Background: This study was designed to determine the distance from skin to lumbar epidural space in obstetric parturients and whether weight, height, or PI (ponderal index, $kg/m^2$) might influence the epidural depth. Methods: 71 obstetric patients undergoing elective cesarean section during epidural anesthesia in L2-3 level were partitioned into groups according to their prepregnant BMI(body mass index), and in each group weight, height, PI, epidural depth were measured. Results: All patients were classified as underweight(n=18), normal(n=49), overweight(n=4) and no one was partitioned into obese group. the distance from skin to lumbar epidural space was found to be 3.7 cm(underweight), 4.1 cm(normal), 4.7 cm(over weight) and total mean distance was found to be 4.0 cm. The epidural depth had correlation with weight and height in underweight, and weight and PI in normal, but had no correlation with any measurements in overweight group. Conclusion: These results suggest body weight may be a useful parameter for predicting the distance from skin to lumbar epidural space in underweight and normal weight obstetric parturients.

This research regards that experiencing certain space according to looking through sensations of body will finally make visual perceptional experience to happen. Our bodies incorporate sensible experience along with interactions with surrounding environment while making movements. The analysis of Seongyojang in Gangleung through top and bottom, depth, movement and experience space which are Merleau Ponty's phenomenological space elements has led to the following conclusions. First, the up and down directivity inherent in Seongyojang has different directions in movements by the axis of plane. Second, the depth by the correlation between things and bodies shows the interactions with things and the depth of space rendered by the servants' quarters of '一字形' and the overlapping effect from the movement between buildings can be seen and felt. Third, mobility is focused on the surroundings for the movements of body and thing. Fourth, the experienced space remains as what it is and is experienced through the experience of traditional cultures. The temporality where the past and the present subsist is given with the application of the modern living pattern in the traditional space. That is, the space from the point of phenomenological view makes the visual-perceptual experience possible through the senses of body, with which the space is experienced and sensed. In other words, the space from the phenomenological viewpoint makes visual-perceptual experience possible through the senses of body so that the space may be experienced and perceived. Through this study, a new viewpoint toward Korean traditional space is expected to be discovered.

This study aims to find out the characteristics and the type classification of contemporary public libraries in terms of browsing circuit. In so doing, it is to analyze 21 recently built libraries by using the browsing circuit, the spatial depth and the spatial layout. The study makes use of codes derived from the concept of 'Classification' and 'Frame' suggested by a pedagogist, Basil Bernstein. As a result, it shows that two codes are phased in overseas cases. In other words, one type is a lower depth of space and a high rate of rings with the multi-layer circuits and the three-dimensional circuit of multi-centered. the other type is the higher depth of space and a low rate of rings with the single-layer circuit and the multi-layer circuit of single-centered. In domestic cases, 4 types are shown. The characteristics of layout are seen as a radial shape and the rate of rings is lower than the overseas cases. It can be said that these results are a transitional phenomenon. For browsing circuit, domestic public libraries would be adapted to the three-dimensional circuit of multi-centered, a lower depth of space and a high rate of rings. By instructions of this plan, the real meaning of a public library will be come true.

Though a variety of demands for an green dwelling, it is hard to diffuse a wooden house due to high construction cost. So this study aims to diffuse to propose a space modular for production and supply. Therefore the result of investigation to the space modular of each room through the survey of width and depth in the type of dwelling in korea is as follows. 1) Investigated the mixture of magnitude on the total width and depth, the survey is showed commonly 3.6m and 4.2m. 2) Once the depth is 3.6m, a living room and inner room, room's width is 3.9m, 4.5m. Once the depth is 4.2m, those width is 4.8m. 3) By use of a survey, the post distances consisted of all rooms are 3.6m, 3.9m, 4.2m, 4.5m, 4.8m. The result of investigation to possibility for mixture applied to six level types invested post modules to the wooden house of post & Beam method is as follows. 1) With the regularity of depth and simplicity of width, It is potential to compound floor plan in korea. 2) It is possible to plan an informal shape of kitchen+dining room which is a spare space available for the merit changeable space after arranged main rooms. 3) It is possible to plan a space through a variety of mixture method at bathroom. Thus, it is possible for a variety of floor formations to build a low-cost wooden house through five types of post distance.

Today's young generation users are very active in expressing themselves through smart phones, form networks in this cyber space and express their identities freely. Therefore, this study aims to investigate how young people in their 20s are expressing themselves through smart phones and the differences from the attempt of self-expression in the existing cyber space. The research method was an in-depth interview, which was a qualitative research method, aimed at people in their 20s, so that they could freely talk about their thoughts and feelings. In-depth interviews are useful for users' psychological and in-depth analysis of behavior.

The apparent depth of space charge region on the ZnO $(10{\bar{1}}0)$ surface in chemisorption of oxygen has been estimated from the capacitance of two contacting faces. When the sample (donor concentration: $2.4{\times}10^{22}\;m^{-3}$) was evacuated at 773 K for 1 hr the depth reached to 40-100 ${\AA}$ depending on sample assembly. Admission of oxygen to the sample resulted in an increase of the depth to 3600 ${\AA}$ where the increment was greater at higher oxygen pressure between 6.6-1600 $N/m^2$. Admission of CO to the sample previously exposed to oxygen yields a decrease in the depth. The results of the measurement support that oxygen is adsorbed as an acceptor on ZnO $(10{\bar{1}}0)$.

In this paper, we present an upsampling technique for depth map image using color and depth weights. First, we construct a high-resolution image using the bilinear interpolation technique. Next, we detect a common edge region using RGB color space, HSV color space, and depth image. If an interpolated pixel belongs to the common edge region, we calculate weighting values of color and depth in $3{\times}3$ neighboring pixels and compute the cost value to determine the boundary pixel value. Finally, the pixel value having minimum cost is determined as the pixel value of the high-resolution depth image. Simulation results show that the proposed algorithm achieves good performance in terns of PSNR comparison and subjective visual quality.

Due to the fact that there are low birth rate and longer life longevity, schools have been shutting down and converted into welfare facilities. However, most of researches about utilizing closed down school are focused on case researches or architectural planning and design. Moreover, majority of existing welfare centers for the aged are not designed with the flow of human traffic in mind, which means there is no consideration of physical or psychological characteristics of elderly people. That fact leads to increasing number of shutting down welfare facilities. Therefore, this thesis will present the necessity of effective space allocation, extension and reconstruction for residents in aged care by analyzing space using index of space syntax with depth-map software.

The café has become an important representative "third place" where people study and rest. Hence, it is worthwhile for researchers to understand the needs of individual users as well as the requirements of people who visit such venues in groups. The identification of strategies that can help achieve larger, wider, higher, or deeper interior spaces in small and compact locations can generate benefits for both users and designers. In this study, where 56 interior design students participated, we used an eye-tracker and images of cafes to explore the relationships between spatial depth and the intention to visit a cafe space. The researchers digitally developed fifteen different conditions of space and measured the eye movements of the participants using an eye-tracker when they examined images that appeared to convey the most depth. Participants were also asked to imagine the proposed space images as cafes and to select one of the 15 images as the location that they would be most likely to visit individually and one that they would frequent in the company of other people. The research results revealed that certain ways of using interior design elements altered the participants' perceptions of spatial depth without any change being effected to the actual volume or the size of the space. The participants tended to perceive a space with a small decorative artwork on a dark toned wall with unconnected furniture as deeper than a space with no or large artwork on a light toned wall with contiguous furniture. Spatial depth was a more important consideration for an individual visit than for a group visit. The results of this exploratory study will help scholarly understanding of the role played by spatial depth in customer intentions to visit a cafe.
