investigate food supply and consumption trends in South Korea over the past 30 years (1980 to 2010). Methods: We used time series data on Food Balance Sheets of Korea and the National Health and Nutrition Survey from Korea Statistics. Regression analysis was performed for trends of food supply and demand, and t-test for the gender difference in nutrient intake. Results: The annual supply of cereals, rice and starch roots per person has decreased, while that of meat, fish and shellfish, eggs, milk, and fats and oils has increased (p < 0.05), respectively. These changes effect on nutrient intake: rice consumption has declined to one-third of total energy intake, however, the energy intake from lipid sources has increased up to 20% in the 2000s.The nutrient intake levels are mostly sufficient to meet the recommended intake, but calcium intake is below the recommended level and sodium is three times above the recommended level. These problems are found in both genders, and males take in more calories and sodium than females (p < 0.05). Conclusion: These changes in food consumption and supply resulted in lowering both quantities based food self-sufficiency rate and self-sufficiency of nutrition supply. It is therefore suggested that the supply of agricultural products should be stable and quality competitiveness in supply should be improved. Also, measures and strategies in promoting rice consumption are required, such as promoting healthy diet via nutrition education and disseminating healthy traditional Korean food.

In this paper, we establish several interesting relationships involving the Fourier-Feynman transform, the convolution product, and the first variation for functionals F on Wiener space of the form F(x)=f(〈α1,x〉,…,〈αn,x〉),                                                      (*) where 〈αj,x〉 denotes the Paley-Wiener-Zygmund stochastic integral ∫0Tαj(t)dx(t)
