This study was carried out to changes in chemical and microbiological properties of spring waters in Tongyeoung area. In this paper, ninety spring water samples were collected from 9 station for 11 month to evaluated chemical and bacteriological water quality. Range and mean values of constituents of the samples are as followed; water temperature 5.2-25.8℃, 16.3℃, pH 6.0-7.2, 6.7, total residue 33.6-210 mg/1, 90.6 mg/1, turbidity 0.35-5.48, 1.45NTU, KMnO4 consumed 0.51-4.21 mg/1, 1.39 mgll, chloride ion 6.23-42.5, 16.7 mg/1, phosphate-phosphorus ND-0.04, 0.02 mg/1, nitrite-nitrogen ND-0.02, 0.01 mg/l, nitrate-nitrogen ND-3.56, 1.42 mg/1, ammonia-nitrogen ND-0.20, 0.14 mg/1, dissolved total nitrogen ND-3.78, 1.57 mgll, iron 0.04-0.28, 0.13ppm, zinc 0.03-0.66, 0.20ppm, mangan ND-0.01, allumium 0.14-0.58, 0.39ppm, copper ND-0.01, 0.01, lead ND-0.01, 0.0lppm, Arsenic ND-0.01, 0.0lppm, mercury ND-0.02, chrome not detected, cadmium not detetced respectively. The viable cell counts of the spring waters ranged 5.0760/m1(means 130/m1). Range and mean value of total coliform and fecal coliform MPN's of the spring waters were 0-2,400MPN/100 ml, 73MPN/100 ml and 0-540MPN/ 100 ml, 21MPN/100 ml. Spring water quality was usually poor with viable cell counts exceeding 130 CFU/liter and the coliform counts in spring waters of 73 MPN/liter. Composition of coliform by IMViC reaction was 33.3% E. coli, 15.6% Citrobacter freundii, 35.6% Klebsiella aerogenes and others.

This study was conducted to assess dietary intake and quality obtained by 24-hour recall method between Korean-Chinese in Yanbian, China(Korean-Chinese) and Koreans in Kuri, Korea(Koreans). The subjects consisted of 730 Korean-Chinese and 696 Koreans. Mean daily energy intake of Korean-Chinese was 1,788kcal and that of Korean was 1,844kcal. Proportions of energy intake from carbohydrate, fat, and protein were 62.6: 16.9: 14.2 for Korean-Chinese and 65.4: 16.3: 14.4 for Koreans. Nutrient intake levels of Koreans were higher than those of Korean-chinese in most nutrients. Calcium and vitamin B2 intakes as percent of Korean RDA were less than 60% in Korean-Chinese. Koreans consumed calcium and vitamin A in the level less than 80% of Korean RDA. Iron intake level of Korean females was less than 75% of Korean RDA. Korean-Chinese consumed 90.4% of food from plant origin, and Koreans consumed 82.5% of food from plant origin. Mean dietary diversity score(DDS) of Korean-Chinese, 3.00±0.39, was significantly lower than that of Koreans, 3.73±0.76(p<0.05). Mean dietary variety score(DVS) of Korean-Chinese, 13.6, was significantly lower than that of Koreans, 20.1(p〈0.001). According to these results, some adults in the both Korean-Chinese and Koreans did not consume enough nutrients, especially calcium and vitamin B2 intake for Korean-Chinese and calcium and vitamin A intake for Koreans. Dietary qualities of Korean-Chinese subjects and Korean females were not adequate. In the future, further research to promote dietary quality of Koreans including Korean-Chinese must consider the results of this study.
