This study was conducted to compare body shape satisfaction, body image perception, weight control status, and dietary habits of Korean and Chinese female high school students in order to provide information for proper body image perception of adolescents. 221 students in Yongin, a city in Korea, and 227 students in Weihai, a city in China, were surveyed using questionnaires. Body shape satisfaction was significantly higher in Chinese students (P < 0.001) compared to Korean students. 76.2% of Korean students and 72.7% of Chinese students wanted a thinner body shape than their present body shapes. Experiences of weight control, laxative or diuretics uses, eating during weight control, and vomiting after eating were significantly higher in Korean students (P < 0.05-P < 0.001) compared to Chinese students. The score for dietary habits was significantly higher in Chinese students (P < 0.001) compared to Korean students, suggesting a more desirable dietary habit among Chinese students. Students of both countries showed a significantly positive correlation between body shape satisfaction and dietary habits, suggesting that as body shape satisfaction increases, dietary habits become more desirable. In conclusion, Korean female students showed a more distorted body image perception and had more poor dietary habits than Chinese students. Nutritional education for the establishment of normal body weight, proper body image perception, and healthy dietary habits are needed.

As a result of analyzing the floor plan shown in the three drafts, there were a great deal of differences in composing the space of the inner main hall. The inner room facing to the east with the arrangement crossing the inner floor at right angles in the 'Baekdangguje Draft' faces to the south in the east or west in front of the main house thereafter. This represents that it reflects the intent of the owner of the architecture emphasizing the size increase and ceremonies of the main house in the 'ㅁ shape', which has changed to the directions of easily accommodating the Confucian ceremonial activities in the floor plan of the inner house as the size of the main house was gradually increasing from 24 sections to 30 or 38 sections. The expansion in the size of main house further divided the functions of floor into one for daily life and the other for ceremonies as well. In other words, the 30 Sections in Yijeong Draft as being the first planned draft for reconstruction had a hall for memorial services in the main hall of the inner house, whereas the 'Draft with 38 Sections' as being the second planned draft for reconstruction was planning a room with a floor (two sections of Bangdang) for memorial purpose in the back of the inner main hall. The variations in the guest house (or space for men) shown in the drafts confirms the establishment of space for men as the size of the main house increases. We can see the change that a large guest house is placed over the south and in the south and east of the main house as the number of main house increases by 30 sections or 38 sections. Especially, a guest house with a wide space in a 'ㄴ shape' is arranged from the south of main house to the east wing in the Draft with 38 Sections. In addition, the backward sections are advanced in the front and back of guest house in the drafts with 30 and 38 sections, while a back floor or a back floor connecting to the back room or sleeping room or inner house is installed in the backward sections.

In the past, hospitals were planned with a minimum of public space for the sole purpose of treatment. On the other hand, modern hospitals have more public space as the importance of the healing environment increases and are planned taking into consideration the patients, guardians, and medical staff. In addition, the lobby shape is developed from a HALL type and planned as a STREET type or CONCOURSE type, increasing the public area. Unlike past hospitals, which were used as reception, waiting, and procedure spaces, modern hospitals are used as commercial, hobby, and cultural space. The purpose of the study was to evaluate the healing environment of the hospital lobby based on the shape of the plane surface by deducting the elements of general hospitals' healing environment from preceding studies as a framework. The hospital lobby is an important place where many actions occur. Therefore, 3 types of cases were evaluated based on the plane form. As a result of the study, the STREET type showed a better healing environment than the HALL type, but the accessibility, roof garden, and resting place showed similar results. Because the case was based on a large general hospital, which had sufficient planned space, the factor has little to do with the style of the lobby. Among the STREET types, the linear atrium showed a better result in terms of the sense of space and inflow effect of natural lighting than the four-sided atrium because the linear atrium has large open volume ratio. When the lobby plane is the HALL type, a cross section of the courtyard had a large open volume ratio. Therefore, the shape of the cross section is as important as the plane form of the lobby.

Recently, bridges have been momenttous as not only regarding function but also concerning aesthetics. However, when beauty is considered in the bridge, it is also essential that stability and economics be considered. Besides, when considering stability, an arch bridge is one of the most stable structures. The most important element is a rise ratio when regarding beauty and economics of arch bridges. The effect of dead load and DB24 load have been considered to decide proper rise ratio. Therefore, in this study, examined the value of moment, displacement and member forces, in the variation of the rise ratio of arch bridges. The most optimum shape of Nielsen arch bridges has determined by analyzing member forces, moments and displacement with parameters of rise ratio and angle of vertical members. By comparison between values, the hanger types have been also considered to derive the optimum shape of Nielsen arch bridge.

The purpose of this study is to investigate how five winning design proposals for the Seoul City Hall Plaza Design Competition have shown the spatial characteristics by comparing and reviewing them. Each design proposal shown different approaches that reveal the spatial characteristics. Through scrutinizing these design proposals, some similar and different aspects among them were identified. In order to examine these aspects, the winning design proposals were analysed and compared based on five categories such as design concepts, main facilities, representation of historical images, spatial connection, and event programs. Gilles Deleuze explained the spatial characteristics as striated space and smooth space. Striated space could be defined as sedentary space. It is distant vision-optical space that has dimensional, metric, and centered characteristics, whereas smooth space is defined as nomadic, close vision-haptic space that has directional and acentered characteristics. This study focused on the analysis of spatial characteristics according to smooth space and striated space. Based on the analysis of the spatial characteristics according to the smooth and striated space, some design proposals shown more characteristics of striated space while other proposals shown more characteristics of smooth space. Those design proposals that shown more characteristics of smooth space reveal flexible or changeable shape and void space, whereas the others that shown more characteristics of striated space try to suggest apparent guidelines for the future use by retaining the idea of a plaza through the concrete shape. This study, which analyzed the winning design proposals based on the spatial characteristics according to the smooth and striated space, can be used to analyze the designs and could help to develop a new methodology with a different perspective. furthermore, it could provide practical and creative design strategies for landscape design.

The dielectric barrier discharge (DBD) has low efficiency due to about 70% input power is consumed as thermal energy in the discharge space. However, because of the usage of DBD ozone generator is easier than other methods. The DBD ozone generator has been widely applied for high concentration ozone generation in the industrial application. But, the low-capacity compact DBD ozone generator is not applied so far. Therefore, the DBD ozone generator is necessary to improve ozone production efficiency and reduce the capacity. In this paper, the stainless steel pipe inner electrode was designed with hall type and screw type to improve the ozone production yield. The manufactured two inner electrodes were experimented with normal type for comparison of the discharge characteristics and the ozone generating characteristics. As the experimental results, the discharge current effective value of designed inner electrodes with hall type and screw type are higher than the normal type, due to unequal electric field is formed at the boundary. However, the difference of designed and original electrodes is less than 0.1mA that has no effect on the discharge characteristic. On the other hand, the screw type inner electrode increased higher than original model about 7 times when the flow rate of the oxygen source gas was increased from $0.6{\ell}/min$ to $1.0{\ell}/min$ The reason was assumed by the flow rate of the raw gas through the inner electrode was became fast that has a cooling effect. The designed hall type and screw type inner electrodes have shown good performances in ozone generation and ozone production that better than normal type in the same electrode surface area.

This study investigates the physical characteristics of indoor rest zones using the Space Syntax Method. A conceptual framework is based on analysis of design works presented in competitions(544 rest zones of 24 buildings on 7 campuses). The analysis on the unit type of rest zones showed that they were mostly available as open type, followed by semi-open type and outdoor rest places. On the other hand, by classifying the shape of whole building into traffic lines and nodal points, it was found that the buildings with 3 or more traffic lines have lower availability than others, because the buildings required more nodal points along a little higher complexity and zoning formed at increased nodal points between building masses. The analysis on the location of rest zones on traffic lines showed that hall type was most excellent in the level of availability. Finally, the analysis on the floor height showed that hall-like open rest places and outdoor places like rooftop garden functioned as a factor to enhance the integration of different spaces. In conclusion, this research will help the follow-up studies make spatial creation planning that may enhance the spatial efficiency and availability of Indoor rest zones on the campus.
