The teacher's role scale for improving young children's creativity is designed for both teacher self-rating and observer rating. Content validity was determined by 5 experts who defined the domains of specific content. Construct validity was obtained by the self-ratings of 404 teachers of 3- to 5-year-old children. Five factors using 38 items of the original 59 were found to be related to the teacher's role in improving young children's creativity. The factors were Indulgence and Perseverance, Flexibility, Originality, Elaboration, and Fluency. Convergent validity was confirmed by positive correlations of the Teacher's Role Scale with the Teacher's Creativity Test of the Korean Institute for Research in the Behavioral Sciences. For internal consistency, Cronbach ${\alpha}$ of the 5 factors ranged from .74 to .88. Test-retest reliability coefficientents ranged from .653 to .838. These results confirm the Scale as a valid and reliable measure of the teacher's role in improving the creativity of young children.

Purpose: This study was done to analyze the effects of Tai Chi on fall-related risk factors through meta-analysis of randomized clinical trials published in English and Korean between 2000 and 2010. Methods: Using health related database and hand search of references and Google, 28 randomized studies were collected from doctoral dissertation and published peer reviewed articles. The Comprehensive Meta-analysis version 2.0 was used for the analysis. Results: The effect sizes for Tai Chi for 3 months were significant with ES=0.54 for static balance, ES=0.24 for dynamic balance, ES=0.69 for balance measured by scale, and ES=0.40 for flexibility, ES=0.48 for muscle strength, ES=0.71 for ADL, and ES=0.37 for fear of falling. Also, the effect sizes of Tai Chi for 6 months were significant for most fall-related variables. The 6 month data for flexibility was not analyzed since only one study was published. Conclusion: The analysis of studies of randomized clinical trials indicate that Tai Chi is effective in improving balance, flexibility, muscle strength, activities of daily living, and fear of falling when applied for 3 or 6 months. The findings provide the objective evidence to apply Tai Chi as a fall preventive intervention.

This study evaluates the objective and subjective hand as well as the preference for hand and outdoor jackets on laminated waterproof breathable fabrics with different constituent characteristics to identify those best suited for consumer needs. Mechanical properties and objective hands were measured by the KES-FB system. The subjective hand and the preference of laminated waterproof breathable fabric for outdoor jackets were rated by the 20's and 30's women experts with tactile and visual senses that utilized a questionnaire with a seven-point semantic differential scale; subsequently, the flexibility and compressive elasticity of laminated waterproof breathable fabrics were low. However, light and thin waterproof breathable fabrics with a smooth surface had high scores in smoothness, fullness & softness and total hand value. In addition, laminated waterproof breathable fabrics were classified into three hand factors: flexibility, density, and surface properties. There were significant differences on flexibility and surface property perceptions, hand and out-door jackets preferences according to the characteristics of waterproof breathable fabrics. The hand preference of the laminated waterproof breathable fabric improved with decreasing 2HB and increasing EM. However, EM showed positive effect for outdoor jacket preferences. Those that were flexible and smooth were preferred for outdoor jackets.

Purpose: The purpose of this study was to determine the effects of a Health Maintenance Program on physical functions and mental health of the elderly in nursing homes. Method: Sixty elderly(over 65 years old) in a randomized control study participated in a 16-week group-based intervention including functional exercises and health education. The participants were divided into 3 groups(Health Maintenance Program Group, Supportive Music Exercise Group, and Control Group) of 20 elderly each. Data was collected from Dec. 1st, 2005 to Mar, 30th, 2006. Physical function of lower body strength was assessed using a 30-second chair test, flexibility was assessed using a sit-and-reach test, and static balance was assessed by the ability to balance on one leg with open and closed eyes. Depression was assessed using the Korean Form of the Geriatric Depression Scale and self esteem was assessed using Rosenberg's Self Esteem Questionnaire. Data was analyzed by Chi-square test, One-way ANOVA, and Repeated measure two factor analysis. Results: A Health Maintenance Program significantly increased muscle strength, flexibility and static balance, but depression and self-esteem scores were not significantly changed. Conclusion: Findings demonstrated that a Health Maintenance Program was more effective on physical function than mental health of the elderly in nursing homes.

Purpose: This research was implemented for men in their thirties who have lower back pain to observe general activity disorder patterns during pinch lift and rubbing manual therapy (PMT) and stretching application. Methods: Participants were divided into three groups: The PMT Group used applied pinch lift and rubbing manual therapy; the STR Group used applied stretching; and the CON Group was the control group. Participants for each group received treatments that were conducted three times a week for a total five weeks. Measures of pain utilized Visual Analogue Scale (VAS) [INCOMPLETE SENTENCE]. Results: There were significant differences between the PMT Group and the CON Group as well as the STR Group and the CON Group for pain, muscle strength and flexibility. There was a significant difference in pain between the PMT Group and the STR Group. Conclusion: As a result, it is inferred that PMT and stretching positively influenced recovery with regards to pain, muscle strength and flexibility relief; however PMT is more effective for pain relief than stretching.

The purpose of this study was to evaluate effect of balance control therapy on low back pain patient's pain and flexibility. The subjects were consisted of 45 patients (15 males, 30 females) who had limited flexion range of motion of full spine with low back pain. All patients were one time treated the balance control therapy. Visual Analogue Scale(VAS) and Finger-to-Floor test(F-T-FT) were measured at pre-treatment, post-treatment and next day. VAS was used to measure subjective pain level. F-T-FT was used to measure forward flexion range of motion of full spine of low back pain patients. The results of this study were summarized as follow: 1. The VAS was significantly reduced between pre-treatment, post-treatment and next day (p<0.001). 2. The F-T-FT was significantly reduced between pre-treatment, post-treatment and next day (p<0.001). 3. The changes of pain decrease were related with pain duration(p<0.05), satisfaction for previous treatment(p<0.001). 4. The changes of flexibility increase were related with satisfaction for previous treatment(p<0.05).

Coordinating operation between large-scale wind power and thermal units in multiple time scale is an important problem to keep power balance, especially for the power grids mainly made up of large coal-fired units. The paper proposes a novel operation mode of multi-scale unit commitment (abbr. UC) that includes mid-term UC and day-ahead UC, which can take full advantage of insufficient flexibility and improve wind power accommodation. First, we introduce the concepts of multi-scale UC and then illustrate the benefits of introducing mid-term UC to the wind-coal intensive grid. The paper then formulates the mid-term UC model, proposes operation performance indices and validates the optimal operation mode by simulation cases. Compared with day-ahead UC only, the multi-scale UC mode could reduce the total generation cost and improve the wind power net benefit by decreasing the coal-fired units' on/off operation. The simulation results also show that the maximum total generation benefit should be pursued rather than the wind power utilization rate in wind-coal intensive system.

A field study of wind-induced internal pressures in a flexible and porous industrial warehouse with a single dominant opening, of various sizes for a range of moderate wind speeds and directions, is reported in this paper. Comparatively weak resonance of internal pressure for oblique windward opening situations, and hardly discernible at other wind directions, is attributed to the inherent leakage and flexibility in the envelope of the building in addition to the moderate wind speeds encountered during the tests. The measured internal pressures agree well with the theoretical predictions obtained by numerically simulating the analytical model of internal pressure for a porous and flexible building with a dominant opening. Ratios of the RMS and peak internal to opening external pressures obtained in the study are presented in a non-dimensional format along with other published full scale measurements and compared with the non-dimensional design equation proposed in recent literature.
