The analysis category of Art to Wear was text analyzed from the research material of 100 projects put together by fashion specialist. The conclusion of Art to Wear was comprehended the general features of it were compared and analyzed from a semiotics context. According to this analysis, the formative features of modern Art to Wear is categorized into three different dimensions from a semiotics light. The formative features of modem Art to Wear in the light of syntactic dimension was divided as an open constructed shape of Space Extension, non-typical Deformation, Geometrical Plasticity. The formative features of modem Art to Wear in the light of semantic dimension express symbolic meaning through metaphorical sign. These sign reflect the body image of the life and death and its objective of Abjection, Hybrid of discultural appearance and the image of Hyper-reality, which are features used to comprehend the inner meaning. The formative features of modem Art to Wear in the light of pragmatic dimension divided the artist emotion and meaning system delivered by Emotive Image, the Phatic Image that arouse inner signification and the Poetic Image which contain artistic and aesthetic meaning within it.

This paper presents a new method for roller design of IRB(isolation roller bearing) seismic isolation device using experimental evaluation. Three layered plate is adopted for the IRB in which the upper plate is placed on x direction and the lower plate is placed on y direction. The rollers placed in each plate make a plate movement. The roller is then optimally designed using variable geometric conditions. Stress distribution depends on the diameter and length of the roller and hence this is used for the determination of optimal geometry of the roller. In the experimental evaluation, it is observed that stress concentration at the end sides of roller is decreased and geometric coefficients depend on crowning dimension. In addition, in order to determine optimal design parameters of the roller the plastic deformation and friction are experimentally identified.

The multiple targets tracking problem has been one of the main issues in the radar applications area in the last decade. Besides the standard Kalman filtering, various methods including the variable dimen-sion filter, input estimation filter, interacting multiple model(IMM) filter, dederated variable dimension filter with input estimation, etc., have proposed to address the tracking and sensor fusion issues. In this pa- per, two existing tracking algorithm, i.e, the IMM filter and the variable dimension filter with input estima-tion(VDIE), are combined for the purpose of improving the tracking performance for maneuvering targets. To evaluate the tracking performance of the proposed algorithm, three typical maneuvering patterns, i.e., waver, pop-up, and high-diver motions, are defined and are applied to the modified IMM filter as well as the standard IMM filter. The smaller RMS tracking errors, in position and velocity, of the modified IMM filter than the standard IMM filter are demonstrated though computer simulations.

In this study, a novel method for dimension measurement of large-scale moving objects using stereo camera with 2-degree of freedom (2-DOF) mechanism is presented. The proposed method utilizes both the advantages of stereo vision technique and the enlarged visibility range of camera due to 2-DOF rotary mechanism in measuring large-scale moving objects. The measurement system employs a stereo camera combined with a 2-DOF rotary mechanism that allows capturing separate corners of the measured object. The measuring algorithm consists of two main stages. First, three-dimensional (3-D) positions of the corners of the measured object are determined based on stereo vision algorithms. Then, using the rotary angles of the 2-DOF mechanism the dimensions of the measured object are calculated via coordinate transformation. The proposed system can measure the dimensions of moving objects with relatively slow and steady speed. We showed that the proposed system guarantees high measuring accuracy with some experiments.

최근 GIS 시스템은 2차원에서 3차원으로 변환되고 있다. 3차원 GIS를 이용한 관련 분야가 급성장함에 따라 공공분야, 국방분야를 비롯한 일반산업에 이르기까지 점차적으로 다양화 되고 있다. 본 논문은 3차원 GIS기법으로 환경영향평가를 고려한 곡선부의 시거 안정성에 대한 분석가능성을 검토하였다. 시거는 입체성격을 지닌 도로 위를 입체성격의 운전자 시선과의 관계를 통해 결정하기 때문에 평면과 종단을 동시에 고려해야만 정확한 산정이 가능하다. 연구 결과 도로에 대한 설계속도 80km/h와 주행속도 60-120km/h까지 속도를 고려한 주행 시뮬레이션으로 시거 분석뿐만 아니라 기본적인 경관 주위 구조물 및 교량과의 조화, 안정성 평가뿐만 아니라 환경영향 평가가 가능할 것으로 보인다.

Purpose : We evaluated the fractal dimension changes on bovine rib radiographs according to the decalcification degree and the exposure time in the bovine rib. Materials and Methods : Twenty 5 mm thick cross-sectional blocks from bovine rib bone were progressively decalcified in 30 mL 0.1 N hydrochloric acid for 5, 30, and 90 minutes. They were radiographed at three exposure time settings (0.22, 0.36, 0.43 mAs) before and after each decalcification stage. We selected $100{\times}100$ pixel-sized regions of interests (ROIs) on trabecular bone and calculated fractal dimensions by box-counting method. Results : Repeated measures ANOVA showed that fractal dimensions gradually decreased after acid-induced demineralization and with more exposure (P<0.001). Conclusion : The fact that fractal dimensions decrease after decalcification might support the hypothesis that patients with osteoporosis have decreased radiographic fractal dimension in trabecular bone in comparison to normal subjects.

In this paper, I propose the effects of food therapy on subjects' health and happiness. The result has come out that food therapy enhances subjects' multi-dimensional health(medical, functional, self-evaluative) and their happiness. The participants were 230 adults over 30 years old living in Seoul and Gyeonggi district. To examine the effect of food therapy, the study sampled 220 questionnaire out of 230. By the non-equivalent control group design, the health levels were measured in three concepts: medical dimension, functional dimension and self-evaluative dimension. The results are as follows: First, participants who had taken food therapy for 3 months have been enhanced in their subjective and functional health level. Their subjective health enhanced from $2.80{\pm}.44$ to $4.07{\pm}.27$ (p=.000). And their functional health enhanced from $.92{\pm}.07$ to $.94{\pm}.07$(p=.035). Second, participants' happiness has enhanced significantly. Cognitive happiness enhanced from $3.39{\pm}.50$ to $3.84{\pm}.44$(p=.000). And emotional happiness enhanced from $2.76{\pm}.44$ to $3.07{\pm}.34$(p=.000). With this results, in case that people apply food therapy based on Yaksun, they are able to expect their enhancement of health level and happiness. Therefore study shows that Food therapy helps people to pursue their health and happiness improvement and suggest valuable information of a way to enhance quality of life.

The safety of a structure can be improved by applying the three dimensional passive earth pressure. Because the three dimensional passive earth pressure is much larger than the two dimensional passive earth pressure and it is determined by the size(width B and height H) and the wall frictional angle of the resistant wall. Therefore, the three dimensional passive resistance behavior was studied through the model tests in sandy ground, where the size of the resistant wall and the wall frictional angle were varied. The results show that three dimensional passive earth pressure is 1.1∼3.4 times larger than that of the two dimensional value depending on the wall size and the wall friction.

SPECT/CT는 SPECT의 기능학적 영상과 CT의 해부학적인 영상의 융합(Fusion)을 통하여 기존의 SPECT에서 병소의 위치 및 범위를 감별하는데 어려웠던 문제들을 해결하여 진단적 정보에 도움을 줄수 있다. Infinia Hawkeye 4 (GE Healthcare)의 SPECT/CT 감마카메라 영상과 진단용 CT영상을 융합(Fusion)하여 3D (three Dimension)로 Rendering 할 수 있는 Volumetrix Suite의 유용성을 소개하고자 한다. 본원에 SPECT/CT 검사를 하기 위해 내원한 환자 중, 동일한 검사부위의 진단용 CT영상이 있는 환자(Bone, Venography, Parathyroid, WBC)를 대상으로 Volumetrix Suite (Volumetrix IR, Volumetrix 3D)를 적용하였다. Infinia Hawkeye 4의 SPECT영상과 CT영상을 획득한 후 두 영상을 2D (two Dimension)로 융합(Fusion)하였다. Infinia Hawkeye4 SPECT/CT에서의 CT는 해부학적 정보에 한계가 있어, 3D (three Dimension) Rendering을 하기 위해서는 정보량이 많은 진단용 CT영상을 PACS상에서 DICOM (Digital Imaging and Communications in Medicine) File로 전송하여 Infinia Hawkeye4의 Xeleris Workstation에서 IR (Image Registration)한 후 Intergrating 3D (three Dimension)로 융합(Fusion)하여 2D(two Dimension)영상을 3D (three Dimension)영상으로 Rendering하였다. Volumetrix Suite program을 이용함으로써 Infinia Hawkeye 4의 SPECT/CT 영상과 별도로 촬영한 고해상도 진단용 CT영상을 3D Rendering하여 병소의 위치 및 범위를 감별하는데 좀 더 명확한 해부학적 정보를 얻을 수 있었다. 따라서, 해부학적인 정보가 부족한 핵의학영상을 보완함으로서 더 많은 정보를 제공해 핵의학영상 검사의 진단능력을 향상시킬 수 있을 것이라고 기대된다.
