본 논문은 3D 스캐너 및 센서 등으로 캡처되어 3D로 복원된 얼굴 객체의 부위별 의미 있는 영역에 대한 분할을 자동으로 수행하는 기술을 제안한다. 3D 스캔된 얼굴 모델을 모델링, 애니메이션, 3D 프린팅 등의 다양한 응용분야에 활용하기 위해서는 스캔된 영역의 의미 있는 부위별 인식이 필수적이다. 본 논문에서는 부위별 의미 있는 영역 레이블링이 된 템플릿 모델을 입력된 3D 복원 모델로 전이하여 복원된 3D 모델의 부위별 의미 있는 영역을 자동으로 분할하고 분할된 영역의 일관성을 유지하는 알고리즘을 제안한다.

The characteristics of silicon nitride films deposited in a planar coil reactor using a simple high-density inductively coupled plasma chemical vapor deposition technique have been investigated. The process gases used during silicon nitride deposition cycle were pure nitrogen and a mixture of silane and helium. It has been pointed out that the strong H-atom released from the growing SiN film and Si-N bond healing are responsible for the improved electrical and passivation properties of SiN.

현재 우리의 7차 교육과정에서 교육의 보조 도구로써 교실에서 사용될 수 있는 것은 별로 많지 않다. 그래서 AvaLab은 이 시점에서 좋은 도구가 될 수 있다. AvaLab은 컴퓨터에 익숙하지 않은 학생을 위한 GUI 프로그래밍 도구이며, 현재의 교육 과정에서 필요로 하는 창의성을 키우기 위한 한 도구로써 교실에서 사용될 수 있다. 사용하려면, 먼저 학습자는 프로그래밍 아이디어를 생각하고, 아이콘 기반의 AvaLab을 통하여 프로그래밍한다. 프로그래밍 후에 학습자는 로봇의 결과를 생각하고 토론할 수 있다. 만약 그 결과가 정확화지 않다면, 로봇은 피드백을 보일 젓이다. 그러므로, AvaLab은 초보자를 위한 도구이며, 7차 교육과정에 적합한 도구이다. AvaLab의 특징 중 하나는 아이콘 기반의 흐름도 모델로 구성되어 있다는 것과 학습자는 입력과 출력 센스를 갖는 로봇을 이용해 실습할 수 있다는 것이다.

We present a system for generating 3D personalized figures. This system provides 3D figures model modification and combination functions based on the content-awareness. The integrity of the 3D model must be guaranteed at the time of slicing of the 3D model for 3D printing. In addition to this, with 3D printing, we generally have to print a hollow model in order to save money, time, and the integrity of the print. This paper proposes the automatic algorithm that creates the 3D individual figures with depth sensor and the easy UI functions for deformation, thickness adjustment, and combination of the generated 3D figures model based on the content-awareness. Our proposed method maintains the unique features of the generated 3D figures and ensures the successful 3D printing.

We reported the a-Si crystallization using a XeCl excimer laser annealing on the plastic substrate. The poly-Si film is able to grow in the low temperature and light substrate like a plastic. For the preparation of sample, substrate is cleaned by organic liquids. The film of $CeO_{2}$ layer as the buffer layer was grown by sputtering methods. After a-Si film deposition using ICPCVD, the film was crystallized by XeCl excimer laser. In this paper, we present the crystallization properties of a-Si on the plastic substrate

Three dimensional quantitative structure-activity relationship studies for a series of isatin derivatives as a nonpeptidyl caspase-3 enzyme inhibitor were investigated using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). The first approach of non-peptidyl small molecules by 3D QSAR may be useful in guiding further development of potent caspase-3 inhibitors.

We report the suitable SLS (sequential lateral solidification) as a function of laser intensity. Precursor film is changed from 50nm to 100nm and is deposited on glass substrate by PECVD. We can find the suitable SLS length by changing the mask size. In this paper, we present the well-defined grain growth conditions as a function of laser intensity.

This paper presents an Electrotactile Display System (ETCS). One of the most important human sensory systems for human computer interaction is the sense of touch, which can be displayed to human through tactile output devices. To realize the sense of touch, electrotactile display produces controlled, localized touch sensation on the skin by passing small electric current. In electrotactile stimulation, the mechanoreceptors in the skin may be stimulated individually in order to display the sense of vibration, touch, itch, tingle, pressure etc. on the finger, palm, arm or any suitable location of the body by using appropriate electrodes and waveforms. We developed an ETCS and investigated effectiveness of the proposed system in terms of the perception of roughness of a surface by stimulating the palmar side of hand with different waveforms and the perception of direction and location information through forearm. Positive and negative pulse trains were tested with different current intensities and electrode switching times on the forearm or finger of the user with an electrode-embedded armband in order to investigate how subjects recognize displayed patterns and directions of stimulation.
