정보통신기술의 빠른 발전과 디지털콘텐츠 산업의 확대로 인해 관련 실용학문분야는 교육의 내용과 환경에서 새로운 패러다임이 요구되고 있다. 특히, 디지털콘텐츠 산업의 핵심 분야인 애니메이션 교육은 창의와 융합 그리고 실무교육이 중시되며 교육 내용과 방법에서 많은 개선이 시도되었다. 하지만, 기존 컴퓨터실 형태의 획일적 교육 공간은 애니메이션 교육특성을 충분히 반영하지 못하고 있는 실정이다. 이에, 본 연구는 애니메이션 분야 직무 역량과 애니메이션 프로젝트 제작의 특성이 반영된 효율적인 실습교육 공간 구성을 제안하고자 한다. 이를 위한 연구의 전개는 첫째, 기존의 애니메이션 교육공간의 한계점에 대해 사례를 통해 분석하고, 그 문제점을 도출한다. 또한, Pre-production, Main-production, Post-production의 세 단계로 구성된 애니메이션 제작의 작업적 특성과 순차적 업무에 따른 여섯 개 세부 직무의 역량에 대해 고찰한다. 둘째, 애니메이션 제작공간의 구성을 파악하기 위해 공간구문론을 차용한 6가지 공간 유형에 대해 고찰한다. 셋째, 애니메이션 제작특성, 세부직무역량 요소, 6가지 공간 유형을 분석 툴로 하여, 애니메이션 제작 스튜디오인 Walt Disney의 작업환경과 공간구성에 대해 사례분석을 진행한다. 다섯째, 문헌연구와 사례연구의 결과를 연계적으로 분석하여 애니메이션 프로젝트 진행을 위한 효과적인 교육 공간 구성의 특성을 도출한다. 본 연구를 통해 프로젝트 실무와 직무역량요소의 특성이 반영된 교육 공간 구성을 제시하는데 의의가 있으리라 사료된다. 또한, 본 사례분석을 통해 애니메이션 교육공간 구성을 일반화 하는데 한계가 있으나, 기존과 차별화된 프로젝트 교육 공간구성을 위한 참고자료로 활용가치가 있으리라 기대한다.

Capillary tube 10개를 $^{99m}Tc$로 채워서 고정식-초점형 SPECT와 회전식-평형 SPECT 장비를 이용하여 선예도와 감도를 평가하였다. 그리고 이 데이터를 이용하여 검출-조사야 내에서의 평균값과 표준편차를 이용하여 균일도를 나타내는 변동계수를 평가하였다. 고정식-초점형 SPECT의 선예도 균일도와 감도 균일도는 회전식-평형 SPECT 에 비해 각각 68%, 110% 높게 평가되었다.

We briefly introduce the theory of GB-SAR focusing and interferometry. Deramp-FFT algorithm is evaluated as a far-range, partial focusing method along with its limitations in the near-range application. Various interferometric configurations with temporal, spatial, and/or frequency baselines are also discussed.

A novel hyperspectral imaging spectrometer controlling spatial and spectral resolution individually has been proposed. This imaging spectrometer uses a zoom lens as a telescope and a focusing element. It can change the spatial resolution fixing the spectral resolution or the spectral resolution fixing the spatial resolution. Here, we report the concept of the hyperspectral imaging spectrometer with the novel zooming function and the optical design of a zoom lens as the focusing element. By using lens module and third-order aberration theory, we have presented the initial design of four-group zoom lens with external entrance pupil. And the optimized zoom lens with a focal length of 50 to 150 mm is obtained from the initial design by the optical design software. As a result, the designed zoom lens shows satisfactory performances in wavelength range of 450 to 900 nm as a focusing element in an imaging spectrometer. Furthermore, the collimator lens of the imaging spectrometer is designed through the third-order aberration correction by using an iterative process.

Using a spatial compound imaging technique in a medical ultrasound imaging system, the average speed of sound in a medium of interest is measured, and imaging of its distribution is implemented. When the brightness reaches the highest level in an ultrasonic image obtained as the speed of sound used in focusing is varied, it turns out that the focusing has been accomplished satisfactorily and that the speed of sound which has been adopted becomes the sought-after average speed of sound. Because spatial compound imaging provides many different views of the same object, the adverse effect of erroneous speed-of-sound estimation tends to be more severe in compound imaging than in plain B-mode imaging. Thus, in compound imaging, the average speed of sound even in the case of speckled images can be accurately estimated by observing the brightness change due to different speeds of sound employed. Using this new method that offers spatial diversity, we can construct an image of the speed of sound distribution in a phantom embedded with a 10-mm diameter plastic cylinder whose speed of sound is different from that of the background. The speed of sound in the cylinder is found to be different from that of the surrounding medium.

A structural health monitoring (SHM) technique for locating impact position in a composite plate is presented in this paper. The technique employs a single sensor and spatial focusing properties of time reversal (TR) and inverse filtering (IF). We first examine the focusing effect of back-propagated signal at the impact position and its surroundings through simulation. Impact experiments are then carried out and the localization images are found using the TR and IF signal processing, respectively. Both techniques provide accurate impact location results. Compared to existing techniques for locating impact or acoustic emission source, the proposed methods have the benefits of using a single sensor and not requiring knowledge of material properties and geometry of structures. Furthermore, it does not depend on a particular mode of dispersive Lamb waves that is frequently used in the SHM of plate-like structures.

The purpose of this study was to identify the conditions of neighborhood facilities for the elderly, paying special attention to the accelerated aging phenomenon in rural areas of Korea. We contrived a new index to measure spatial accessibility for people aged over 65 years, and we analyzed spatial accessibility by focusing on community facilities: public bath facilities, beauty shops, rural public facilities, markets, big stores, and large-scale retail shops. The most outstanding spatial accessibility among community facilities was found with the rural public facilities thanks to governmental installing adequate facilities in the past, followed by the beauty shops and the public bath facilities. In contrast, spatial accessibility of the markets was in the lowest. Spatial accessibility of community facilities for the elderly exhibited high variability among the rural areas. We confirmed significant inequality of spatial accessibility in all facilities we studied. The areas that had better spatial accessibility diverse combinations of the facilities. The areas that had worse spatial accessibility were, on the whole, consistent with traditional undeveloped regions. In the near future rational planning of facilities will be needed to supply adequate accessibility in targeted areas which currently had low accessibility. In order to improve the spatial accessibility of neighborhood facilities, the most essential factor is to take into account the geographical distribution patterns of rural settlements.

University is very big scale among urban facilities as for single facilities and there is characteristic that accompany various university support functions in contiguity area. Width that have diverse spatial configuration generally our country university campus around was formed, this does function that connect university and ambit. Specially, formation enables change of spatial configuration that existent width system has if is new around university campus. Also, can form more animate and lively width spatial configuration by forming more various and complex width spatial configuration in width had formed in existing. It is that search special quality of university surrounding width spatial configuration analyzing existing width spatial configuration of Kangwon National University back gate by formation if this study is new in city and forecasts the change, and used space syntax by spatial configuration analysis method.
