Purpose: The purpose of this study was to examine the effects of exercise intervention, including dumbbell(weight lifting), walking, and yoga, on the body composition, physiologic factors, body image, and perceived health in the community-dwelling women. Method: This study utilized pretest-posttest design with three types of exercise interventions. The types of exercise intervention included dumbbell, walking, and yoga. Results: A total of 136 subjects were included: 49 for dumbbell, 67 for walking, and 20 for yoga. As measures of body composition, BMI, body weight, and body fat rate were significantly improved only after dumbbell intervention(p<.01). Systolic blood pressures were significantly decreased in the groups of dumbbell and walking. Diastolic blood pressure was significantly declined only in the walking group. Vital capacities and body image were improved in all groups(p<.01). However, total cholesterol levels were not improved in all groups(p>.05) and none of the measures for perceived health state were not significantly changed in all groups(p>.05). Conclusion: From the findings of this study, it was demonstrated that the effects of exercise interventions were differentiated by their types and variables to be affected. Therefore, future studies that apply the tailored exercise intervention to each age-categorical group are needed.

This study aims to evaluate the differences in visual images due to the variations in the silhouette and jacket type of men's suits. Six samples were used for this study: 3 examples had variations in the silhouette while 2 variations were in the jacket type. They were evaluated using a 7-point rating scale and a survey was conducted among 80 fashion students. The data was analyzed by Factor Analysis, ANOVA, Scheffé Test, and the MCA method. This study's results are as follows: 1) According to Factor Analysis, the components of visual evaluation by the silhouette and the jacket type of men's suit were classified into: attractiveness, masculinity, practicality, and naturalness. Among these factors, attractiveness and masculinity were evaluated to be the most important factors. 2) Men's suits with a single-breasted jacket had a simple and practical images in fitted and boxy silhouettes. Double-breasted jacket suits showed sexy, refined, and chic images in the fitted and slim silhouettes, and expressed an adult, profound, and conservative images in the boxy and fitted silhouettes. 3) The silhouette and the jacket type of men's suit interacted with masculinity and the practicality. Fitted and slim silhouette suits had different images that looked adult, profound, and conservative depending on the jacket type, but the boxy silhouette suit did not show the same effect. 4) According to the MCA on the attractiveness and the naturalness, the jacket type affected the visual image of men's suit more than the silhouette. Double-breasted jacket suits had more sexy, refined, and chic image than the single-breasted jacket suits. Men's suits with a single-breasted jacket had a more comfortable and natural image than those with a double breasted jacket.

The purpose of this study is to investigate the influence of women's life-style on image evaluation of clothing styles, and on their selection of clothing styles by situations. The subject of investigation was 441 women above 20 living in Daegu. 6 types of clothing styles including classic, casual, elegant, dramatic, romantic, and mannish and 7 social situations including shopping near house, shopping in a busy street, cultural center, wedding ceremony, eating out, alumni meeting or fraternity meeting, and couples meeting were used for this study. Data analysis was performed using SPSS package, which included factor analysis, reliability test, cluster analysis, frequency, percentage, ANOVA, and $\chi$$^2$-test. The results are summarized as follows; 1. Adult women could be classified into 5 groups including activist, in-activist, the leisured well-off, the wholesomely economical, and the appearance showing-off by their life-styles. 2. The clothing image according to the 6 clothing styles was different. In the image evaluation of each clothing style by life-style groups, in-active group thought classic style most functional and leisured well-off group, mannish style. Elegant style and dramatic style were estimated positively by the leisured well-off and the appearance showing-off. 3. Selection of clothing style differed according to situations. More formal the situation was, more formal style tended to be selected and for less formal situation, active and mannish style was selected.

This paper aimed to investigate the difference of clothing behavior and desired image according to individualism-collectivism cultural tendency for women. A survey of 217 adult women was conducted from November to December 2006, mainly in Daegu. Reliability, frequency, percentage, factor analysis, ANOVA, t-test, Tukey test and an -analysis were used for data analysis by using SPSS WIN 11.0 package. The results were as follows: First, while the group with a higher tendency toward individualism valued personality and convenience above everything else, the group which has a higher tendency to collectivism disposition has a much greater interested in conformity and brand-orientation. Second, while the group with a higher tendency toward individualism pursued an bold image for their clothing, the group with a higher tendency toward collectivism preferred a feminine and plain image. Third, regarding the individualism-collectivism and demographic peculiarity, there were no significant differences between the two groups according to marital status and average monthly income. However, there were significant differences in individualism-collectivism among the groups determined by age, occupation, educational background and rural or urban background.

We report a case of 29-year-old man diagnosed as a primary eosinophilic granuloma (EG) lesion of the seventh cervical vertebra. He had paresthesia on both arms, and grasping weakness for 10 days. Cervical magnetic resonance image (MRI) showed an enhancing mass with ventral epidural bulging and cord compression on the seventh cervical vertebra. Additionally, we performed spine series MRI, bone scan and positive emission tomography for confirmation of other bone lesions. These studies showed no other pathological lesions. He underwent anterior cervical corpectomy of the seventh cervical vertebra and plate fixation with iliac bone graft. After surgical management, neurological symptoms were much improved. Histopathologic evaluation confirmed the diagnosis of EG. There was no evidence of tumor recurrence at 12 months postoperative cervical MRI follow-up. We reported symptomatic primary EG of cervical spine successfully treated with surgical resection.

Purpose: To make a focal trough (image layer) for an average maxillary dental arch of 6-year-old korean in panoramic radiography. Materials and Methods : Phantom for the maxillary dental arch was designed using intercanine width, intermolar width, tooth size, and interdental spacing to record the data of 6-year-old child. The characteristics of pre-corrected panoramic machine (for adult) was evaluated using the phantom, resolution test pattern for margin of the image layer, and metal ball for the center of the image layer. Panoramic image layer of the child was developed by means of decreasing the speed of film-cassette and positioning the phantom backwards, and then the characteristics of post-corrected panoramic machine (for child) were reevaluated. Results: At post-corrected panoramic image layer, beam projection angles at all interdental areas increased for about 2.6-3.8°, the position of the image layer was shifted toward the rotation center for about 2.5 mm at the deciduous central incisior area. The width of image layer decreased at all areas. Conclusion : Increased beam projection angle will reduce the disadvantage of tooth overlap, and the same form between the center of the image layer and dental arch will improve image resolution.

In this study we analyzed the tendency of the image characteristic by changing filtering factor for the proposed fast non local means (FNLM) noise reduction algorithm with designed Male Adult mesh (MASH) phantom through Geant4 application for tomographic emission (GATE) simulation program. To accomplish this purpose, MASH phantom for human copy was designed through the GATE simulation program. In addition, we acquired degraded image by adding Gaussian noise with a value of 0.005 using the MATALB program in MASH phantom. Moreover, in degraded image, the FNLM noise reduction algorithm was applied by changing the filtering factors, which set to 0.005, 0.01, 0.05, 0.1, 0.5, and 1.0 value, respectively. To quantitatively evaluate, the coefficient of variation (COV), signal to noise ratio (SNR), and contrast to noise ratio (CNR) were calculated in reconstructed images. Results of the COV, SNR and CNR were most improved in image with a filtering factor of 0.05 value. Especially, the COV was decreased with increasing filtering factor, and showed nearly constant values after 0.05 value of the filtering factor. In addition, SNR and CNR were showed that improvement with increasing filtering factor, and deterioration after 0.05 value of the filtering factor. In conclusion, we demonstrated the significance of setting the filtering factor when applying the FNLM noise reduction algorithm in degraded image.

Computed tomography (CT) has the problem of having more radiation exposure compared to other radiographic apparatus. There is a low-dose imaging technique for reducing exposure, but it has a disadvantage of increasing noise in the image. To compensate for this, various noise reduction algorithms have been developed that improve image quality while reducing the exposure dose of patients, of which the median modified Wiener filter (MMWF) algorithm that can be effectively applied to CT devices with excellent time resolution has been presented. The purpose of this study is to optimize the mask size of MMWF algorithm and to see the excellence of noise reduction of MMWF algorithm for existing algorithms. After applying the MMWF algorithm with each mask sizes set from the MASH phantom abdominal images acquired using the MATLAB program, which includes Gaussian noise added, and compared the values of root mean square error (RMSE), peak signal-to-noise ratio (PSNR), coefficient correlation (CC), and universal image quality index (UQI). The results showed that RMSE value was the lowest and PSNR, CC and UQI values were the highest in the 5 x 5 mask size. In addition, comparing Gaussian filter, median filter, Wiener filter, and MMWF with RMSE, PSNR, CC, and UQI by applying the optimized mask size. As a result, the most improved RMSE, PSNR, CC, and UQI values were showed in MMWF algorithms.
