This study was conducted to investigate the effect of intramuscular fat scores on pork quality assurance. Pork loins were collected from animals (110-120 kg body weight) slaughtered in a commercial slaughterhouse, assigned an IMF score (1-3) from and stored for 24 hrs at $-3^{\circ}C$. Samples were analyzed for chemical composition, pH, cooking and drip loss, shear force, meat color, and texture characteristics. The moisture, crude protein and crude ash content were not significantly different among the various IMF score groups. The crude fat content of the IMF score 3 group was significantly higher than the IMF score 1 and 2 groups (p<0.05). The pH values of the IMF score 2 and 3 groups was significantly higher than the IMF score 1 group (p<0.05). There was a no significant difference in shear force value and cooking loss among the IMF score groups. The purge loss content of the IMF 3 group was significantly lower than that of the IMF score 1 group (p<0.05). The increase in IMF score resulted in lower hardness, gumminess, and brittleness values. The hardness and gumminess of the IMF score 3 group were significantly lower than those of the IMF 1 score group. The adhesiveness, cohesiveness, and springiness were not significantly different among the IMF score groups. With regard to meat color traits, lightness ($CIE\;L^*$) was not significantly different among the IMF score groups. The $a^*\;and\;b^*$ values correlated positively with the IMF score. In general, the results of this study show that the CIE color values and drip loss had a positive correlation, while only redness was positively correlated with shear force and hardness. pH was negatively correlated with CIE color values and drip loss, while positively correlated with moisture content.

The objective of this study is to determine the effectiveness of 16-month milk consumption as a part of the health promotion community program for women in Asan. Subjects included 313 women belonging to the milk group (mean age = 69.1, range $47{\sim}89 y$) and 66 women to the control (mean age=43.6, range $20{\sim}69 y$) group. For those in the milk group, one cup (200 ml) of partially lactose-digested low-fat milk was provided everyday for 16 months. Each subject was interviewed to assess calcium intake by a 24-h recall after fasting blood was obtained for analyzing bone turnover markers, and calcaneus broadband ultrasound attenuation (BUA) was measured by quantitative ultrasound (QUS) on the left heel before and after the milk supplementation. After 16 months, the calcium intake levels changed from 55% of recommended dietary allowance (RDA) to 85% RDA in the milk group and from 73% RDA to 84% RDA in the control group. BUA were reduced from $67.9{\pm}8.1$ to $64.7{\pm}17.5$ dB/MHz for milk and from $90.4{\pm}13.0$ to $87.2{\pm}15.2$ dB/MHz for control groups. Paired t-test showed the changes of BUA for both groups (-3.24 and -3.15 dB/MHz for milk and control groups, respectively) were significant, but the two groups did not show any differences in absolute changes. When post-BUA was analyzed after age, initial BUA and menopausal status were controlled as covariates in ANCOVA model, the milk group showed significantly (p < 0.05) smaller changes than the control group (-3.50 vs -6.71 dB/MHz, respectively). According to a multiple regression analysis, milk consumption and initial BUA showed significant interaction meaning that those with lower initial BUA showed higher milk effects. We conclude that one-cup a day milk consumption for 16 month can prevent further bone loss and significantly improve calcium intake.

This study was conducted to investigate Korean youths' use of fastfood and family restaurants in different regions, especially among cities and rural towns. Total 1,600 questionnaire surveys were distributed to Junior high and Senior high school students and 1,487 were used for the analysis. In order to consider regional differences as well as overall characteristics of youths' fastfood and family restaurant visiting behaviors, the subjects were evenly sampled from north Seoul, south Seoul, big cities, middle/small cities and small towns. As for the frequency of visiting fastfood restaurants, 58.3% of the respondents answered 'once to five times' a week. South Seoul area showed the highest frequency. 'Easiness' was the main reason of eating fastfood, which was up to 57.8% of the overall respondents while 42.8% of the small town youth ate fastfood because of the 'good taste.' As for the concepts on fastfood, 42.7% understood it as 'easy to eat' while 33.6% responded as 'easy to get fat.' For the question of getting channel of fastfood information, 44.8% answered 'TV' and 28.3% responded 'from friends.' Coupons were found to affect fastfood restaurant visits, highest in south Seoul, and lowest in small cities. For the question of the relationship of Koreanized menus and fastfood restaurant visits, small towns showed the highest frequency, while South/North Seoul had the lowest frequency. For the percentage of visiting family restaurants, respondents answered in the order of South Seoul(59.7%), North Seoul(44.5%), Big cities(39.5%), small cities(19.4%), and small towns(13.1%). Most of youth visited family restaurants because of the taste, while youths of middle/small cities visited due to the atmosphere. The effect of coupons on visiting family restaurants were found to be lower than the one of fastfood restaurants. Korean youths were found to visit fastfood restaurants very frequently in all regions and the tendency of visiting family restaurants is also increasing. At this point, balanced menus and education for healthy eating habits are urgently needed for the youth.
