        The purpose of the present study is to collect information in terms of the frequency and amounts in frequently consumed dishes. We conducted the secondary analysis from '93 Korean National Survey. Mainly informations about 2-day food records were used to investigate dish intakes and to compare different food patterns by area. Amounts of total daily intakes of dishes per capita are 1,741.46g in nationwide, 1,722.03g in large city, 1,712.46g in small city, 1,808.73g in rural. The dish consumed in largest quantities per capita per day is the rice which amounts is 481.67g, 27.66% of total intake. Fruits and cabbage were consumed in large quantities too. Kimchi made of cabbage have the highest number of frequencies. Number of frequencies in rice, fruits, and milk showed high, too. Dish groups are classified by the cooking method. Some dishes in several dish groups have small number of frequencies and small amount of quantities. Some dishes in the top list are not included in the 30 dishes list. There should be some studies about validity and reliability of the dish list, using individual dietary assessment methods.

        The purpose of the present study is to collect information in terms of the frequency and amounts in frequently consumed foods. We conducted the secondary analysis from '93 Korean National Nutrition Survey. Mainly informations about 2-day food records were used to investigate food intakes and to compare different food patterns by area. Amounts and frequencies of food intakes are on the list by the order of contributing amounts and frequencies. Amounts of total daily intake of food per capita are 1,054g in nationwide, 1,076g in large city, 1,049g in small city, 1,017g in rural. The major foods consumed in large quantities were rice, kimchi, milk, in nationwide, large city, and small city and rice, kimchi, Korean radish in rural. The intake frequency of kimchi, rice, and basic seasonings as garlic, green onion, salts, soy sauce et al, were higher than other foods in all area. However, there are need for further researches to investigate individual dietary intake and seasonal variation of intakes. Also, food consumption patterns for different groups considering age, sex, area should be studied.

        The dietary intake of nutritional elements by Koreans as determined by the Ministry of Health and Welfare's National Nutrition Survey have been reported for 1969~1993. But these data were based on not dish but food. Therefore, the purpose of this study was to compare dish sources of energy and macronutrients (carbohydrate, fat, protein) in the diets of three area (large city, small city and rural). Dish sources were evaluated from two-day record obtained in the secondary analysis of the 1993 Korean National Nutrition Survey. The result, large city and small city had higher fat and protein intake than did rural. Otherwise, carbohydrate intake among rural was higher than those among large and small city (p〈0.05). The primary dish source of energy and macronutrients was cooked rice for all area. The percentage of cooked rice in daily carbohydrate intake was 52.64% for nationwide, 48.40% for large city, 50.52% for small city, 61.79% for rural. The cumulative percent of top 10 dish sources to carbohydrate for large city, small city, rural were 78.02%, 81.16%, 85.69%, respectively. These was higher than cumulative percent of other macronutrients. The milk as good protein source ranked 3 for large city, 6 for small city, 22 for rural. The major dish sources to fat were cooked rice and pork that prepared by various cooking way. These results show that the major dish sources of energy and macronutrients were cooked rice based of Korea traditional consumption pattern. The most of nutrient intake consumed some dishes for all area. The dish consumption pattern was generally similar between large and small city. But rural was different from other area. Threfore, nutrition educations and interventions should be targeted to each area and should be attended with studies that comparision of dish sources to nutritional elements by specific age-sex groups.

        Heavy metal ions in water were removed using algal biomass as adsorbents. Absorbents were dried for 3 days, ground them by 40∼60 mesh and then were swelled in a buffer solution for 1hr. After being packed in the column, commercially available standard solution of Cd(Ⅱ) and Pb(Ⅱ) ions were diluted to get the suitable concentration and then it was eluted with the rate of 1 ㎖/min. Heavy metals on the adsorbents were recovered with nitric acid. More amounts of Cd(Ⅱ) or Pb(Ⅱ) ions in green algae, Ulva pertusa, than in brown algae, Sargassum hornerl, were adsorbed. Pb(Ⅱ) ion was adsorbed more than Cd(Ⅱ) ion in both algae. The pH effect of adsorbed amounts of Cd(Ⅱ), Pb(Ⅱ) ions on the biomass was shown the following order ; pH 10.5 > 8.5 > 7.0 > 5.5 > 3.5. Recovery ratio of metal ions from algae is shown higher in acidic or neural conditions than It in alkalis ones. Pb(Ⅱ) ion is recovered relatively more than Cd(Ⅱ) ion in our system.
