This study aims to define concepts on Hospital Design Focused on System to respond to the development and change by comparing general design methods of the General hospital architecture in Korea and analyze elements suitable to concepts on Hospital Design Focused on System in the General hospital architecture through examining the transformation of General hospitals in Korea. Essential architectural elements composing the Hospital Design Focused on System are as follows. First of all, the elements which can react to development of hospital architecture are HOSPITAL STREET and site situation. Secondly, core, equipment shaft, column, MAIN STREET and air handling unit room are elements of great importance as the location of these elements determines the dimensions and scale of the space which hospital functions are assigned to. Third, the area in regard to the rate of change is formed by MAIN STREET, which is the primary element, and envelope. The depth between MAIN STREET and envelope is defined as space depth. The flexible area is determined depending on this space depth and thus how to set up this flexible area determines the degree of readiness in responding to the change.

Chroma key technique which composes images by separating an object from its background in specific color has restrictions on color and space. Especially, unlike general chroma key technique, image composition for stereo 3D display requires natural image composition method in 3D space. The thesis attempted to compose images in 3D space using depth keying method which uses high resolution depth information. High resolution depth map was obtained through camera calibration between the DSLR and Kinect sensor. 3D mesh model was created by the high resolution depth information and mapped with RGB color value. Object was converted into point cloud type in 3D space after separating it from its background according to depth information. The image in which 3D virtual background and object are composed obtained and played stereo 3D images using a virtual camera.

Applying metric(distance) factor as weighting to spatial syntax is known to not contribute to the explanatory power for the human movement behavior as compared to the geometric(angle) factor according to the negative results of several related studies. However, Kim & Piao (2017) assumed that there is not a problem of the metric factor itself but a problem of the way of applying the metric factor as weighting, and presented a new possibility of the metric factor as weighting by proposing and verifying the methods of applying the metric weighting, which are different from the existing ones. The purpose of this study is to propose advanced methods of applying the metric weighting to space syntax, and to verify whether they contribute to the improvement of explanatory power of space syntax analysis. In this paper, we propose functions for combined depth of distance-step that combine the distance-weighted depth function with the step depth function and apply them to axial segment analysis to check the improvement of explanatory power of them.

The object of this study are 32 floor plans types of "Standard Korea Traditional-Houses Design=SKTHD.". The purpose of the research was to enhance the satisfaction level of users by comparing and analyzing the characteristics of the SKTHD. Research decision : 1. It tried to accommodate modern life by including space elements of modern housing, such as the 'entrance space', in the SKTHD. 2. The SKTHD. also favored the southern layout of living rooms and entrance spaces. 3.The number of bedrooms was generally planned to be two to three and it was judged that more various space and bedroom were needed to hold various functions of rural areas. 4. It has been analyzed that the depth of space is deeper to enter the entrance space(E)' than to enter from Thet-maru(TM). And as the depth of space in the Master bedroom is related to personal privacy, it is needed that the depth of space should be sufficiently.

The room temperature and air conditioning load in the underground space have been investigated numerically by the unsteady heat conduction equation. The model room has 3 m in height and 10 m in width, and it's position in the underground depth are 0.5 m to 5 m. When the room was located around surface, the room temperatures were strongly influenced by the atmosphere. But the underground depth is more than 2 m, the yearly temperature amplitude was small and the temperature phase was delayed. Up to 5 m of the depth, the cooling and heating load was decreased rapidly, but over 10 m of the depth, the air conditioning load was constant.

We proposed the method to present corrected depth cue to an observer by stereoscopic display. It was performed in sequence that designing the displayed space having a constant interval of depth and then defining the object space which had considered to an environment of display and based on computer graphics. Consequently, we had performed a different process of reported existing methods distinctively and taken the result which correctly designed depth cue having linearity whatever various sizes of display would be used.

Trap effects on the formation of space-charge field (SCF) associated with the photorefractivity of nonlinear optical polymers were studied by the Monte Carlo simulation using modified Gaussian disorder model. The charge transport dynamics influenced by the presence of trap molecules controls the formation of SCF via the charge distribution. Temporal behavior of SCF formation and SCF dependence on the trap depth are discussed in terms of the concentration and distribution of charges (holes and ionized acceptors) developed following illumination of light. The correlation of the trap depth and the energetic disorder is presented for an optimal efficiency for the SCF formation.

An experiment was conducted to observe the safranine penetration depth in radial directions of Populus tomentiglandulosa. Radial penetration was considered from bark to pith. In radial direction, ray parenchyma and intercellular space were considered for the measurement of safranine penetration depth. It was found that sapwood conducted safranine 24.23% higher in radial direction compared with heartwood. Intercellular space conducted safranine 39.27% higher depth compared with ray parenchyma and the penetration depth was 39.41% higher in sapwood compared to heartwood. During safranine penetration, it formed a curvature in the lumen of ray parenchyma. Initially safranine penetration was found high and decreased gradually.

Understanding the process of spatial perception plays a significant role in the design process as well as in the use of actual spaces. The perception of spatial depth can vary according to the space composition and design even there is no change in the actual size of the space. The properties of 3-dimensional space are its width, height, and depth; however, compared to the perception of spatial width and height, little research and theories exist on spatial depth perception. The reasons may be there less interest lies in the effect of spatial depth perception than that of spaciousness or height of space. This study is an investigation of the process of spatial depth perception using an eye-tracking device with stimuli developed through Computer Graphics. A total of 44 interior design major students participated in the eye tracking experiment; and they looked at three images comprised of an identical room with only changes in the rear wall condition. The results show that a significant difference in the fixation duration per stimulus exists. In addition, a significant difference exists on the fixation duration per stimulus according to the participants' answer of the deepest space. The result of this study can help identify factors for spatial depth perception, validate the assumption on it, and provide knowledge on how to acquire desirable spatial depth by utilizing the research result.

Backgrounds: Cervical epidural nerve block is useful in the management of a variety of acute, chronic and cancer related pain syndromes involving the head, face, neck and upper extrimity. To safely perfom the cervical epidural block, an appreciation of the expected distance from skin to epidural space is important. We studied the distance from skin to cervical epidural space of adults to determine if any relationship exists between patient height, weight and neck circumference and the distance from skin to epidural space. Methods: Patients 170, suffering from neck and upper extremity pain with cervical HIVD(herniated intervertebral dics) were selected. Cervical epidural block was performed at $C_{6\sim7}$ or $C_{7-}T_1$ intervertebral space. Then measured the distance from skin to epidural space and analysed the relationship between age, height, weight and neck circumference and the distance from skin to epidural space. Results: The cervical epidural depth of male $C_{6\sim7}$, male $C_{7-}T_1$, female $C_{6\sim7}$ and female $C_{7-}T_1$ groups were $5.17{\pm}0.63$, $5.47{\pm}0.59$, $4.84{\pm}0.56$ and $5.01{\pm}0.60$ cm respectively. Cervical epidural depth significantly correlated with body weight, ponderal index and neck circumference. Conclusions: The distance from skin to cervical epidural space has significant relationships with weight, ponderal index and neck circumference. Although experience is important, patient's weight and neck circumference are indicating factor, of the cervical epidural depth.
