  • Observational date is integral in our understanding of present climate, its natural variability and any cnange roue to anturopogenic effects. This study incorporates a brief overview of sampling requirements using data from the first ISLSCP Field Experiment (FIFE) in 1987, which was a multi-disciplinary field experiment over a 15km grid in Konza Prairie, USA. Sampling strategies were designed for precipitation and soil moisture measurements and also detecting land cover type. It was concludes that up to 8 raingages would be needed for valuable precipitation measurements covering the whole FIFE catchment, but only one soil moisture station. Results show that as new gages or station are added to the catchment then the sampling error is reduced, but the Improvement in error performance is less as the number of gages or stations increases. Sampling from remoteiy sensed instruments shows different results. It can be seen that the sampling error at 1arger resolution sizes are small due to competing error contribution from both commission and omission error.

  • Stochastic molecular dynamics simulation is a variation of standard molecular dynamics simulation that basically omits water molecules. The omission of water molecules, occupying a majority of space, enables flow simulation at microscale. This study reports our stochastic molecular dynamics simulation of particles diffusing in rectangular microchannels. We interestingly found that diffusion patterns in channels with a very small aspect ratio differ by dimensions. We will also discuss the future direction of our research toward a more realistic simulation of micromixing.

  • As a designer, Rei Kawakubo had become one of the most influential woman of the 20th century. Comme des Garçons, which means "like boys"-what women in the early 1980s were least supposed to be-expressed criticism of the prevailing social construct of women and, importantly, of the very concept of fashion. The press had a field day with the so-called post Hiroshima look, with its aesthetic of destruction, poverty, and hunger and with its depressing mood engendered by the use of the color black. This research divided the change of design transition on Kawakubo's fashion by the three categories. The first category was experimental pattern, the second category was esthetics of omission and the third category was innovation of body consciousness. The costume messages through these design works of Kawakubo could summarize 5 items, punk sprit, beyond sex, reality, proposal of new body consciousness and representation of black.

  • In this paper, we propose a style-specific language model adaptation scheme using n-gram based tf*idf similarity for Korean spontaneous speech recognition. Korean spontaneous speech shows especially different style-specific characteristics such as filled pauses, word omission, and contraction, which are related to function words and depend on preceding or following words. To reflect these style-specific characteristics and overcome insufficient data for training language model, we estimate in-domain dependent n-gram model by relevance weighting of out-of-domain text data according to their n-. gram based tf*idf similarity, in which in-domain language model include disfluency model. Recognition results show that n-gram based tf*idf similarity weighting effectively reflects style difference.

  • In the integral imaging system for 3D display, we have investigated the image distortions, such as duplication and omission, which are presented in the reconstructed image. We have also discussed the quantitative condition which minimizes the distortion, with several fundamental variables. In addition, we present the experimental results which support the quantitative analysis of the distortion.

  • 이 논문은 영어와 한국어에서 논 항구조의 교체를 허용하는 처소격 동사들의 통사구조와 의미를 비교 분석해 보려고 한다. 지금까지 연구가 논항구조의 교체를 허용하는 이런 동사들이 통사적 유사성에만 국한되어 연구가 되었을 뿐 여러 다른 통사적 형식에서 보여지는 차이점이나 논항 교체 동사들의 의미적 차이점과 같은 중요한 현상들에 대한 많은 연구가 되어지지 않았다. 따라서 첫 번째로 이 논문에서는 Pinker (1989)에 제시한 논항 교체 동사들의 의미적 분석을 구체적으로 소개하고, 이런 교체 동사들의 의미적 유사성과 차이점으로 구분한 Pinker의 의미분류들을 자세히 알아본다. 또한 Pinker가 교체동사들의 의미적 분류를 위해 사용한 통사적 기준인 논항 생략 (PP-omission test)을 소개한다. 두 번째로 영어의 논항 교체 동사들에 해당하는 한국어 동사들의 통사적 형태를 알아봄으로써 영어와 한국어에서의 통사적 유사성과 차이점을 알아본다. 세 번째로 영어와 한국어에서 나타나는 통사적 차이점의 설명을 위해 Pinker가제시한 의미 분류들을 수정한 새로운 분류를 제시한다 마지막으로 Jackendoff (1996)에서 제시된 의미적 설명이 영어의 논항 교체 동사에 해당하는 한국어 동사들의 통사적 형태들의 다양성을 설명할 수 있음을 보여준다

  • This paper studied a method for minimizing the noise level emitted from range hoods. Range hoods were used for discharging various hazardous materials generated during household cooking to the outdoors, thus preventing them from being diffused through rooms in the house since they are the main cause of air pollution within dwellings. This study assumed that static pressure was not applied at the discharge outlet of the range hood. As such, the range hood was installed on the wall without the use of a connecting duct or other connectors attached to its discharge outlet. The vibration having the greatest influence on the noise level was determined by measuring the vibration at the front side of the hood where the acoustic omission was at its maximum. A method was then proposed to reduce the noise by simply suppressing the vibration at the vibrating part.

  • The relation between the paper formation analyzer by image process system and smoothness, compressibility uniform of ink absorption is studied. There results indicate that the paper with bad formation has higher apparent bulk than the paper with good formation. The bad formation of paper results in the nonuniform calendering and decrease of the compressibility. The bad formation of paper also results in deformation and omission of printing dots, which affects the reproduction of the printing images.

  • In this study, Acoustic emission(AE) sensors were fabricated using lead-free piezoelectric ceramics for prohibiting environmental pollution. Structure of AE sensors were designed as Langvin type air backing form. Here, the piezoelectic element was used as PZT(EC-65)(AE1) and NKN(AE2), respectively. The measured resonant frequency, the maximum sensitivity frequency and sensitivity of AE sensors were as follows ; 143 kHz, 29.4 kHz and 69.3 dB in AE1 and 179 kHz, 29.4 kHz and 66.3dB in AE2, respectively.
