This study was performed to assess the nutritional status and hair mineral content of children with behavioral problems and compare the values with a gender, age-matched control group. The subjects were recruited from S elementary school children in Seoul, Korea. Students scored higher than 60 points were diagnosed with behavioral problems according to the Korean-Child Behavior Checklist. Nutritional assessment of the two groups (behavior problem group: male n=15, female n=24; $9.6{\pm}1.6$ years, control group: male n=16, female n=18; $9.5{\pm}1.9$ years) was performed using a nutritional survey and by measuring hair mineral contents. In the results, food frequency questionnaire analysis showed that the intakes of anchovy (P<0.05), soybean curb (P<0.01), radish (P<0.05), bean sprouts (P<0.05), spinach (P<0.05), carrot (P<0.05), pumpkin (P<0.05), lettuce (P<0.05), cabbage (P<0.01), apple (P<0.05), and milk (P<0.01) were higher in the control group than the behavior problem group, whereas intakes of ramyeon (P<0.05), cookies (P<0.05), and coke (P<0.01) were higher in the behavior problem group than the control group. Intakes of most nutrients such as plant-derived protein (P<0.05), fiber (P<0.05), plant-derived calcium (P<0.05), phosphorus (P<0.05), plant-derived iron (P<0.05), vitamin B2 (P<0.05), vitamin B6 (P<0.05), vitamin C (P<0.01), vitamin E (P<0.05), and folate (P<0.05) were significantly higher in the control group than the behavior problem group. Hair analysis showed that the levels of arsenic (P<0.05), mercury (P<0.001), uranium (P<0.05), iron (P<0.001), boron (P<0.01), and germanium (P<0.001) were lower, but the levels of phosphate (P<0.05), chromium (P<0.001), sodium (P<0.05), and sulfur (P<0.001) were higher in the behavior problem group than the control group. Conclusively, behavioral problems constitute a complicated condition in which nutritional factors may play major roles. However, it is still under investigation as to whether or not modification of dietary habits or nutritional supplementation can improve children's behavior, since symptoms require a broad understanding of the environmental and genetic interactions.

This study was to investigate physicochemical properties of Shinan seomcho growing in Jeollanamdo. The samples used were Shinan seomcho(Josaeng, Mansaeng varieties), Pohangcho(Josaeng, Mansaeng varieties), Namhaecho (Josaeng, Mansaeng varieties) and greenhouse spinach(Josaeng varieties). The results were as follows ; The thickness of spinach leaves were contained in order of Shinan seomcho > Pohangcho > Namhaecho > greenhouse spinach, and the hardness of those were contained in order of Pohangcho > Namhaecho > Shinan seomcho > greenhouse spinach. In Hunter's color value, L, a, b value in greenhouse spinach was lower than those of the others. Among the spinach varieties, Josaeng-jong(3.39~5.38 mg%) had the highest level of total dietary fiber contents than that of Mansaeng-jong(2.94~3.91 mg%). By regional groups, total dietary fiber were contained in order of Pohangcho > Namhaecho > Shinan seomcho > greenhouse spinach. The free sugar contents in the sample group, Shinan seomcho(4 varieties), Pohangcho(1 variety) and Namhaecho(2 varieties) were higher than those of other spinach varieties. The total sugar contents in the sample group, Shinan seomcho(3 varieties), Pohangcho(1 variety) and Namhaecho(2 varieties) were higher than those of other spinach varieties. Total flavonoid contents of Shinan seomcho(Josaeng-jong) and Namhaecho(Josaeng-jong) were lower than 130 mg%, but the other spinach had more than 130 mg% of total flavonoid contents. Germanium contents were detected in the following order ; Shinan seomcho(47.46 ${\mu}g$/kg) > Namhaecho(30.13 ${\mu}g$/kg) > Pohangcho(26.39 ${\mu}g$/kg) > greenhouse spinach(25.32 ${\mu}g$/kg).
