This study was carried out to compare the characteristics of the over weight elementary school students with those of desirable-weight children. Anthropometric parameters such as height, weight, BMI, body fat percentile, triceps skin fold thickness were measured. Dietary assessment and blood analysis were performed. The average ages of over weight children and desirable-weight children were 10.9$\pm$2.5 and 10.2$\pm$2.8 years, respectively. The means body fat percentile of over weight children and desirable-weight children were 27.5$\pm$3.7% and 20.2$\pm$3.8%. respectively. Plasma levels of TG, total cholesterol, LDL cholesterol, and HDL cholesterol of over weight children and desirable-weight children were 179.3$\pm$30.0, 104.9$\pm$26.6, 52.3$\pm$6.7 and 178.3$\pm$84.1 mg/dl, and those of desirable-weight children were 86.1$\pm$43.5, 183.7$\pm$16.5, 101.0$\pm$2.1 and 67.7$\pm$20.0 mg/dl, respectively. Plasma TG levels of over weight children were significantly higher than those of desirable weight children. On the other hand, plasma HDL-cholesterol levels of over weight children were significantly lower than those of desirable-weight children. Plasma levels of GOT and GPT were in normal range in both group however, GPT level of over weight children was higher than that of desirable weight children. Plasma levels of albumin, globulin, and BUN were all in normal range and no differences were found in both groups. Hematologic data did not show any difference between two groups except WBC, RBC and Hgb levels which were significantly higher in over weight group than those of desirable-weight children. Daily nutrients intake of over weight children and desirable-weight children were very similar and they were around the Korean RDA levels for each nutrients. However the intake of calcium of both groups were little over 50% of RDA. The consumption of dietary fiber was very low and the cholesterol intake was very high showing that the habitual meals of Korean school children were not well balanced.

Purpose: The purpose of this study was to compare physical self-concept, academic self-concept and depression among obese and over-weight and normal weight children. Methods: The 6th grade children in two elementary schools (n=287) completed self-report questionnaires measuring self-concept and depression. Results: The mean score of depression and self-concept in normal weight children were 9.76 and 92.59. In obese and over-weight children, depression and self-concept were 12.31 and 86.69 respectively. Subjects who were obese and over-weight showed significantly lower scores of physical self-concept (t=-4.621, p<.001) but not significantly low in academic self-concept (t=-1.065, p=.288) than normal weight children. Meanwhile, this study shows that subjects who were obese and over-weight were significantly higher level of depression than subjects in normal weight (t=2.480, p=.014). Conclusion: In conclusion, obese and over-weight children showed negative aspects in the developmental course. This study demonstrates that obese and over-weight children should be treated as a risk group who needs any professional help such as a school mental health program for normal development.

This study was conducted in order to investigate the effect of diet therapy on over weight and obese humans in Korea Subseng Research Institute from January 1, 1994 to August 31, 1997. The constitutions of subjects were classified mild negative, strong negative, mild positive and strong positive respectively by ecology and O-ring test. These results were obtained from the subjects who practiced at least 75% diet therapy recommended for over weight and obese human for 14~400days. The constitutions of over weight and obese human by Relative Body Weight (RBW$\geq$110%) were 89 mild negative humans, 62 strong negative humans, 56 mild positive humans and 30 strong positive humans. The constitutions of over weight and obese human by Body Mass Index(BMI$\geq$25) were 77 mild negative humans, 50 strong negative humans 46 mild positive humans and 23 strong positive humans. The negative subjects were higher than the positive subjects on over weight and obese humans. The diet therapy related to constitiution on over weight and obese humans showed RBW reduction of 6.73$\pm$0.53 on mild negative human, 7.78$\pm$1.69 on strong negative human, 6.94$\pm$0.76 on mild positive human, and 7.80$\pm$1.15 on strong positive human at p<0.001 by student paired t-test. The diet therapy related to constitution on over weight and obese humans showed BMI reduction of 1.47$\pm$0.12 on mild negative humans, 1.24$\pm$0.11 on strong negative humans, 1.59$\pm$0.17 on mild positive humans, and 1.66$\pm$0.30 on strong positive humans at p<0.001 by student paired t-test.

이 논문에서 Z$_4$상에서 정의된 Delsarte-Goethals 부호의 완전 무게 분포를 구하였다. 이 부호의 부호어를 3가지 경우로 나눠서 각각의 완전 무게 분포를 구하였으며, 이때 이미 알려진 이 부호의 부분 부호의 지수합 분포 및 이진 무게 분포를 이용하였다. 이 결과와 MacWilliams 항등식을 이용하여 Z$_4$상에서 정의된 Goethals 부호의 완전 무게 분포를 쉽게 구할 수 있다. 또한 이 결과는 Goethals 부호와 Delsarte-Goethals 부호에서 3-design을 찾는데 이용되었다.

There has been a recent growth of interest in codes with respect to a newly defined non-Hamming metric grown as the Rosenbloom-Tsfasman metric (RT, or $\rho$, in short). In this paper, the definitions of the Lee complete $\rho$ weight enumerator and the exact complete $\rho$ weight enumerator of a code over $M_n_\times_s(Z_4)$ are given, and the MacWilliams identities with respect to this RT metric for the two weight enumerators of a linear code over $M_n_\times_s(Z_4)$ are proven too. At last, we also prove that the MacWilliams identities for the Lee and exact complete $\rho$ weight enumerators of a linear code over $M_n_\times_s(Z_4)$ are the generalizations of the MacWilliams identities for the Lee and complete weight enumerators of the corresponding code over $Z_4$.

We study codes over the polynomial ring ${\mathbb{F}}_q[D]$ and their projections to the finite rings ${\mathbb{F}}_q[D]/(D^m)$ and the weight enumerators of self-dual codes over these rings. We also give the formula for the number of codewords of minimum weight in the projections.

Gestational age and infant birth weight are influenced by gestational weight gain. This study was aimed to examine the effects of gestational weight gain on pregnancy outcomes. Pregnant women were recruited at two hospitals in Seoul area. Characteristics and dietary intakes of pregnant women were obtained using 24-hour recall questionnaires. Gestational weight gain was categorized as less (Under-gain) than, within (Recommended gain), or greater (Over-gain) than the Institute of Medicine guidelines. Maternal height and pre-pregnancy weight in the over-gain group significantly higher than under-gain and recommended gain group. Mini dietary assessment score of eating bean has significantly higher in under-gain group than recommended gain group and eating kimchi has significantly higher in undergain group than over-gain group. Score of eating fruit was significantly higher in over-gain group than other groups. The mean intake of carbohydrate in the recommended gain group were significantly higher than under-gain group, and mean intake of potassium in the over-gain group were significantly higher than under-gain group. Under-gain group showed the high rate of the preterm delivery and low birth weight infant delivery. However recommended gain group showed 46% reduced risk of preterm delivery (OR = 0.54 CI = 0.30-0.98). Risk of macrosomia increased with increasing gestational weight gain (p for trend < 0.05). In conclusion, pregnancy outcomes were influenced by gestational weight gain. Therefore, these finding suggested adequate gestational weight gain according to BMI for reducing the risk of preterm delivery, low birth weight and macrosomia.

Over-weight vehicles give the structure of the road an impact overly and shorten the life of the pavements. But unfortuntely so far there has been no clear regulation to implement over weight vehicles. So I suggest that the fining should be evaluated differently according to the size of axle loads. In addition I adapt our study to Pusan city and propose an adequate regulation against over weigtht vehicles.
