언리얼 엔진 기반의 메타버스나 실시간 게임 환경에서 캐릭터의 맞춤형 동작이 필요한 경우가 있다. 본 논문은 모션 디퓨전 모델을 활용하여 특정 동작을 자동 생성하는 기능을 제공하는 언리얼 엔진 플러그인을 제시한다. 특히 사용자가 텍스트로 신체 동작이나 감정 표현을 기술해 입력값으로 제공하면 서버에서 모션 디퓨전 모델로 애니메이션을 실시간으로 생성한 후, 언리얼엔진 클라이언트에서 후처리하여 사용자의 캐릭터에 실시간으로 적용하는 방식으로 구현했다.

The phase stability and the electrical properties of $La(Ni_{1-x}Cu_x)O_3$ (X=0.2, 0.4, 0.6, 0.8) have been investigated. The single phases were observed in the compositions of X=0.2, 0.4, and these single phases were stable up to $870^{\circ}C$ and $950^{\circ}C$ respectively. The electrical properties of these single phase samples showed metallic behavior similar to LaNiO3 from room temperature to the temperature at which the phase was stable.

Taylor series has a complicated structure comprising of various concepts in college major mathematics. This subject is a strong tool which has usefulness and applications not only in calculus, analysis, and complex analysis but also in physics, engineering etc., and other study. However, students have difficulties in understanding mathematical structure of Taylor series convergence correctly. In this study, after classifying students' mathematical characteristic into three categories, we use structural image of Taylor series convergence which associated with mathematical structure and operation acted on that structure. Thus, we try to analyze the understanding of Taylor series convergence and present the results of this study.

A statistical approach was carried out to analyze joint moments acting on the six subjects performing a right-handed seated task. The dynamic task analyzed consisted of moving a hand-held weight of lkg mass back and forth in front of a subject's chest at the shoulder level in an upright seated position. We used experimental data obtained in the Biomechanics Laboratory of the University of Michigan. Based on the acquired data from three trials by each subject, moments were calculated using a 3-dimensional biomechanical model at such articulations as wrist, elbow, shoulder, the third lumbar spine, hip, knee, and ankle joints. The linear correlation and the two way analysis of variance were applied to the calculated joint moments in order to investigate inter-subject and inter-trial varations. The results obtained showed that the largest magnitude and deviation of moment was found at the third lumbar spine, that any linear relationship could not be found between moment and its equivalents attempted in this study, and that the maximum value and deviation of moment acting on each joint were statistically the same for all three trials but those were statistically not the same for all six subjects.

The picosecond time resolved fluorescence spectra of Hematoporphyrin Derivative (HPD) in both solutions and cancer cell are measured by a time correlated single photon counting system with a synchronously mode locked dye laser. Two exoponential decay components in the fluorescence spectra were observed. The slow decay(6.3 ㎱)and the fast one(350 ㎰)are attributed to be originated from monomers and dimers, respectively. The absorption and fluorescence measurements in steady state also showed the presence of a monomeric and dimeric forms of HPD molecules. The monomer lifetime in the cancer cell was measured to be longer than that in solution, which was expected from the blue shift and narrowing of the absorption spectra for HPD-treated in vitro. The relative amplitude of the fast component was found to be enhanced in cancer cell, strongly indicating the higher affinity of the dimer for the cancer cell.

In this paper, we present a result of our study on how to construct a HIMCS(hospital image management and communication system) based on Windows system. The proposed HIMCS is composed of image acquisition units, image archiving and processing units, display units, and all units are interfaced with LAN. We construct high speed image transmission system for distributed database and retrieval of various medical pictures in ward through image transmission system and realize integrated image diagnosis. Hospital image management and communication systems(HIMCS) have been proposed as a way to meet the challenge presented by the growing volume of medical imaging data. These systems are based on the concept of handing images in digital form, there by marking use of advances in computer-based technology. A HIMCS offers a wide spectrum of advantages over filmbased imaging. Digital acquisition of images eliminates the need for film processing and associated costs in both time and materials.

This study describes the design of the biophysiological signal processing analyzer which can collect and analyze the biosignal raw data. System hardware is consisted of the IBM PC AT. pre-amplifier. AID converter, Counter/Timer. and RS-232C processor. Biophysiological signal data were processed by the software digital filter. FFT and graphic processing routine. The tachogram and FFT of the the peak to peak interval time was accomplished by the Graphic user interface software using the biophysiological signal processed data. Using this system. the powerspectrum of the heart rate variability during the long term could be observed. Experimental results of this system approach our purpose. which is improved the cost performance. easy to use. reducing raw-data noise and optimizing model for digital filter.

NMR spectroscopy enables us to measure the molar concentration of the metabolites in the organisms, and this technique is the only method to measure the concentration non-invasively. The proton NMR spectroscopy has been used to study the biochemical changes in human as well as in animal brain. MRI uses the proton densities and its relaxation times for reconstructing images, but MRS gives the biochemical changes inside the body. NMR spectroscopy could provide the information which MRI and CT could not, and this makes NMR spectroscopy more useful in diagnosing diseases. This study was tried to develop the quantitation of the molar concentration of the metabolites in the brain using the proton MR spectroscopy. The spectra of each metabolites was obtained, and the proton MR spectra was obtained from the insula gray matter areas of the 16 volunteers. And this spectra was analyzed to estimated the molar concentrations of the metabolites in the region. The results showed the very similar to those of the others.

The simulator which has a identical geometry with radiotherapy equipments, is a essential equipment to accomplish optimized radiotherapy plan through simulation by using diagnostic low energy X-ray. A Radiotherapy simulator has a combined technology from the therapeutic and diagnostic radiology and needs a periodical test for mechanical and optical properties, X-ray generator, image intensifier of simulator to keep the proper maintenance and radiation safety. Hence, tests were done and classified as i) mechanical and optical parameter for the gantry, collimator, and couch ii) key performance of the X-ray generator such as a kVp, mAs, and timer iii) performance of the image intensifier such as a resolution and contrast for three kinds of simulator, common use in clinic. The above result of tests will be applied to the acceptance test and periodical quality assurance procedure.

The aspirations toward newness and uniqueness, which are represented as the main character of modern society and the motivation of the Art, have made the media for the Art, Design and Image varied and developed. As one of those streams, laser technology has stood out for the visual media of mystery and fantasy in the field of Public Entertainment, Image Exhibition and Art, and also it could be accelerated by the advancement of Electronics and Physics. This study focuses on the image creation by the laser technology, as the great product of the state-of-the-art science, whose physical feature produces visual effect of fantasy. As the first approach, the knowledge on the physical feature and technology of laser and system composition should be preceded in the step of planning and creation of laser image. Through the further understanding on graphic feature of laser image which increases the artistic quality of the image, this study hopefully activates the laser image works by the specialists and the artists in the field, and finally the creation of master-pieces.
