Purpose: The purpose of this study was to examine the effects of static stretching and Evjenth-Hamberg stretching on isokinetic muscle strength of knee flexors and extensors. Methods: The subjects were composed of eighty healthy males without weight-training experience. ROM of knee joint measured active maximal extension and isokinetic Peak Torque measured $60^{\circ}/sec,\;120^{\circ}/sec$ using an the En-Knee. Three tests(Baseline, 4 weeks, 8 weeks, respectively) was operated to examine change of each variable. Data were analyzed with a $2{\times}3$ analysis of variance ($group{\times}test$) for repeated measures on last factor by SPSS package 10.0. The data analysis revealed muscle strength were dependent on stretching method. Results: The results were as follows. First, Evjenth-Hamberg stretching(E-HS) was more effective than static stretching(SS) on ROM. Second, Peak Torque of knee flexors and extensors was improved in both methods by each time. but E-HS was more improved than SS. Conclusion: In conclusion, This study indicates that E-HS is more efficient than SS on muscle strength improvement.

This paper introduces a probabilistic analysis method in order to analyze the effect of manufacturing tolerance on induction motor performance occurring in massive production. The univariate dimension reduction method is adapted to predict probabilistic characteristics of a performance function due to certain probabilistic distributions of design variables. Moreover, the sensitivity information on mean and variance of the performance function is estimated, and then the effect of randomness of individual design variables on the probability performance function is analyzed. The effectiveness and accuracy of the method is investigated with a mathematical model and an induction motor.

Various effluents generated in cooking processes contribute a great deal to indoor air pollution among many other indoor pollutants such as dusts from outdoor and carbon dioxide from human body. Kitchen exhaust hoods are not believed to exhaust indoor contaminants properly in many cases, while generating too much noise. Instead of focusing on individual products of kitchen hoods, we should address the problem by attacking the ventilation system as a whole including vertical shafts and building air-tightness. In this study, it is intended to investigate the pressure distribution along the vertical shaft depending on various system parameters, such as shaft size, concurrent hood usage rate, roof fan, inlet pressure loss, and outdoor temperature. The maximum static pressure in the vertical shaft has been obtained using the method of design of experiments and analyzed by the analysis of variance. The results can be used for the design of kitchen exhaust systems by analyzing the pressure distributions in vertical shafts.

The purpose of this study was to investigate the sensation seeking tendency and knitwear purchase behaviors of high school girls. The data were obtained from 475 high school girls at 6 high schools located in Daejeon. The method of study is a survey consisted of sensation seeking tendency items, knitwear purchase behavior items and demographic attribution. Data were analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS WIN 17.0 program. The results of study are as follows. First, high school girls generally liked knitwears by reason of comfort and activity. Most girls purchased the knitwears to wear ordinary casual wear(81.5%). They usually thought sweater and cardigan to be representative of knitwears. Also, they mostly purchased the knitwears of simple and active design, achromatic color, 100% cotton, and solid or simple stripe pattern. The design and price were considered as important evaluation criteria in knitwear purchase. The information sources used by them were store display, friends, and internet. Second, the knitwear purchase behaviors of high school girls showed the difference between groups with high- and low-sensation seeking tendency. The most important factor of knitwear purchase was an unique and characteristic design in high group and a simple and active design in low group. In conclusion, high school girls liked knitwears and had different knitwear purchase behaviors according to the sensation seeking tendency.

Purpose: The purpose of this study is to construct and test a structural equation model of posttraumatic growth (PTG) of earthquake victims based on Tedeschi and Calhoun's model (2004). Methods: Data were collected from 195 earthquake victims living in K. City. The exogenous variables include distress perception, resilience, and social support, and the endogenous variables include intrusive rumination, deliberate rumination, and posttraumatic growth. For data analysis, descriptive statistics, factor analysis, and structural equation modeling were performed. Results: The modified model showed a good fitness to the data. Moreover, 6 of the 9 paths of the final model were statistically significant, which include PTG affected by deliberate rumination (${\beta}=.58$, p<.001), resilience (${\gamma}=.18$, p=.001), and distress perception (${\gamma}=.20$, p=.002). These predictors explain 51.8% of variance in posttraumatic growth. Conclusion: Based on the results of this study, it is necessary to develop and disseminate preventive intervention programs to increase the resilience of earthquake-prone communities. In addition, after exposure to a community-scale traumatic event such as earthquake, we should provide social supports to alleviate distress perception and transition from intrusive rumination to deliberate rumination so that we can seek new meaning from the earthquake and facilitate posttraumatic growth.
