The purpose of this study is to explore ways toward the hat design development by looking into the formative and aesthetic characteristics of the works of Philip Treacy, the designer who raised hats to one of the important fashion accessories. This study concretely investigates the formative characteristics of Treacy's hats in terms of shapes, materials, colours and decorations. According to this study, the shape of his hats shows the natural and specific objects in three dimensions, not in basic shape of hats. He uses combination of a variety of materials, adding unique materials to existing ones, so that they not only create a specific atmosphere but also extend the limitation which used to be thought as materials for hats. In the field of colour, he mainly used black and white until 1999, but since 2000 he has been using vivid and splendid colors. And he uses feathers or nets for decorations of the hats. As the result of the comprehensive analysis of Treacy's works, this study characterizes his works by surrealistic, three-dimensional, rhythmic and future-oriented. Therefore, Philip Treacy's hat design can be defined three dimensional considering the formative beauty, and can be characterized by use of unique materials, vivid & bold colours, moderate decorations, f variety of lines, and asymmetrical structures. These characteristics show surrealistic, three-dimensional and futuristic message which rhythm can be felt. He presents unlimited capability in hat designs as a representative of human being's basic will for creating new ones beyond this real world. It is considered that this study can help broaden the limitation of the hat design which used to repeat simple forms in the Past and help explore ways for developmental direction of hat design in the future.

Objective : The cerebrospinal fluid(CSF) pulsates within the craniospinal axis in response to rhythmic cerebral blood volume variation during the cardiac cycle. The aim of this study is to characterize the normal and abnormal CSF flow and its waveforms in the cervical spinal subarachnoid space. Methods : The magnetic resonance(MR) images were obtained with 1.5 T(GE Signa, GE Medical Systems, Milwaukee, USA) unit using the 2 dimensional cine PC(phase contrast) sequence with cardiac gating and gradient recalled echo imaging. This pulse sequence yielded 16 quantitative flow-encoded images per cardiac cycle. Sagittal and axial images of the cervical spinal CSF space were obtained, and target sites were analyzed for characteristic CSF flow (TR=50ms, TE=12.5-15ms). The region of interest(ROI) was 1mm 3 in volume. Twenty six persons were included in this study : 10 healthy volunteers and 16 patients with cervical myelopathy. The post-operative cine MR study were also done in five patients. Results : The normal CSF pulsation dynamics in the cervical spine showed discrete systolic and diastolic components. The CSF flow revealed a sine wave pattern, in which the systolic phase was shorter than the diastolic phase(ratio=2 : 3). The patient group revealed decreased amplitudes of the CSF flow and irregularly distored flow waves. The systolic phase was elongated in the ROI above the stenotic level, whereas the diastolic phase was lengthened below the level. In the postoperative images, the abnormal pattern and amplitude were found to be corrected. Conclusion : From these results, the authors believe that the CSF flow study provides valuable informations regarding the extent of cervical stenosis and may be useful for the surgical planning and post-operative evaluation.
