  • The purpose of this research was to find effects of high fat diet and endurance exercise on mitochondria biosynthesis and insulin resistance in male Wister rat. Th rats were randomly separated into 4 groups: A, Isocaloric high fat diet group (50% of calories from fat), B. Chow group, C. Isocaloric high fat diet with endurance exercise (treadmill running, slop 8%, 23 m/min, 120 min/day, 5 days per week), D. Chow group with endurance exercise. Both Isocaloric high fat diet group and chow group were given an equal caloric composition with 3.2kcal/g. equal amount of food were checked every day and given to both groups. 4 weeks of high fat diet did not show any change in body weight and amount of body fat. Further the level of glucose and insulin in blood, and insulin-stimuilated glucose transport rate in epitrochlearis muscle was not affected by Isocaloric high fat diet. However, the endurance exercise showed statistically significant change in the level of insulin in blood. Although either Isocaloric high fat diet or endurance exercise alone did not change on mitochondria biogenesis marker, Isocaloric high fat diet with endurance exercise could induce the increased level of marker (p<0.05). Also, plasma free fatty acids were increased in this group. From this investigation, Isocaloric high fat diet with moderate-intensity endurance exercise is effective way to induce mitochondrial biogenesis.

  • This study was conducted to examine the consumption realities of processed food and the perception of food labeling with targets of university students attending schools in Daegu and Gyeongbuk areas. The reason for buying processed food was because it is easy to cook. As for the number of using processed food, it was answered that everyday dairy products, noodles, breads and snacks for 3~4 times a month, and meat processed foods, canned foods, sauces and frozen foods for 2~3 times a month. With regard to selecting processed products, both male and female students answered with taste and price first, barely considering the safety and nutritional elements. It turned out that they check the price, expiration date and country of origin in order upon buying processed foods. Most of them recognized food labeling, but answered that they checked it sometimes in order to check the 'expiration date' and the 'calories'. They were aware of the food nutritional contents indication. It was turned out that male students check it for nutrients and female students for weight control. The effect of the processed food indication was that it is easy to choose the necessary foods for health and as well as for comparing the food with other products. The satisfaction of the food labeling system was mediocre. The results indicated that the food indication system needs to be educated or promoted.

  • This study was examined the quality characteristics of dough liquid according to the additional ratio of Doraji in seaweed snack manufacturing. Firstly, the results of Doraji type (dry & powder) were as follows: Carbohydrates 77.57~79.29, crude protein 9.10-9.25, crude fat 0.96~1.33 and calories 355~366 kcal, pH 5.42~5.45, sugar $3.53{\sim}3.96^{\circ}brix$, color 33.82~44.25 (L), 2.27~3.52 (B) and total free amino acids 2,200~2,699 mg/100 g. Total polyphenol contents had dry extracts 1,931.18 mg% and powder extract 1,382.43 mg%, DPPH and ABTs radical scavenging activities tended to increase with higher treatment concentration. Next, the results showed that dough liquid for seaweed snack manufacture which was added Doraji were as follows: Color became deep poppy red with increased addition of Doraji. The texture of adhesiveness, cohesiveness, chewiness, and brittleness tended to decrease with addition of Doraji. The springness showed the opposite tendency. Accordingly, these results suggest that 20% of dry Doraji extract is a proper proportion so that it can be added to the rice dough liquid to produce form Doraji (dry and powder) containing seaweed snacks.

  • This study estimates the random utility function of fluid milk using 1,165 survey responses in Laos. It finds that both products' attributes and individual characteristics affect consumers' preference for the milk and the hypothetical brand of Laos-Korea has a potential compared to four real dairy products. Results also show that calories have a positive relationship with consumer's preference while the price and fat content have a negative one. The decision for choosing each brand is significantly affected by individual characteristics such as gender, age, whether or not respondents live with their children, the level of education, income, the frequency of purchasing milk per week, and the region where they live. The preference for five brands appears in the order of Foremost, Nabong, Thai-Danish, Meiji, and Lao-Korea, and probabilities of purchasing each brand at the mean level are 30.9%, 17.48%, 21.48%, 15.0% and 10.39%, respectively. Nabong that was Lao national milk brand still has a significant market power even though it was closed in 2008. The policies to promote milk industry by implementing its national milk brand again would be more effective if it focuses on the young generation, female consumers, families with children, quality of dairy products, and Vientiane capital areas.

  • The purpose of this study was to analyze a cohort, age, and time effects on sodium and sodium-calorie intake using the 2007~2017 Korea National Health and Nutrition Examination Survey (KNHANES). For analysis, we have constructed cohort panel data that combine KNHANES data in a time series. The age effect gradually increased from age 45~49 and then decreased afterwards. The time effect showed an increase in average sodium intake until 2010 followed by a subsequent decrease. The cohort effect showed that the sodium intake was the highest for the War of Liberation 1946~1953, and that the younger the latter, the lower the sodium intake. According to a cohort analysis, the younger the generation, the lower the sodium intake compared to the calorie intake, according to the baby boomers. Based on the results of this study, efforts should be made to educate and promote the dieting and providing low-salt meals to reduce sodium intake by generation. An analysis of the health hazards including sodium by generation and age is thought to enable the establishment relevant policies.

  • The changes of life-style by improving the standard of living produce the development of food service industry. But, the consequence is that food waste also increase. I think that the problems about the food waste become more critical. There are some reports about counting the amount of remaining foods until now. But, I can not find reports about the calory analysis of the remaining foods. So, I analysis the amounts and calories of the food and remaining food served at the restaurants for the purpose of groping how to reduce the remaining food and conclude as follows. First, the average amount of the food giving to one person is 1007gm(from 300gm to 1367gm), and the average amount of the remaining food is 126gm(from 29gm to 172gm). Second, the average calory of the food giving to one person is 795.5kcal(from 464kcal to 1225kcal), and the average calory of the remaining food is 140.8kcal(from 29kcal to 289kcal). So, we gain 130kcal more than recommending calory to woman. Therefore, we need to studies of developing menu, controlling the amount of supplied food, and improving how to supply. Also we need to study about the using of food bank and publish and use about recycling of food waste.
