After the "spatial turn" space narrative has become the hottest "doctrine". Howe er, the current space narrative to a bottleneck stage, a variety of reasons. "Spatial turn" of the modern trend of thought has a unshirkable responsibility. Has been, scholars turned to "empty" the complex relationship between space narrative and, type of narrative space narrative theory problem also not too clear by the noun, the term textual research, narrative of space studies provide some of the necessary theoretical support, to promote the healthy de elopment of the research on novel narrative space.

This study is intended to examine the various kinds of emptiness that are shown in the empty spaces created by Hyo-Sang Seung and Louis I. Kahn. Architecture creates the usefulness of a certain space thanks to its emptiness. The word, 'Emptiness' has the following meanings, 'non-fulfillment', 'non-existence', 'emptiness', 'blankness', 'non-visibility' and 'non-limitation', etc. Such concepts of emptiness can be broadly divided into 'ideological emptiness', 'aesthetic' and 'architectural spatial'. Comparisons regarding such concepts of emptiness as they are expressed in the architectural spaces created by Hyo-sang Seung and Louis I. Kahn shall be identified in this study. Hyo-sang Seung tried to leave numerous open possibilities which can contain everything into a certain space since 'emptiness' is not being used at this moment. Louis I. Kahn tried to contain into a space the essence and silence of that space before something that exists is created. The 'emptiness' created by Hyo-sang Seung and Louis I. Kahn is a specific space which can contain more kinds of non-visible spaces than some visible ones. Thus, such spaces may contain various potentials which are possible because they are empty, because of changes in nature and time, and because of silence and intentions going beyond an artist's original intent.

As shear-warp volume rendering is the fastest rendering method among the software based approaches, image quality is not good as that of other high-quality rendering methods. In this paper, we propose two methods to improve the image quality of shear-warp volume rendering without sacrificing computational efficiency. First, supersampling is performed in intermediate image space. We propose an efficient method to transform between volume and image coordinates at the arbitrary ratio. Second, we utilize pre-integrated rendering technique for shear-warp rendering. We propose new data structure called overlapped min-max map. Using this structure, empty space leaping can be performed so that we can maintain the rendering speed even though pre-integrated rendering is applied. Consequently, shear-warp rendering can generate high-qualify images comparable to those generated by the ray-casting without degrading speed.

Abandoned empty houses are largely left neglected as unused space, due to the slowdown in the real estate market that has resulted from the declination of urban functions. This research aims to analyze the characteristics of the City of Detroit's policies and regeneration efforts regarding abandoned houses, based on the perspective of unused space. This is expected to provide the baseline data for similar efforts to be applied to abandoned houses in the Korean context, thus preventing the decline of urbanism by adopting relevant policies and regeneration efforts. Some of the key features of the City of Detroit's regeneration efforts are: 1) the active participation of residents and open-data policies, 2) the diversification of regeneration strategies depending on the potential of the unused space, and 3) securing differential plurality of the regeneration processes.

LRU (Line Replacement Unit) modifications are often required for military aircraft due to aging. Recently, LRU modifications were proceeded for KA-O (Armed Airborne Controller) by replacing the ejection seat and adding avionic equipment, which made the aircraft's operational CG (Center of Gravity) on fuel consumption curve become out of the range of the specification requested. The off-ranged CG should be corrected by introducing an appropriate method. This study proposes a procedure for revising and verifying the empty weight CG altered due to LRU modification for small military aircraft (e.g., KA-O). In the proposed method, first, the change of empty weight CG of KA-O due to the LRU modifications is comprehensively examined. Then, several ballast masses are added to the engine mount strut to restore the empty weight CG on the fuel consumption curve to a safe operational range. The installations are verified via stress and fatigue analysis for various operating conditions. Considering that open information is not very available for the revision of empty weight CG, this study is valuable because it presents an established procedure for correcting and verifying empty weight CG during aircraft modification.

A new heuristic algorithm for the heterogeneous single container loading problem is proposed in this paper, This algorithm fills empty spaces with the homogeneous load-blocks of identically oriented boxes and splits residual space into three sub spaces starting with an empty container. An initial loading pattern is built by applying this approach recursively until all boxes are exhausted or no empty spaces are left. In order to generate alternative loading patterns, the load-blocks of pattern determining spaces are replaced with the alternatives that were generated on determining the load-blocks. An improvement algorithm compares these alternatives with the initial pattern to find improved one. Numerical experiments with 715 test cases show the good performance of this new algorithm, above all for problems with strongly heterogeneous boxes.

Peter Brook has been often referred to as the most important contemporary theater director in the West. The fact that he has directed many plays without being tied to a single theatrical theory occasionally makes people think he is a eclectic imitator. But when you carefully observe his work, you can understand that his openness is nothing else but the pursuit and examination of theatrical communication. In this context, Brook's idea reminds us of Bricolage. Bricolage has been widely known after the publication of "The Savage Minds". L$\acute{e}$vy-Strauss used the word to describe characteristic patterns of mythological thought in compared with modern scientific thought and regarded it as a system of thought that we need to restore. Director Peter Brook have sought effective ways to fill the empty space with his broad view of theatre and life. His consistent attempt reveals positive theatrical idea with the expansive possibilities of Bricolage thought.

In real time rendering of fetus the empty space leaping while traversing a ray is most frequently used accelerating technique. The main idea is to skip empty voxel samples which do not contribute the result image and it speeds up the rendering time by avoiding sampling data while traversing a ray in the empty region, saving a substantial number of interpolations. Calculating the distance from the nearest object boundary for every yokel can reduce the sampling operation. Among widely-well-known distance maps, those estimates the true distance, such as euclidean distance, takes a long time to compute because of the complicated floating-point operations, and others which uses approximated distance functions, such as city-block and chessboard, provides faster computation time but sampling error may can occur. In this paper, therefore, we analyze the characteristics of several distance maps and compare the number of samples and rendering time. And we aim to suggest the most appropriate distance map for rendering of fetus in ultrasound image.
