A 371 agricultural households from 26 different communities in South Korea was subjected on a study of food taboos in January of 1966. To the pregnant women, those to whom a high protein diet is particurally important, as many as 14 different kinds of foods, mostly portein rich foods, were avoided to eat. It is believed that if duck is eaten while pregnant her baby may walk like a duck in later life. Some mother have a strong aversion to the rabbit meat that her unborn baby must be a harelip. It is feared to eat chicken, shark or carp by the pregnant mother for her baby may get a gooseflesh appearance, or fish scale-like skin in later life. It is thought that if mother eats soup made of meat borns, especially chicken bones, a disfigured baby may be born. Some area informed that if mother eats crab meat her future baby will always bubble. To the child-bearing mothers 13 different kinds of foods were avoided to eat. Some believe that if raddish kimchi, soybean curd, squash are eaten while dilivery that mother may get dental decay or to lose all her teeth. Other think that highly spiced raddish kimchi cause delivery difficult. To the lactating mothers 7 different items of foods were not recommended to eat. It is a common belief that eating green vegetables, especially fresh lettuce, are restricted that her baby may stool greenish. It is said that eating ginsen-chicken soup, or ginsen tea during lactating reduces breast milk secretion. To the weaning babies 7 different kinds of foods were prohibited to fee. Eggs are not eaten because mothers think her babies will start to talk very late. Eight different items of foods in cases of gastro-intestinal diseases, 5 items for liver disease, 7 items for high blood pressure as well as for paralysis were respectively restricted. It is said that meats including pork, beef, and chicken are neither desirable for the patients of high blood pressure nor those of paralysis. To the measles children 10 varieties of foods were restricted. Especially soybean products and meats were not encouraged to use for avoiding asecond attack of measles. For the common cold 8 different kinds of foods were aversed and men think that eating of soup of undria delays a recovery. For the tuberculosis 4 kinds of foods were prohibited to eat. It is said that wine, red pepper and ginsen will stimulate lung bleeding. Many mothers had a strong aversion to fermented shrimp and fish in case of style. and 5 different items of foods were restricted. In case of menstration not so many foods were restricted as other cases, but meat soup is not eaten in this condition in some areas. Majority of food taboos in Korean villages are neither based on tribal nor religious factors. But no one knows how, since what ages, from where, these food taboos have been transmitted and spread over the country. This survey found a great variety of food taboos, aversions, traditional beliefs and prohibitions latent unknown reseasons, or non-scientific conceptions, or completely different ideas from the modern medical aspect, or somewhat fallacious and superstitious beliefs. For the vascular disease contrasting approach were found between modern the oritical therapy and popular remedy among the rural populations who largely depend on the eastern medication. Further scientific study on either side should be done to lead the patient proper way. Many restricted foods such as rabbit, duck, chicken and fish are best resources of protein rich foods which are available in the village. Emphasis should be laid upon breaking down fallacious and supersititious food taboos through the extended nutrition education activities in order to improve food habit and good eating pattern for healthier and stronger generations of Korea.

The purpose of the study is to assess and evaluate methods employed in nutrition surveys and to give an information on methodological considerations for future studies in Korea. Three hundred thirty six papers of nutritional surveys published from 1960 to 1990 were classified into 9 groups according to the survey subject and analyzed for methods used in survey. The frequency of publications according to the survey subject was as the following order : 'in-fants and preschool children' 'school age children' 'adolescence' 'college students' 'preg-nant and lactating women' 'housewives' 'the elderly' 'workers' and 'patients' Eighty five percents of papers applied methods of dietary assessment. of which weighing method recall method an record method were extensively used in the order. Questionnairs included items related to nutrition such as food habit nutrition knowledge etc. Anthropometric techniques were employed in 53% of papers and in general growth measurement were undertaken for children and body composition was emphasized for adults. biochemical assessment was limited to 32% of papers and assessment of anemia was the major test. Clinical studies were applied to 26% of the studies. of which only 5% employed examination of clinical signs of malnutrition Recently self-reported health status assessed using questionnaires has been adopted frequently. Further researches are required for evaluation of the methods employed in nutrition surveys in order to develop the standard model for nutrtion survey so that obtained data can become more reliable and utilized efficiently.

Concentrations of major minerals(Ca, p, Na, K, Mg) and trace elements (Fe, Zn) were measured in human milk samples collected from 19 selected, healthy lactating women at 2~5 days, and at 4, 8 and 12 weeks postpartum. Decreases in the contents of m) or minerals and trace elements were found with the increase of time postpartum. Mean Ca contents of 2~5 days, 4 week, 8 week and 12 week in human milk were 243.02$\pm$50.90ug/ml, 295.0$\pm$65.70ug/ml, 295.0$\pm$41.50ug/ml, 349.90$\pm$83.50ug/ml, respectively And mean P contents of 2~5 days, 4 week, 8 week and 12 week in human milk were 134.70$\pm$49.4ug/ml, 134.90$\pm$19.70ug/ml, 117.60$\pm$18.90ug/ml, 130.60$\pm$28.20ug/ml, respectively. Ca/P of them were 1.81, 2.19, 2.20, 2.68, respectively. Mean Mg contents of them were 22.30$\pm$5.60ug/ml, 25.70$\pm$3.70ug/ml, 25.10$\pm$3.60ug/ml, 32.10$\pm$4.50ug/ml, respectively. And mean Na contents of them were 171.20$\pm$90.50ug/ml, 158.70$\pm$47.00ug/ml, 104.50$\pm$24.70ug/ml, 115.90$\pm$12.50ug/ml, respectively. Mean K contents of them were 506.10$\pm$156.10ug/ml, 520.90$\pm$55.00ug/ml, 370.10$\pm$29.00ug/ml, 468.40$\pm$75.70ug/ml, respectively. Na/K of them were 0.34, 0.30, 0.28, 0.25, respectively. Mean Fe contents of them were 2.80$\pm$1.80ug/ml, 2.70$\pm$0.40ug/ml, 2.60$\pm$0.40ug/ml, 2.10$\pm$0.10ug/ml, respectively. And mean Zn contents of them were 3.70$\pm$1.60ug/ml, 2.78$\pm$9.70ug/ml, 2.70$\pm$0.70ug/ml, 2.30$\pm$0.20ug/ml, respectively, These determinations will provide the basic information on the variability of major minerals and trace elements as lactation proceeds and on the composition of components between term and preterm milk.

The levels of indicator PCBs were determined in 132 human milk samples (Colostrum, 30th days after delivery, 60th days after delivery) collected in 2006 according to World Health Organization's (WHO) protocol. In addition, concentrations of indicator polychlorinated biphenyls (PCBs) were measured by the isotope dilution method with high resolution gas chromatograph/high resolution mass detector (HRGC/HRMS), which gave accurate and precise data for estimations of international trend and comparisons. Average daily intakes (ADIs) of all analytes were calculated. The median level of total indicator PCBs was 14 ng/g lipid, which is significantly lower than the level found in individuals from other countries. PCB congeners 138, 153 and 180 accounted for about 65% of the sum of the indicator congeners analyzed. The concentration of the most abundant PCB 153 is positively correlated with the concentration of the sum indicator PCBs (p<0.001). In this study, concentrations of total indicator PCBs significantly decreased with increasing number of children for a mother, indicating that parity and breast-feeding period an important role in the accumulation and elimination of these compounds in lactating women. The ADI for the median of total indicator PCBs for an infant was evaluated at $0.077{\mu}g/kg{\cdot}bw/day$ from birth to 6 months of age. The present study shows that concentrations of PCB 118 primipara breast milk have decreased 25~35 since 1998, and that this trend is continuing.

Concentrations of iron. zinc, and copper were measured in human milk samples collected longitudinally from 21 highly selected. healthy lactating women. And the daily milk and trace elements intakes of 14 exclusively breastfed infants were determined by the test-wei-ghing procedure and the direct analysis of milk samples at 6 or 7weeks postpartum. Significant decreases in iron. zinc and copper were found with time postpartum. Iron contents decreased from 0.33$\mu\textrm{g}$/$m\ell$ at 2-5 days to o.21$\mu\textrm{g}$/$m\ell$ at 12weeks. Zinc concentrations also declined from 4.15$\mu\textrm{g}$/$m\ell$ in colostrum to 2.33$\mu\textrm{g}$/$m\ell$ in matured milk at 12 weeks. Mean copper levels of colostum, transitional. and matured milk were 0.21$\mu\textrm{g}$/$m\ell$, 0.34$\mu\textrm{g}$/$m\ell$, and 0.26$\mu\textrm{g}$/$m\ell$ respectively. Data indicated that the amount of milk ingested ranged from 432g/day to 1266g/day and the mean intake was 768g/day. Daily mean intakes for iron, zinc, and copper were 0.19mg, 2.10mg, and 0.15mq respectively.

Concentrations of 5 major minerals(Na, K, Ca, P, Mg) and 3 trace elements(Mn, Mo, Ni) were measured in human milk samples collected from 21 highly selected healty lactating women at 2-5 days and at 1, 2, 4, 6 and 12 weeks postpartum. Significant decrease in contents of the major minerals and trace elements were found with time postpartum. Sodium contents decreased from 293.01ug/N at 2-5 days to 194.27ug/N at 12 weeks. Potassium contents also decreased from 436.18ug/N in colostrum to 358.51ug/N in matured milk at 12 weeks. The Ca/P ratios of colostrum transitional and matured milk were 3.39, 281 and 2.45 respecti-vely. Mean manganese levels of colostrum and transitional were 0.024ug/N and those of matured milk were 0.014ug/N. Molybdenum concentrations in the breast-milk collected at 1, 2, 4 weeks were higher than those in the milk samples at 2-5 days and 12 weeks Nickel content of colostrum was 0.062ug/N and those of trnsitional matured milk were 0.22ug/N and 0.017ug/N, These determinations will provide the basic information on the variability of minerals and trace elements as lactation proceed and the comparison of the components between term and preterm milk.
