The purpose of this study was to investigate the relationship among spatial ability, learning styles, visual-perception- recall abiltiy, and the conceptual construction of the earth and moon's motion. Four paper-and-pencil tests were used to measure students' cognitive variables. Spatial ability was measured by Spatial Visualization Test, visual-perception-recall ability was measured by Rey's Figure which also have used to test visual- perception-recall ability of right-temporal lobes, and VVT were used to investigate students' learning styles. further, the test of concept construction was consisted of 15 items about the earth and moon's motion developed by researcher One hundred and twenty-seven 6th-, one hundred and sixteen 7th-, eighty-seven 9th-grade, ninety-three college students were participated in the investigation of the effects of age and learning style on conceptual construction. In the analysis of students' performances, spatial ability, visual-perception-recall ability, and conceptual achievement showed an increasing pattern with grading. In addition, visual learner's conceptual achievement showed a significantly higher score on conceptual test than verbal learner's(p<0.05). The results of the present study supported tile hypothesis that learning styles would differently influence to learning atmospheric concepts by students'learning styles. This study also indicated to be considered the students' spatial ability in learning atmospheric concepts.

Purpose: To improve pulmonary function and decrease in balance ability with increasing forward head position and vertebral curvature, we applied Figure-8 brace to confirm the immediate effect on vital capacity and balance and to see if it is applicable. Methods: A total of 34 elderly women aged 65 or older and young women in their 20s with FHP were screened to measure vital capacity, measuring the forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), and measuring the foot pressure to see the change in balance. For statistical analysis, the difference between pre and post values was compared using pared t-test. Results: As a result of vital capacity measurements, there was no significant difference between FEV1 and FVC for women over 65 years old (p>0.05). Young women in their 20s had no significant difference in FEV1 (p>0.05), and FVC had significant differences (p<0.05). In measuring foot pressure to measure balance, both women aged 65 and above and young women in their 20s had a significant decrease in anterior foot pressure, and a significant increase in posterior foot pressure (p<0.05). Conclusion: The results of this study did not positively affect the vital capacity of elderly women with FHP. However, the significant increase in vital capacity of young women in their 20s suggests that contraction of the abdominal muscle is necessary during forced expiration. Therefore, it is believed that proper application and therapeutic interventions should be combined when applying Figure-8 brace.

The purpose of this study was to examine the appearance management motives and body image perception according to males' appearance management behavior. A set of questionnaire was administered to 398 male consumers. Data were analyzed by utilizing frequency, factor analysis, ANONA, cluster analysis, and crosstabs. Factor analysis of body image perception extracted four factors such as appearance concern, appearance satisfaction, exercise ability, and weight control. Four groups of the appearance management behavior were classified into such as health oriented, active figure management, indifference to personal appearance, and fashion/skin care by cluster analysis. All groups pursued sociality in appearance management motives. The active figure management group showed highest concern about in all the appearance management motives and body image perception.

Purpose: In real life there are both straight-paths and curved-paths. To evaluate walking ability of both kinds, a figure-8 walking test (F8WT) was developed. The aim of this study was to validate the measure in hemiplegic patients with walking difficulties and to identify correlations of curved walking ability with straight walking ability, motor function, and walking performance ability. Methods: Twenty subjects participated in this study. Curved walking was measured by a F8WT. Straight walking ability was measured by a 10-meter walking test (10MWT). Dynamic balancea bility was measured by timed up and go (TUG) tests. Walking performance ability was measured using a modified motor assessment scale (MMAS). Motor function was measured by the Fugl-Meyer assessment (FMA) scale. Data were analyzed using Pearson correlation analysis. Linear regression analyses were performed to explore other functional tests in mobility ability by F8WT time, 10MWT (dependent variable). Results: There was a significant positive correlation of F8WT time with 10MWT and TUG. There was a significant negative correlation of F8WT time with MMAS and FMA-coordination. There was a significant positive correlation of 10MWT with TUG. There was a significant negative correlation of 10MWT with MMAS and FMA-coordination. The F8WT time for curved walking ability was attributed to 10MWT for straight walking ability as 94% level of contribution. Conclusion: The results suggest that the F8WT is a good instrument for measuring walking ability because there is a robust correlation of F8WT time with 10MWT, TUG, MMAS, and FMA-coordination in hemiplegic patients who, after stroke, have a mobility deficiency.

This research is to figure out how people recognize and perceive on cosmetic attributions of imported brand and domestic brand. In other words, we are trying to analyze the brand images and figure out how they are different in demographic perspective. For this research, this research has been fulfilled from September 20th 2011 to November 5th. We have surveyed women with age between 20's to 50's. With 477 data, we have analyzed by using SPSS 18.0 Version of statistic package. We have used frequency analysis, t-test and one way ANOVA (chi-square test) for data processing method. By comparing and analyzing the 16 attribute types of imported and domestic cosmetics, there were no attention difference on 7 questionaries' but there were attention difference on 9 questionnaires'. 5 questionaries' which show higher recognition on domestic brand of cosmetic than imported brand were shown. 4questionaries' which show higher recognition on imported brand of cosmetic than domestic brand were shown. By examining the different recognitions between domestic brand and imported brand of cosmetics in demographic perspective, it did not show any attentive difference on domestic brand by district residence, age, academic ability, marriage, occupation and monthly income average. But it showed attentive difference on imported cosmetic brand. It showed that people who live in capital region, with younger age and who have not been married have high rate of preference on imported cosmetic brand. It also showed that people who have higher academic ability and with higher monthly income average have high rate of preference on imported cosmetic brand. Especially, specialized job showed highest preference.

PURPOSE: The aim of the present study was to determine whether high frequency repetitive transcranial magnetic stimulation (rTMS) can improve balance ability in acute stage stroke patients. METHODS: The study was conducted on 30 subjects diagnosed with hemiparesis caused by stroke. The experimental group consisted of 15 patients that underwent rTMS for 15 mins and the control group consisted of 15 patients that underwent sham rTMS (for 15 minutes). A 70-mm figure 8 coil and a Magstim Rapid stimulator was used in both groups. Patients in the experimental group received 10 Hz rTMS applied to the hotspot in the lesioned hemisphere in 10-second trains with 50-second intervals between trains, for 15 minutes (total 2,000 pulses). Both groups received conventional physical therapy for 30 minutes a day, 5 days a week, for 4 weeks. Static balance ability analysis was performed using the Gaitview system to measure pressure rate, postural sway, and total pressure, and dynamic balance ability analysis was performed to measure pressure variables using a balance system. RESULTS: A significant difference was observed in post-training gains for pressure rate, total pressure in static balance, and overall stability index in dynamic balance between the experimental group and the control group (p<.05). CONCLUSION: The results of this study indicate that high frequency rTMS may be beneficial for improving static and dynamic balance recovery in acute stroke patients.

Analogy, based on a similarity, is to infer the properties of the similar object from properties of an object. It can be a very useful thinking tool for learning mathematical patterns and laws, noticing on relational properties among various situations. The purpose of this study, when manipulating hint condition, figure and table conditions and the amount of original learning by using algebra word problems, is to verify the effects of analogical transfer in solving equivalent, isomorphic and similar problems according to the similarity of source problems and target ones. Five study questions were set up for the above purpose. It was 354 first grade students of S and G middle schools in Seoul that were experimented for this study. The data was processed by MANOVA analysis of statistical program, SPSS 10.0. The results of this studies would indicate that most of the students would be poor at solving isomorphic and similar problems in the performance of analogical transfer according to the similarity of source and target problems. Hints, figure and table conditions did not facilitate the analogical transfer. Merely, on the condition that amount of teaming was increased, analogical transfer of the students was facilitated. Therefore, it is necessary to have students do much more analogical problem-solving experience to improve their analogical reasoning ability through the instruction program development in the educational fields.
