The purpose of this study was to investigate the effect of a Kabaddi exercise to metabolic hormone and immune function in male college students. During the experiment 14 men were selected and tested. The subjects were randomly assigned to a control (CON: n=7) or a raining group (TR: n=7) group. A total of 2 blood samples were collected before and after 12 weeks of exercise. First, insulin was significantly decreased while glucagon was increased but did not show any significant change in the strength group. On the other hand, insulin was increased and glucagon was decreased, indicating no significant change in the control group. Second, there were significant increases in the neutrophils and lymphocytes, while there was increases in the monocyte counts but not significant change. On the other hand, neutrophils and lymphocytes were increased, while monocyte counts was decreased but did not show any significant changes in the control group. Third, immunity globulin was significantly increased in IgA, while it was increased in IgG and IgM but not significant. On the other hand, there were increases in IgA, IgG and IgM but not significant changes in the control group. Based on the results from the experiment, the Kabaddi exercise program resulted in a decrease in insulin and an increase in neutrophils and lymphocytes. It is expected to enhance the control of blood sugar, speed of muscle recovery and increase of immunity. It also improved metabolism hormone and immune function.

Nunkeunheugchal (registration No. 01-0001-2014-4), a black waxy giant embryo rice cultivar, was developed by the rice breeding team of National Institute of Crop Science (NICS), RDA in 2012. This cultivar was derived from the cross between get and Josaengheugchal in 2004/2005 winter season, and selected by a promising line, YR25277-B-B-314-2, was selected and designated as the line of Milyang263 in 2009. The local adaptability test of Milyang263 was carried out at four locations from 2010 to 2012 and it was named as Nunkeunheugchal. This variety is a early maturity cultivar. It has 65 cm in culm length and 72 spikelets per panicle, and 1,000 grain-weight of brown rice is 17.8 g which is less than that of Josaengheugchal. This variety is resistant to leaf blast, but susceptible to bacterial blight, neck blast, virus disease and insect pest. The yield potential of Nunkeunheugchal was about 3.54 MT/ha as brown rice at ordinary fertilizer level in local adaptability test for three years. Nunkeunheugchal possesses benefits to rice consumers because of high amounts of GABA, anthocyanin, calcium and iron. This variety would be adaptable to the paddy field of middle and southern plain region of Korea.

The purpose of this study was to find out the influence of 12-week new sports training and music rope jump on the body composition and the physical fitness of elementary students. In this study, 27 students(new sports 14 and music rope jump group 13) were the 3rd grade elementary students in order to examine their body composition(weight, percent body fat, BMI) and physical fitness(cardiorespiratory, muscular strength, muscular endurance and flexibility). The findings of this study were as follows; First, in the body composition, percent body fat significantly decreased in new sports training and music rope jump group. Second, in the physical fitness, muscular strength, muscular endurance and flexibility were significantly increased in new sports training and music rope jump group. The present study indicates that the new sports and music rope jump may improve in physical fitness for elementary students. In addition, new sports training could prevent obesity in elementary students.
