Purpose: The purpose of this study was to evaluate the effectiveness of three functional performance tests and one-legged hop test and to establish the reference data of the three functional performance tests of the active young Korean men. Materials and methods: We performed five tests on 40 normal subjects such as one-legged hop test (single hop, triple hop) and the three functional performance tests (carioca test, co-contraction test, shuttle run test). The mean age was 28.4 years. The mean score of Tegner activity scale was 6.2 and Lysholm score 98.2 Mean value and standard deviation were obtained. The correlation of age, height and weight with the results, the relationship between FPT and one-legged hop test and the mean difference between dominant and non-dominant limbs were statistically calculated. Results: All data obtained were normally distributed and there were no significant relationship between age, height and weight. The paired t-test of one legged hop test showed no statistical significance between dominant and non-dominant limbs. The results of one legged hop test had strong relationship with functional performance test. Conclusion; The three functional performance tests can be a useful functional test in ACL-insufficient athletes. Our results can be used as normal reference data of the normal active Korean men.

Effects of air pollutants on the chemical properties of soil in Yoch'on inductrial complex were investigated. Soil pH showed severe acidity with average value of 4.3$\pm$0.13. Soil pH decreaed along the increase in altitute of Mt. Jeseok. Soil organic matter and total N was 19.2$\pm$3.6% and 4.7$\pm$0.25mg/g, respectively, which were higher than those of unpolluted area, Kongju. Available P was 41.2$\pm$3.7 $\mu$g/g, which was 4 times greater than that of unpolluted area, Kongju. Average content of total-S was 283.5$\pm$14.1 $\mu$g/g, which was 10 times greater than that of unpolluted area. Content of available Al was o.43$\pm$0.03 mg/g, which was 2 times greater than that of unpolluted area. Available Al increased as the soil pH decrease. Contents of exchangeable K, Ca and Mg were significantly lower than those in unpolluted area, because of severe leaching in acid soil.

Weight loss and nutrient dynamics of Quercus mongolica leaf litter during decomposition were investigated from December 2005 through August 2008 in Mt. Worak National Park as a part of National Long-Term Ecological Research Program in Korea. The decay constant (k) of Q. mongolica litter was 0.26. After 33 months decomposition, remaining weight of Q. mongolica litter was 49.3 ± 4.4%. Initial C/N and C/P ratios of Q. mongolica litter were 43.3 and 2,032, respectively. C/N ratio in decomposing litter decreased rapidly from the beginning to nine months decomposition, and then showed more or less constant. C/P ratio increased to 2,407 after three months decomposition, and then decreased steadily thereafter. N and P concentration increased significantly during decomposition. N immobilization occurred from the beginning through 18 months decomposition, and mineralization occurred afterwards in decomposing litter. P immobilized significantly from fifteen months during decomposition. K concentration decreased rapidly from the beginning to six months decomposition. However it showed an increasing pattern during later stage of decomposition. Remaining K decreased rapidly during early stage of decomposition. There was no net K immobilization. Ca concentration increased from the beginning to twelve months decomposition, and then decreased rapidly till twenty one months elapsed. However, it increased again thereafter. Ca mineralization occurred from fifteen months. Mg concentration increased during decomposition. There was no Mg immobilization during litter decomposition. After 33 months decomposition, remaining N, P, K, Ca and Mg in Q. mongolica litter were 79.2, 110.9, 36.2, 52.7 and 74.4%, respectively.

Purpose: This study is to compare the medial longitudinal arch between heel pain group and normal painless group. Materials and Methods: Heel pain group 242 feet and normal group 140 feet were evaluated through the radiographic images of standing foot-ankle lateral view. Four radiographic indices, talo-1stmetatarsal angle (TMA), calcaneal-1st metatarsal angle (CMA), calcaneal pitch angle (CPA), and arch ratio (AR), were used as well as BMI. Results: There was no difference between heel pain group and normal group in the TMA, CMA, CPA, and AR. But in the BMI, heel pain group showed $1.7\;kg/m^2$ (p=0.0002) higher than normal group. To eliminate the sexual error, male and female were evaluated separately. Male heel pain group showed 2.9 degrees more dorsiflexion (p=0.001) in the TMA, 3.1 degrees greater (p=0.007) in the CMA, 0.01 lower (p=0.028) in the AR, and $1.0\;kg/m^2$ greater (p=0.033) in the BMI than normal male group. There were no difference in the CPA. Female heel pain group showed 3.6 degree greater (p=0.035) in the CMA, and $1.9\;kg/m^2$ greater (p=0.002) in the BMI than normal female group. But other indices demonstrated no differences. Conclusion: talo-$1^{st}$ metatarsal angle, calcaneal-$1^{st}$ metatarsal angle and arch ratio were radiographic indices related with heel pain.
