  • This study is as skyscrapers are becoming increasingly taller, more constructors have decided the height alone cannot be a sufficient differentiator. As a result, atypical architecture is emerging as a new competitive factor. Also, it can be used for symbolizing the economic competitiveness of a country, city, or business through its form. Before the introduction of digital media, there was a discrepancy between the structure and form of a building and correcting this discrepancy required a separate structural medium. Since the late 1980s, however, digitally-based atypical form development began to be used experimentally, and, until the 2000s, it was used mostly for super-tall skyscrapers for offices or for industrial chimneys and communication towers. Since the 2000s, many global brand hotels and commercial and residential buildings have been built as super-tall skyscrapers, which shows the recent trend in architecture that is moving beyond the traditional limits. Complex atypical structure is formed and the formative characteristics of diagonal lines and curved surfaces, which are characteristics of atypical architecture, are created digitally. Therefore, it's goal is necessary to identify a new relationship between the structure and forms. According to the data of Council on Tall Buildings and Urban Habitat (CTBUH), 100-story and taller buildings were classified into typical, diagonal, curved, and segment types in order to define formative shapes of super-tall skyscrapers and provide a ground of the design process related to the initial formation of the concept. The purpose of this study was to identify the correlation between different forms for building atypical architectural shapes that are complex and diverse. The study results are presented as follows: Firstly, complex function follows convergence form characteristics. Secondly, fold has inside of architecture with repeat. Thirdly, as curve style which has pure twist, helix twist, and spiral twist. The findings in this study can be used as basic data for classifying and predicting trends of the future super-tall skyscrapers.

  • The hypothetical protein TTC0263 of Thermus thermophilus HB27 is a thermophilic tetratricopeptide repeat (TPR)-containing protein. In the present study, the TPR region (residues 26-230) was resolved at $2.5{\AA}$ with R-factors of $R/R_{free}$ = 23.6%/28.6% $R/R_{free}=23.6%/28.6%$. TTC0263 consists of 11 helices that form five TPR units. Uniquely, it contains one atypical "extended" TPR (eTPR) unit. This comprises extended helical residues near the loop region of TTC0263, such that the helical length of eTPR is longer than that of the canonical TPR sequence. In addition, the hybrid TPR domain of TTC0263 possesses oligomer-forming characteristics. TPR domains are generally involved in forming multi-subunit complexes by interacting with each other or with other subunit proteins. The dynamic structure of TTC0263 described here goes some way to explaining how TPR domains mediate the formation of multi-subunit complexes.

  • The purpose of this study was to investigate developmental trends in organization strategy for taxonomic and slot-fiber lists and category typicality, use of organization strategy in relation to developmental changes in category knowledge structure, emergent organization capacity and effects in category typicality on children's recall. Moreover, the influences of children's age, use of organization strategy, list types and category typicality on children's recap were figured out. The major results were as follows. 1. Children's recall use of organization strategy increased with age. That is, the older children performed better recap and used organization strategy on both list types than the younger children. 2. AU children performed recall and used organization strategy better for the slot-filler than taxonomic list. The 4-year-olds, however, demonstrated better recap and use of organization strategy for the slot-filler than taxonomic list. While the 6-year-olds and 8-year-olds showed no such differences. These findings were supported the view that script-based slot-filler categories have a strong influence on young children's memory performance. 3. At each age level, children showed higher level of recall and use of organization strategy for category typical than category atypical list. AU children received higher scores for the typical than atypical items on recap and use of organization strategy. 4. Children's age, use of organization strategy, list types, and category typicality of lists significantly predicted children's recap.58% of the variance of children's recap was explained by four variables.

  • In this study, structural characteristics were analyzed by combining gravity load and lateral loads such as seismic loads through static analysis of example structures, and the static characteristics of the twisted structure according to the plane rotation angle were also analyzed. Example structures were selected as regular structure, and twisted structures; 1.0, 2.0, and 3.0 degree angle of rotation per story, and static analysis was performed by the load combination case 1 and case 2. As a result the story drift ratio of the twisted-shaped structure also increased as the plane rotation angle per story increased. The eccentricity according to the load combination was the highest in the lower stories of all analysis models, and the eccentricity was found to be larger as the rotation angle decreased. The twisted-shaped structure was more responsible for the bending moment of the column than the regular structure, and the vertical member axial force of all analysis models was almost similar.

  • The goal of this research is to find the difference between F. Gehry's museum architecture's extremely abstract and chaotic space composition and that of other architect's. Gehry's four museum architectures built from late 1980s to 2000 were selected for analysis. Four more museums, built in the same era with the size of that (atypical) museums, were selected for comparative studies. Space Syntax, a quantitative analysis method for spatial configuration, is used to find the characteristics of internal spaces. The Result shows that Gehry's museum architectures' connectivity is 0.375 times bigger and integration is 0.731 times smaller than the compared museums. High connectivity suggests that their visitors could take diverse routes. Low integration implies that their routes are less efficient than the compared museums overall. Their intelligibility is slightly higher than the other museums. This means their visitors have comparatively high understanding of the internal space.

  • Primary non-Hodgkin's lymphoma of the lung is rare among extranodal lymphomas. The most common form is low grade B-cell type originated from the mucosa-associated lymphoid tissue (MALT) of the lung and primary peripheral T cell lymphoma of the lung is extremely rare. We recently experienced a case of fine needle aspiration cytology of primary peripheral T cell lymphoma of the lung in a 39-year-old male patient. The cytologic smears revealed some sheets of reactive epithelial cells, epithelioid histiocytes, and numerous polymorphous population of lymphoid cells composed of small and intermediate sized lymphoid cells and mature lymphocytes. Lymphoid cells were slightly larger than normal mature lymphocytes and showed significant irregularity of nuclear membrane. The internal nuclear structure was marked by chromatin clumping, clear parachromatin areas, and inconspicuous nucleoli. Histopathologically, atypical small lymphocytes infiltrated in the interstitium and alveolar sac. By the immunohistochemical study and molecular biologic study of gene rearrangement, the T cell clonality of atypical lymphoid cells was confirmed.

  • Purpose: Tragus is one of the key structure of the normal shape of auricle. We experienced several cases of hypoplastic tragus with preauricular appendage. This article describes the methods of reconstruction of atypical tragus using accessory tragus or macrotragus to make better aesthetic results rather than simple excision. Methods: From April, 2004 to March, 2009, 21 patients got operations by our method. Seven patients had bilateral deformity of tragus. Mean age was 12.7 years. For 17 cases of accessory tragus, simple excision, z-plasty and interpolation flap was performed. For 11 cases of macrotragus, debulking and z-plasty was performed. Mean follow-up period was 9.4 months. Results: Reconstructed tragus looked symmetric with the opposite side in contour, size, direction and partial coverage of auditory meatus. There was no enlargement of remnant appendage for the follow up period and there was no complication such as hematoma, infection and chondritis. Conclusion: In cases of small and deformed tragus, preauricular tissue such as accessory tragus and macrotragus could be a good source of tragal reconstruction.

  • One way to shield an atypical structure to secure the occupant safety of an impact vehicle is to stack energy absorbing material modules around the structure. To be applicable to a cushion module, material must have enough energy absorbing capabilities while satisfying the safety requirements of the vehicle occupant. Static compression test of the potential materials gives a good indication which material is good for a slacking module. This paper presents the mechanical properties that a cushion material must have to satisfy the safety requirements. Static tests are performed for Quard-Guard system module, sand bag, recycled tires, Geo-Container, Geo-Cell and Expanded Polystyren (EPS) Blocks. Static test results are discussed and EPS block of $30kg/m^{3}$ density showed good potential for a cushion module. To check the dynamic effect of EPS block, drop tests have been made up to 35.6km/h impact speed. Drop test results are compared with static test results and no appreciable difference was found. To improve the EPS module property, making holes to the block is suggested and drop test are performed for the modified blocks. From the drop test results, design values are suggested.
