This study was performed to compare dietary behaviors based on residence types of female college students. Self reports on dietary behavior and one-day dietary records were obtained from 227 female college students using anonymous questionnaires. The mean age of the subjects was $20.4{\pm}1.43$, and the height and weight were $162.5{\pm}4.8cm$ and $52.3{\pm}7.9kg$, respectively, The dietary behavior of female college students was inadequate, showing indifference to dietary balance, irregularity of meals, skipping breakfast, and high experience of drinking. One-day dietary records were obtained from 24k recall methods also showed a high number registering skipped meal status ($55.3\%$) and less diverse food intake (DVS, 12.5; DDS, 3.93). The students in self boarding residence were especially more likely not to eat properly and their dietary behaviors were found to be significantly poor. In the case of home residence, food intake frequency scores for milk and dairy products, fruits, and fishes were significantly higher, however the students in self boarding residences showed high food intake frequency scores in salted food, retort food, canned food, and especially instant ramyun. Therefore, more attention needs to be given to them to recognize the problems in their own dietary behaviors and more practical nutritional supports, like developing a menu for breakfast in college cafeterias, would be helpful to improve their dietary choices.

Nutrition fortification of processed foods with microelements is a popular practice in many countries to improve nutritional status of target population. In this study the current food fortification in Korea was evaluated and the regulations and guidelines for food fortification in other countries were presented. Most commonly added nutrients were calcium, vit.C, fiber, vit.Bs and iron. The level of fortified nutrients and the vehicle foods were variable. vit.C and fiber appeared to be overfortified in some foods and the necessity of fortification of these nutrients needs to be examined since the intakes of these elements appears to meet the RDA. Most of other nutrients such as vit.A, vit. $B_1$, vit. $B_2$, and iron were added at the level of 10~25% RDA per serving size. The vehicle foods for fortification were snacks, milk, ramyun, breakfast cereal, juices, candies and ready-to-eat retort pouch foods but not rice which is a staple food in Korea. The guideline and regulation for food fortification is required to ensure safe and proper supplementation of needed nutrients in processed foods.

Current status of nutrient fortification in processed food in Korea were presented by analyzing the information shown on food labels. The obtained information was assessed by the regulations on food fortification in both Korea and other countries including Codex. The most current regulations were gathered from internet. The results are summarized as follows. 1. Major nutrients fortified were calcium, Vit C, Vit B complex, iron and fiber. The forfified foods were not limitted to certain food group with more frequent fortification in snackfoods, cereal, ramyun, retort pouch foods, milk, and youguart. The descriptive terms of nutrition label for the fortification were various including high, supplemented, added, source, fortified, and abundance though the difference among these terms were not distinct. 2. Current regulation on nutrition label requires to give the content of the fortified nutrient and % RDA. However not all of food items carry above information. Also some ingredients such as chitosan, DHA, taurine, $\omega$-3 fatty acid, chondrichin, bifidus were supplemented mainly to the snack foods which FDA(USA) does not allow to be fortified. 3. The nutrient most frequently fortified was calcium and general practice of fortification appears to follow the regulation in Korea. Presently the regulation itself is not well described, this nutient fortification can cause toxic effect. Since calcium was supplemented to wide range of food group consumers who are not conscious of the safe upper limit may intake the fortified food up to the level of 2g/day. 4. For the effective fortification in Korea, the regulation on fortification should be reformed in accordance with the international guideline Codex and the regulations in other countries especially in America and Japan.

In order to investigate food purchase frequency of elementary school children and its related ecological factors, 431 4th, 5th and 6th grade elementary school children and their mothers, living in Seoul and Daejon, small city and rural area of Chungnam Province, were participated in this study. The subjects and their parents were surveyed by a self-recording questionnaire about food purchase frequency and some ecological factors. Average height and weight of the subjects by gender and grade were similar to or a little bit more than the 1998 Korean Growth Standard. According to relative body weight, 30.6% and 10.8% of the subjects belonged to under-weight and obesity categories, respectively. Of the subjects, 46.9% used PC telecommunication or internet, 53.8% of them used it for less than an hour per day, and 46.4% watched TV for 2 to 4 hours a day. About 42% of the subjects spent 500 Won or less daily to buy snacks. A half of the subjects took snacks once a day because of hunger. Mothers' nutrition knowledge score was averagely 8.16 out of 13 full score and the average attitude score was 43.22 out of 50 full score. Foods purchased more than once a week were milk and yoghurt, cookies, ice-cream, ramyun, and gum in order. Family income, parents' education level, mothers' nutrition knowledge and food attitude score, students' snacking frequency and TV watching time showed significant correlations with purchase frequencies of some individual food items. In conclusion, the elementary school children considered taste most important rather than nutrition in buying snacks and most frequently bought carbohydrate foods and concentrated sugars except milk. Ecological factors such as mothers' nutritional knowledge and food attitude, TV watching time and snacking frequency had influenced the children's food purchase frequency. Accordingly, it is necessary to educate both children and their mothers about good food purchase and the importance of snacking.
