Purpose: The purpose of this study was to determine the effects of the Traditional Play-centered Obesity Control Cooperative Learning Program based on the cooperative learning theory on obesity rate, physical fitness, self-esteem, and body image specifically in obese elementary school children. Methods: The research design for this study was based on a non- equivalent control group pretest-posttest design. The study was conducted from September, 5 to November 30, 2012. The subjects included 74 obese children ($Exp.=25^{(a)}$, $Com.=24^{(b)}$, $Cont.=25^{(c)}$) with an obesity rate above 20% at an elementary school in G City. Data analysis was performed using SPSS/WIN 18.0, using Chi-square test, one-way ANOVA, and Scheffe test. Results: The obesity rate (F=4.033, p<.022) in the experimental group was significantly lower than that in the group (Com, Cont), in which the Traditional Play-Centered Obesity Control Cooperative Learning Program was not implemented. Self-esteem (F=4.310, p<.017) also caused significant differences. However, physical fitness (Muscular endurance F=1.545, p=.220; Flexibility F=.671, p=.514; Agility F=1.594, p=.210; Speed F=5.386, p<.007, scheffe (a,b

Superparamagnetic maghemite nanoparticles were prepared by chemical co-precipitation, followed by a temperate oxidation stage, and investigated using FE-SEM, XRD, TGA, VSM, and M$\ddot{o}$ssbauer spectroscopy. Through SEM image and XRD analysis, its average particle size was found to be 13.9 nm. While VSM magnetic measurement showed typical superparamagnetic behavior at room temperature, M$\ddot{o}$ssbauer spectroscopic investigation revealed that non-vanishing magnetic hyperfine structure were retained. Cation distribution estimated from M$\ddot{o}$ssbauer spectroscopy confirmed the formation of maghemite nanophase in the sample.

The purpose of this study was to understand the influence of non-verbal communication of coffee shop employees on brand image and customer satisfaction. Based on a total of 317 samples obtained for empirical research, this study reviewed the reliability and fitness of the research model and verified a total of 3 hypotheses using the AMOS program. The hypothesized relationships in the model were simultaneously tested through the use of a structural equation model(SEM). The proposed model provided an adequate data fit, ${\chi}^2=434.380$ (p<0.001), df=178, CMIN/DF=2.440, GFI=0.886, AGFI=0.852, NFI=0.900, CFI=0.938, RMSEA=0.068. The model's fit, as indicated by these indexes, was deemed satisfactory, thus providing a good basis for testing the hypothesized paths. The SEM showed that kinesics(${\beta}=.311$), paralanguage(${\beta}=.242$), physical appearance(${\beta}=.382$) and proxemics(${\beta}=.481$) had a significant positive influence on brand image. In addition, brand image(${\beta}=.217$) had a significant positive influence on customer satisfaction. Furthermore, the effect of coffee shop employee non-verbal communication on customer satisfaction was found to be partially mediated by the brand image.

Chirimen (silk crepe) has been one of Japan's most distinctive textiles since times and has gained a reputation worldwide as the supreme example of Japanese costume. It is because of its distinctive quality and features, transcending the history, lacation and lacal of the people who wear this form of clothing, that chirimen has continued to highly valued over a long historical period. There is a wide range of literature on the subject of chirimen written from the standpoints of introducing the various types of material, discussing its history, and looking at the origins of the textile unions. However, most such writings are little more than fragmentary attempts to describe these matters from an empirical and publicity-oriented position. Very little serious research has ever been published in this area. In the present study I examine the features of chirimen. I began by directly interviewing kimono wholesalers, kimono stores and Western-style clothing stores on the subject of chirimen in order to establish a clear image of this fabric. I then went on to examine the subject experimentally in terms of the physical properties of the fabric in connection with the features of this image. In the study of the physical properties of the material, I selected habutae as a silk fabric to offer comparisons with chirimen. Habutae is used frequently together with chirimen in garments such as semi-formal visiting kimono (homongi), kimono in non-color fabric (ironashiji), mouming kimono (mofuku), broad-sleeved kimono (tomesode and furisode), and undergarments such ad juban.

In the relationship between post-modern feminism and the body. the body of women, which has been taken as 'other' by dominant arguments, has escaped from the fixed idea at post-modern times and the post-modern feminists tried to escape from the taste of the times about body image that was prevalent in the former times.'The taste of the times' here means the fixed physical form of ideal women's body by the educational custom, and it includes the educational prescription which establishes the docile body of women. This kind of educational custom aims at the perfect and permanent restriction on size, shape, desire, attitude and movement as well as on the overall demeanor and each part of the body. And the custom produces 'dependent and trained'. that is, inferiorized women's body. Hence, this paper points out that the feminity as a fixed Physical form should be overcome in order to move forward, and as one part of the effort, it attempts to analyze the designs which deformed and distorted women's body in 1990s. This research indicates that the work, which tries to deviate the fantasized and casted women's mystery, has been closely connected with the expression of 'non-separate bodies' and 'irregular body shapes' in 1990s, which aims at escaping from the fixation of women's body Image. Therefore, it is concluded that the target design trend of this research, which expressed the deformation and perversion of the body, provides the anti-these against the ideal body image of women and the these of feminity. which have been reproduced in various methods and patterns throughout the public and the culture on the whole by expressing the refusal and deviation of the existing women's body image through the post-fixation of the body pattern.

Caenorhabditis elegans (C. elegans) is an undulatory nematode which exhibits two distinct locomotion types of swimming and crawling. Although in its natural habitat C. elegans lives in a non-Newtonian fluidic environment, our current understanding has been limited to the behavior of C. elegans in a simple Newtonian fluid. Here, we present some experimental results on the penetrating behavior of C. elegans at the interface from liquid to solid environment. Once C. elegans, which otherwise swims freely in a liquid, makes a contact to the solid gel boundary, it begins to penetrate vertically to the surface by changing its stroke motion characterized by a stiffer body shape and a slow stroke frequency. The particle image velocimetry (PIV) analysis reveals the flow streamlines produced by the stroke of worm. For the worm that crawls on a solid surface, we utilize a technique of traction force microscopy (TFM) to find that the crawling nematode forms localized force islands along the body where makes direct contacts to the gel surface.

Since the development of Bubble Image Velocimetry (BIV) technique as the complementary technique of Particle Image Velocimetry (PIV), the application of digital imaging technique in the field of hydraulic and coastal engineering increased rapidly. BIV works very well in multi-phase flow (air-water) flows where the PIV technique doesn't. However, the velocity field obtained from BIV technique often resulted in a velocity vector on the outside of the flow (false velocity) since the Field of View (FOV) usually not only cover the air-water flow but also the area outside the flow. In this study, a simple technique of post processing velocity field was developed. This technique works based on the average of the pixel value in the interrogation area. An image of multi-phase flow of wave overtopping was obtained through physical experiment using BIV technique. The velocity calculation was performed based on the similar method in PIV. A velocity masking technique developed in this study then applied to remove the false velocity vector. Result from non-masking, manually removed and auto removed false velocity vector were presented. The masking technique show a similar result as manually removed velocity vector. This method could apply in a large number of velocity field which is could increase the velocity map post-processing time.

We evaluated the effect of low power GaAsAl laser on re-epithelization in full-thickness excisional wound of rat skin. Two full-thickness excisions were made on the back of the experimental animals. Low power laser applications with 10mW intensity were treated experimental animals twice a day for 7 days. On the seventh postoperative day the quantitative analysis of re-epithelization was performed using immunohistochemical staining for proliferating cell nuclear antigen (PCNA). The majority of PCNA immunoreactive cells was observed at epithelial cells in the margin of full thickness excisional wound. The low power laser treatments significantly increased the number of PCNA immunoreactive cell as compared to that of non treated animal group (p<0.01). The shape of PCNA immunoreactive cell appeared as small dark, round to ovoid structures. Most PCNA immunoreactive cells exhibited a high intensity of staining that contrasted sharply with the surrounding background. In conclusion, these findings suggest that GaAlAs laser treatments effectively enhance the epithelial wound healing by the stimulating cell proliferation. Furthermore, the majority of cell proliferation occurred in the margin of full thickness excisional wound.

Purpose: This study aimed to investigate the relationship between forward head posture and pulmonary function in young women. Methods: Thirty-three young women participated in this study. The participants were grouped into non-forward head posture, mild forward head posture, and moderate-severe forward head posture groups. The craniovertebral angle (CVA) and pulmonary function were measured using ImageJ and a spirometer, respectively. Results: Statistically significant differences in the participants' forced expiratory volume for one second (FEV1) and predicted forced expiratory volume for one second (predicted FEV1) were found among the three groups. No statistically significant differences in the participants' forced vital capacity (FVC), predicted forced vital capacity (predicted FVC), FEV1/FVC, and peak expiratory flow (PEF) were found among the three groups. Furthermore, a significant positive correlation was found between CVA and FVC and among the predicted FVC, FEV1, and predicted FEV1. Conclusions: The results of this study demonstrate that severe forward head posture has a negative effect on pulmonary function in young women.

It was diagnosed customer transformers and other equipment by using non-contact infrared equipment. Examiners can identify not only abnormalities in real time in the field of the transformer immediately, as well as they were able to safely perform the scan. Thanks to successful transformer diagnosis, we can easily diagnose abnormalities of transformer itself which can be caused by deterioration of the oil used as overlaod or refrigerant and we can also diagnose abnomalities from low voltage bushing which can be result by external environmental factors and physical factors and abnomalities from its connections at the same time we found it is very useful at proactive diagnostics.
