The purpose of this study was to analyze the economic impact of sports event as a part of sports marketing strategies of local city. To reach the purpose, Index of S city for 6 years - number of the sports events, public investment, survey for consumption, and Input-Output analysis. - were researched. S city held most sports event with 8 in 2001 and invested 14.8 million won. The most investment was 39.6 million won with 4 Sports events in 2003. The Production inducing effect reached 2,019 million won in 2001, 3,054 million won in 2002, 3,091 million won in 2003, 538 million won in 2004, 542 million won in 2005 and 1,548 million won in 2006. The highest income inducing effect was 862 million won in 2002 with 7 sports events, the employment inducing effect was calculated to 95 persons in 2002 and 94 persons in 2003, and the valued-added inducing effect was 1,738 million won in 2002. The most economic effects were higher than the average effects of whole other industries in Gangwondo which imply that the in S city held sports events contribute to regional development and more regional sports marketing.

Objectives : To see if there were any differences in waist circumference reduction when certain variable such as age, sex, BFR(BFR; Body Fat Rate), PIBW(PIBW; Percent Ideal Body Weight), WHR(WHR; Waist Hip Ratio) and BMI(BMI; Body Mass Index) were given. Methods : Among outpatients who admitted to department of Oriental Rehabilitation Medicine, Jeon-Ju Oriental Medicine Hospital, Won-kwang University from August 2003 to september 2004, 89 obese patients were chosen and electroacupunture was practiced to these groups in order to treat abdominal obesity and waist circumference reduction. Results : There were no significant correlation between sex, age and waist circumference reduction. Compared to groups who had shown lower BMI, higher BMI groups have shown greater change in waist circumference reduction. As BFR increase waist circumference reduction tended to increase as well. Conclusions : From the above results, higher BMI groups had shown greater change in waist circumference reduction compared to lower BMI groups.
GENERALIZED STABILITY OF ISOMETRIES ON REAL BANACH SPACES
Lee, Eun-Hwi,Park, Dal-Won Korean Mathematical Society 2006 대한수학회보 Vol.43 No.2
Let X and Y be real Banach spaces and ${\varepsilon}\;>\;0$, p > 1. Let f : $X\;{\to}\;Y$ be a bijective mapping with f(0) = 0 satisfying $$|\;{\parallel}f(x)-f(y){\parallel}-{\parallel}{x}-y{\parallel}\;|\;{\leq}{\varepsilon}{\parallel}{x}-y{\parallel}^p$$ for all $x\;{\in}\;X$ and, let $f^{-1}\;:\;Y\;{\to}\;X$ be uniformly continuous. Then there exist a constant ${\delta}\;>\;0$ and N(${\varepsilon},p$) such that lim N(${\varepsilon},p$)=0 and a unique surjective isometry I : X ${\to}$ Y satisfying ${\parallel}f(x)-I(x){\parallel}{\leq}N({\varepsilon,p}){\parallel}x{\parallel}^p$ for all $x\;{\in}\;X\;with\;{\parallel}x{\parallel}{\leq}{\delta}$.

Here in this study, we isolated 1,2,3,4,6-penta-O-galloyl-β-D-glucose (PGG) from Curcuma longa L. and elucidated the lifespanextending effect of PGG using Caenorhabditis elegans model system. In the present study, PGG demonstrated potent lifespan extension of worms under normal culture condition. Then, we determined the protective effects of PGG on the stress conditions such as thermal and oxidative stress. In the case of heat stress, PGG-treated worms exhibited enhanced survival rate, compared to control worms. In addition, PGG-fed worms lived longer than control worms under oxidative stress induced by paraquat. To verify the possible mechanism of PGG-mediated increased lifespan and stress resistance of worms, we investigated whether PGG might alter superoxide dismutase (SOD) activities and intracellular ROS levels. Our results showed that PGG was able to elevate SOD activities of worms and reduce intracellular ROS accumulation in a dose-dependent manner.
Liquefaction Behaviour and Prediction of Deviator Stress for Unsaturated Silty Sand
Lee, Dal-Won The Korean Society of Agricultural Engineers 2006 한국농공학회논문집 Vol.48 No.7
This study was carried out to investigate the liquefaction behaviour and predict deviator stress with matric suction, of unsaturated silty sand. The unsaturated soil tests were conducted using a modified triaxial cell and specimens were prepared using the moisture tamping method. The axis translation technique was used to create the desired matric suctions in the specimen. Undrained triaxial compression tests were carried out at matric suction of 0, 2, 5, 10 and 25 kPa. The specimens were sheared to axial strains of about 20% to obtain steady state conditions. The results showed that liquefaction of silty sand only occurs at matric suction of 0 kPa and 2 kPa. The results also show that at matric suctions of 5, 10 and 25 kPa, the resistance to liquefaction increases. As the suction increases, the undrained effective stress path approached the drained stress path. Also, the predicted and measured maximum deviator stress for unsaturated soils using the effective stress concept showed good agreement as matric suction increases. The deviator stress increase is nonlinear as matric suction increases.

Carbon nanotubes were deposited directly on SUS304 plates by PECVD with acetylene and hydrogen as precursors under various deposition conditions. Raman spectroscopy showed that carbon nanotubes were not fully graphitized at the deposition temperatures, 600 to 750℃, although defects decreased with increase of deposition temperature. SEM microscopy showed that carbon nanotubes were not straight, but their growth followed the tip growth model. Pretreatment of the substrate such as polishing and dipping in HF solution was required for the successful deposition. Using non-aqueous electrolyte we fabricated electrical double layer capacitance (EDLC) with SUS304 plates, on which carbon nanotubes were deposited, without any treatment, and measured charge/discharge characteristics. Discharge capacitance decreased with cycles from initial value of 128 F/g, but stabilized at 58 F/g after 50 cycles.
