  • Purpose: The purpose of this study was to analyze the changes of parameters of foot contact by various carrying a pack methods during walking. Method: The subjects were consisted of normal forty four persons (males 30, females 14, mean age 23). The carrying a pack methods were classified into five conditions: carrying no bag(Con 1), carrying a backpack(Con 2), carrying a shoulder bag(Con 3), carrying a cross bag(Con 4), carrying a one-hand bag(Con 5). All subjects were participated in these five condition and measured foot pressure by F-scan system during walking. Then foot contact time, foot contact area, foot contact length and width were measured and analyzed. The repeated one-way analysis of variance (ANOVA) was used to get difference between conditions and independent t-test was used to get difference between left and right foot within condition. Result: In the comparison of parameters of foot, contact time, contact area and mid foot width were significantly different between conditions(p<.05), and in both foot contact time at condition 5 showed the most significant reduction(p<.05). In the comparison of parameters of foot between left and right foot within condition, every conditions were not significantly different(p>.05). Conclusion: In this study various carrying methods changed the parameters of foot contact and showed significant difference in some articles between carrying methods. However, asymmetric load of pack by carrying methods didn't affected symmetry of parameters of foot contact between left and right foot.

  • PURPOSE: This study examined the effect of using a smartphone according to the direction of wearing a bag on muscle characteristics and balance ability in adults in their 20s with chronic ankle instability. METHODS: Twelve people with chronic ankle instability were examined for three weeks. The types of carrying a bag were classified into three conditions: to the right, to the left, and on both sides. The muscle characteristics and balance ability were measured and analyzed. The one-way ANOVA was used to obtain a difference between conditions. RESULTS: A significant difference in the muscle tone of medial gastrocnemius was observed between the dominant group and the non-dominant group. The muscle tone and stiffness of the peroneus longus decreased significantly after walking with a smartphone and carrying a bag. The maximum slope of the forward and reverse directions increased and decreased significantly, respectively, after walking with a smartphone and carrying a bag on both sides. CONCLUSION: In this study, muscle fatigue causes a decrease in muscle tone and stiffness with chronic ankle instability when carrying a heavy back while walking, and there were asymmetric changes in the balance ability. Therefore, adults with chronic ankle instability should carefully avoid carrying a heavy bag for extended times, irrespective of the style or type of the bag.

  • Objective: Children with spastic diplegic cerebral palsy show weakness especially in the lower-extremity rather than upper-extremity muscles and display characteristics such as asymmetric alignment, deficits in postural control or balance ability, and slow walking speed. Various therapeutic interventions are applied to children with cerebral palsy, of which taping is widely used in the field of rehabilitation, however, there are few studies of the effects of kinesio taping on gait patterns of children with cerebral palsy. The present study investigated the effects of kinesio taping on gait parameters of children with cerebral palsy. Design: Cross-sectional study. Methods: Four children with spastic diplegia participated in this study. The participants' gait parameters while walking 10 m with and without kinesio taping (tibialis anterior, quadriceps femoris, and gluteus maximus) were recorded. Gait parameters including gait velocity, cadence, step length, stride length, single support time, and double support time were evaluated using the GAITRite. Mean values were obtained after having the subjects walk three times in each condition with a 5-minute rest period between each condition. The order of each condition was assigned randomly. Results: There were significant improvements in gait velocity, step length, stride length, and single support time of the right leg with kinesio taping condition compared to the without kinesio taping condition taping (p<0.05). However, there were no significant differences in cadence, single support time of the left leg, or double support time. Conclusions: The results show that kinesio taping may have a positive effect for improving gait parameters of children with spastic diplegia. However, its usefulness in the rehabilitation of children with cerebral palsy needs to be further investigated.

  • Electron spin resonance (ESR) spectroscopy was used to investigate the effect of irradiation dose on the ESR signal intensity of irradiated crabs and the stability of these radicals under 9 weeks of storage. Swimming and small crabs were irradiated with doses of 0, 1, 3, 5 and 7 kGy using a Co-60 irradiator at ambient temperature. A claw, a walking leg and a cars- pace of the crab pieced and dried were placed in a resonant quart tube within an EPR X-band spectrometer. The irradiated crabs presented an asymmetric absorption in shape at g$_1$=2.002 $\pm$ 0.003 and g$_2$=1.998$\pm$0.005, and were different from the non-irradiated ones. The intensity of the ESR signals was greatest in the claw, intermediate in the carapace and lowest in the walking leg. Samples given low and high doses of irradiation could also be distinguished. The ESR signal after irradiation was stable, even after a 9-week storage.

  • The purpose of this study was to identify the factors determining the participation restriction of chronic stroke patients based on international classification of functioning, disability, and health (ICF) model. Sixty-eight stroke patients participated. The participants were assessed participation restriction using the Korean version of London handicap scale (K-LHS), modified Barthel index (K-MBI) to measure activities of daily living, Berg balance scale (K-BBS) to assess balance, and the center for epidemiologic studies depression (K-CES-D) to gauge depression. Also, 3 minutes walking test (3MWT), gait velocity, asymmetric posture, and family support were assessed. A stepwise multiple regression analysis was used to explore the factors determining participation restriction. There were no significant different in the K-LHS and K-MBI results by gender (p>.05). Correlations between the K-LHS and K-MBI (r=-.656), K-BBS (r=-.543), K-CES-D (r=.266), 3MWT (r=-.363), gait velocity (r=.348), and family support (r=-.389) were significant (p<.05). Also, the K-MBI and family support were the factors that determined participation restriction (p<.05) and that 40.2% of the variation in the K-LHS can be explained. Therefore, it is suggested that evaluation and intervention of patient's activity level and extent of family support is necessary to reduce participation restriction of chronic stroke patients.

  • The works of the Futurism were developed along with manifestos and statement in publishing. Futurist aesthetic and ideological agenda on futurist fashion displayed in manifestos on clothes. Futurist fashion propagated in consummate Futurist style through the written manifesto. The Futurists anticipated much of modern fashion phenomenon. In Futurist Men's Clothing, men's clothing is aggressive, agile, dynamic, simple and comfortable, hygienic, gay, luminous, volatile, asymmetric and variable. In Futurist Manifesto on Woman's Clothing, woman is now a principal agent of revolt, a walking synthesis of the audacious, performance-oriented aesthetic of the futurist universe. For Futurist woman's clothing they claimed ingenuity, daring, and economy. The Futurist Manifesto of Italian Hat was continued with their provocative style and radical ambition. Their innovation will rescue a lagging Italian expert and restore the Italian male to his former Iatin Vigor. Speed, dynamic, utility, and funtionality are the main characters. In Futurist Manifesto of Italian Cravat, Futurist cravat is called Anti-cravatta, which is anti-traditional style and made of unconventional materials. In general, the Futurist argued for clothes that promoted simple and functionality. These Futurist fashion project were invention of the new style, avant-garde style, in daily wear and were realized for the renewal of taste in clothing design as a modernizing factors.

  • Purpose: This study was conducted to predict the risks that arise while standing on mediolateral ramps at various ramp angles by identifying the ratio of medial to lateral gastrocnemius muscle activities. Methods: The subjects were 20 healthy adult men. Seven mediolateral ramp angles ($0^{\circ}$, $2^{\circ}$, $5^{\circ}$, $10^{\circ}$, $15^{\circ}$, $20^{\circ}$, and $25^{\circ}$) were applied for the experiment. The ratio of medial to lateral gastrocnemius muscle activities in each condition was measured using electromyography, and the measured data were converted to root mean square values to calculate the activity ratios. Results: The study results showed statistically significant differences in the ratio of mediolateral gastrocnemius muscle activities according to the selected mediolateral ramp angles. The results of a post hoc test confirmed that the multifidus muscles were asymmetrically used on the two sides at mediolateral ramp angles of $5^{\circ}$ or higher. Conclusion: This study found that an asymmetric use of the multifidus muscles began at a mediolateral ramp angle of $5^{\circ}$, and the provision of propulsion using the ankle joints on mediolateral ramps at $5^{\circ}$ or steeper was maneuvered differently from that on flat ground. This suggests that individuals with balance control disorder have the risk of falling due to ankle sprains and unstable balance control. Therefore, patients and elderly people are required to exercise caution when crossing $5^{\circ}$ or steeper ramps.

  • Mycophenolic acid (MPA) is an antibiotic produced by Penicillium brevicompactum. MPA has antifungal, antineoplastic, and immunosuppressive functions, among others. ${\beta}-Hydroxy-{\beta}-methylglutaryl-CoA$ (HMG-CoA) lyase is a key enzyme in the bypass metabolic pathway. The inhibitory activity of HMG-CoA lyase increases the MPA biosynthetic flux by reducing the generation of by-products. In this study, we cloned the P. brevicompactum HMG-CoA lyase gene using the thermal asymmetric interlaced polymerase chain reaction and gene walking technology. Agrobacterium tumefaciens-mediated transformation (ATMT) was used to insert a mutated HMG-CoA lyase gene into P. brevicompactum. Successful insertion of the HMG-CoA lyase gene was confirmed by hygromycin screening, PCR, Southern blot analysis, and enzyme content assay. The maximum MPA production by transformants was 2.94 g/l. This was 71% higher than wild-type ATCC 16024. Our results demonstrate that ATMT may be an alternative practical genetic tool for directional transformation of P. brevicompactum.
