Through a investigation of the physical activity status of 1794 undergraduates who were non-sports majors from freshman to senior in Jiangxi Normal University, to analyze physical fitness status of college students with different physical activity levels. The results showed that in physical activity, high-intensity physical activity of male was higher than female, while medium-intensity and low-intensity (insufficient) physical activity of female was higher than male. College students' high-intensity physical activity group's physical test scores were better than the medium-intensity physical activity group, and the medium-intensity physical activity group was superior to the low physical activity group. In terms of physical fitness, among the test indicators of body shape and physiological function, the vital capacity and body mass index of male and female were ranked at a pass level. In the physical fitness test indicators, the performance of college students' endurance qualities was better while the overall performance of strength qualities was lower. The overall fitness of college students was ranked at a pass level, and the physical test scores of female were better than male.

This study was intended to research how such Japonisme affected the western fashion and to consider that the unique Japanese fashion was implemented in the western mode as the traditional aesthetic sense got jointed with the western culture together and was expressed as the modern Japonisme beauty. The beauty of 'Date' was the aesthetic sense created focused on the noble culture of public family. On the contrary, 'Iki', 'Wabi', 'Sabi' and 'Shibusa' is the Japanese lower middle class's universal living aesthetics. 'Kawaii' is influence on an animation, cartoon and character industry as well as the whole world’s fashion style as one of the common aesthetic sense of the world people in the modern time. That is, Japanese fashion designers expressed the human body with such the aesthetic sense by the design of shape, space, fusion, amusement through clothes. It could be concluded that they created an autonomous amusement’s design world over the visual beauty of human body.

Purpose: The purpose of this study was to investigate whether panoramic radiographs were useful in predicting osteoporosis. Materials and Methods: 50 postmenoposal women between the age of 41.8 and 78.5 were classified as normal and osteoporosis groups according to the bone mineral density of lumbar vertebrae. Panoramic radiographs were taken. Age, body mass index, remaining mandibular teeth, mandibular cortical thickness and morphology, and fractal dimensions at periapical areas of mandibular first molars were evaluated to differentiate the two groups. Results: The age of osteoporotic group was statistically significantly higher than that of normal group (p<0.05), but not the body mass index or number of remaining mandibular teeth. The mean fractal dimension of osteoporotic group was $1.391{\pm}0.085$, and was significantly lower than that of the normal group, which was $1.523{\pm}0.725$ (p<0.01). Thick mandibular cortical thickness was common in normal group, whereas thin or very thin mandibular cortical thickness was common in osteoporotic group and the difference was significant (p < 0.05). C2 pattern was common in normal group followed by C1, whereas C2 was common in osteoporotic group followed by C3. The difference was statistically significant (p< 0.0 1). Conclusion: Age, mandibular cortical thickness and shape, fractal dimension on panoramic radiographs were useful in predicting osteoporosis.

Objectives: The purpose of this study was to evaluate the change of body shape and the patient alignment state during image-guided volumetric modulated arc therapy in head and neck cancer patients, Materials and Methods: We performed a image-guided volumetric modulated arc therapy plan for 89 patients with head and neck cancer who underwent curative radiotherapy. Ten of them were evaluated for set up error. The landmarks of the ramus, chin, posterior neck, and clavicle were specified using ARIA software (Offline review), and the positional difference was analyzed. Results: The re-CT simulation therapy was performed in 60 men with $17{\pm}4$ cycles of treatment. The weight loss rate was $-6.47{\pm}3.5%$. 29 women performed re-CT simulation at $17{\pm}5$ cycles As a result, weight loss rate was $-5.73{\pm}2.7%$. The distance from skin to C1, C3, and C5 was measured, and both clavicle levels were observed to measure the skin shrinkage changes. The skin shrinkage standard deviations were C1 (${\pm}0.44cm$), C3 (${\pm}0.83cm$), and C5 (${\pm}1.35cm$), which is about 1 mm shrinkage per 0.5 kg reduction. Skin shrinkage according to the number of treatments was 1 ~ 4 fractions (no change), 5 ~ 13 fractions (-2 mm), 14 ~ 22 fractions (-4 mm) and 23 ~ 30 fractions (-6 mm). Conclusion: When the body shape changes about 5 mm, the central dose starts to differ about 3 % or more. Therefore, the CT simulation treatment for the adaptive therapy should be additionally performed. In addition, it is necessary to actively study the CT simulation therapy method and set up method of the lower neck and to examine the use of a new immobilization device.

Ancient Greece was a patriarchal society that distinguished gender roles between men and women. Although their costumes were composed of simple rectangular fabric without any technical complications in itself, the Greeks did try to express gender differences in their clothing. The final look of the Greek costume was dependent on the way the cloth draped onto its wearer as well as the wearer's identity. Greeks costume could just be seen as a rectangular fabric when it was not draped on a person's body. The purpose of this study is to examine how the gender differences were expressed in the ancient Greek drapery costume, which was made by using a completely different technical process, compared with the modern tailored costume. There are four elements of the costume that give the costume its formative shape, which are the wearer's body, the rectangular fabric (material as the first formative costume), the way the fabric is draped, and the final appearance as the second formative costume (the relationship between the wearer's body and the costume) and this study analyzes these elements individually. It is intended to analyze the gender characteristics and how each element appears in a different way from the perspective of Structuralism, an analytical method that considers a phenomenon as a total sum of the elements. Literature research was conducted and representative sculpture, painting and pottery, were used between the Archaic Period (B.C. 800~500) and the Classical Period (B.C. 500~323). The results show that the gender differences appear in each formative element of costume: First, the body was distinguished by the ancient Greek custom. The man's nudity was accepted while the woman's body was concealed. Second, in regards to the first formative costume, which was the rectangular fabric, men's were made with thick high quality wool because their involvement in outdoor activities meant that they needed clothes to stay warm, while the women wore clothes made of thin wool or hemp cloth, because their most of their activities were at home. Third, the way to drape the fabric shows the gender differences by changing the length of the clothing and its design ; men's short khiton was practical for big movement and at the same time the clothing exposed the man's body. The woman's doric khiton diversified its decoration by the size of the apotigma and by using the belt. Finally the second formative costume reflected the Greeks' social distinction between a man's body and a woman's body. The man's costume naturally exposed the man's body. On the other hand, the woman's long costume has a variety of shapes on the ground, that concealed her lower body, while the ornamental function was more accentuated than the man's costume. The gender differences expressed in Greek costume fundamentally reflected the point of view of the male and female body and their social roles in society.

The purpose of this study is to find out how important providing nutrition education to young students is. The study is based on the assumption that students' food behavior, nutrition knowledge and cognition of body image, weight control and nutrition education are considerably influenced by gender. A total of 495 students (249 boy and 246 girl students) were surveyed in one middle school located Siheungsi, Gyeonggido. The average height and weight of the boy and girl students are 164.6 cm, 54.4 kg and l58.5cm, 47kg, respectively. According to average BMI, the boy students($20.0kg/m^2$) are in the normal state. However, the girl students($18.2kg/m^2$) are underweight. For the status of meal intake, 52.4% of the students took breakfast everyday. Female students had dinner with lower intake frequency than males(p<0.05). For snack intake, the kinds of snack differ according to gender(p<0.05); more milk for male and more fruit for female students. The scores of dietary behavior based on Mini Dietary Assessment were 21.5/30 for male and 21.3/30 for female students. The nutrition knowledge scores of 4.6/10 for male and 4.6/10 for female students were not significantly different according to gender. The score of dietary behavior is based on Mini Dietary Assessment. The survey shows that in terms of the experience of weight control, 35.5% of the girl students have made an effort to watch their weight and 21.8% of the boy students have tried controlling their weight(p<0.0001). It turns out that the students who have been provided nutrition education are more satisfied with their body shape than those who have never been provided nutrition education(p<0.05).

Drag reduction of a running vehicle is very important issue for the energy savings and emission reduction of its power train. Especially for a solar powered electric vehicle, the drag reduction and weight lightening are two serious problems to be solved to extend its driving distance under the given energy condition. In this study, the ground effect of an airfoil shaped road vehicle was studied for an optimum body design of an ultra-light solar powered electric vehicle. Clark-Y airfoil type was adopted to the body shape of the model vehicle to reduce aerodynamic drag. From the study, it was found that the drag of the model vehicle was reduced as the height(h) between ground and the lower surface of the model vehicle was decreased. It is due to the reduction of the down-wash decreasing the induced drag of the vehicle. The lift was also decreased as the height decreased. It is due to the turbulent boundary layer developed beneath the vehicle body. The drag is classified into two types; the form and friction drag. The fraction of form drag to friction one is 76 to 24 on the model vehicle. As the height(h) of the model vehicle from the ground surface increases the form drag also increases but the friction drag is in reverse.

This study was conducted to examine the dietary behaviors with 510 high school students (260 males and 250 females) residing in Seoul. The average age of male and female students were 16.3 and 16.4 years old, respectively. Mean height and weight of male students were 174.1 cm and 65.9 kg and those of female students were 161.6 cm and 52.5 kg. The body mass index (BMI) of male and female students were $21.7\;kg/m^2$ and $20.1\;kg/m^2$, respectively, which were within the normal range. Students skipped breakfast more than once a week were 41.1% of males and 44.4% of females. More than 40% of the male and female students skipped breakfast frequently. The mean mini dietary assessment index score of male and female students were 30.6 and 29.6 out of total 50 index scores, respectively. Female students perceived significantly less healthy and fatter than male students. Furthermore, body image satisfaction of the female students was lower than that of male students. Female students were more significantly concerned with body image and desired a thin body shape. Only 22.7% of male students and 6.4% of female students exercised regularly, and the frequency, time, and intensity of exercise in the male students were significantly higher than those of female students.

An experimental study has been performed to study the effect of the base slant angle of a 1/10 scale two-dimensional vehicle-like body on its wake flow including the recirculating region, where the simplified shape of the body has been originated from a profile of a domestic passenger car. In the case of a Reynolds number based on the length of the model R=7.96*10$^{5}$ , the surface pressure coefficient, the mean velocity and the turbulent stresses have been measured, while the flow visualization technique using wool tuft has been adopted as well. When the base slant angle of the model is 15.deg., the free stream flowing parallel to the slant is observed to be separated from the lower edge of the slant, thus forming the smallest recirculating region. When the base slant angles are 30.deg. and 45.deg., the free streams are separated from the upper edge of the slant and the sizes of the recirculating zones are observed to be almost the same as when the base slant angle is 0.deg. From these observations, it is conjectured that between the base slant angles of 15.deg. and 30.deg. there exists a critical angle at which the size of the recirculating region becomes minimum and as the slant angle becomes larger than this critical angle the separation line moves along the slant towards the rear edge of the roof. Through the flow visualization technique, the existence of the two counter-rotating bubbles in the recirculating region has been clearly observed and verified.

The purpose of this research of this research was to survey the health of 181 male and 130 female students at K University in Chunganm from June 1 to June 23, 2001. It analyzed the students’dietary behaviors, life styles and perceived body shapes and the correlation of these factors to the health condition of the students surveyed. The results of the survey are summarized as follows. The average nutrition knowledge score (out of a possible 20 points), dietary attitudes score (out of a possible 50 points) and dietary habits score (out of a possible 30 points) were 8.66, 33.14 and 19.02 for males, and 9.99, 32.64, and 19.05 for females, respectively. The percentages of those who smoked, drank, smoked and drank and exercised regularly were 55.2, 92.8, 54.1, 82.9% for males, and 6.9, 91.5, 6.9, 63.1 for females, respectively. A significantly higher proportion of males smoked, drank, and exercised as compared to females (p<0.001). The percentages of students who were underweight, normal or overweight by BMI were 5.0, 79.0 and 16.0 for males, and 20.0, 78.5 and 1.5 for females, respectively. Fifty percent of females indicated that they felt they were obese, versus only 31.1% of males. Half of the females thought they were fattish, while only 31.1% of males thought that. Seventy-six point nine percent of females and 61.9% of males, more females than males, were dissatisfied with their weights. The health scores (the higher the point, the better the health condition) of the females (44.17) were significantly lower than those of the males (47.17) (p<0.001). A stepwise multiple regression analysis with health scores as the dependent variable and other scores as independent variables, indicated that the health scores of males were highly correlated with satisfaction with his body weight, smoking and drinking, and perceived body shape, whereas the females’health scores were highly correlated with obesity level, satisfaction with her body weight, and smoking and drinking.
