In this study, Rheoencephalography(REG) was designed and constructed. Using the constructed instrument cerebral blood flow(CBF) of left and right brain, CBF change by posture, and reproducibility were studied. Followings are important results. Relative CBF could be measured noninvasively and continuously. Since reproducibility of the constructed REG was found to be quite high (4 %), the accuracy of the instrument itself was proved. REG can be easily applied for testing the effect of drugs for the patients with cerebral vessel diseases since it is quite sensitive to the relative changes of CBF. Various cerebral diseases can be diagnosed by analyzing the REG waveforms. The area of restricted cerebral blood vessels can be located by arranging the electrode configuration. Comparative studies with the standard techniques of measuring CBF are needed to verify the accuracy of REG. Further studies on optimal electrode configuration and various artifacts are also necessary.

Full-overlapped gravitational field energy uses the overlapping gravitational fields formed by superimposing the forces exiting the earth to the ground and the forces on a number of stars. This study investigated the physicochemical, antioxidative, and organoleptic properties of burdock tea treated by full-overlapped gravitational field energy (FGFE). We measured the color, turbidity, pH, soluble solid/sugar/phenol contents, and antioxidant activity of the extracts of the FGFE-treated and non-treated burdock tea. The FGFE-treatment increased the soluble solid contents and pH, but decreased the turbidity, brownness, and total phenolic contents. When the response surface methodology was used to characterize the extraction efficiency of the burdock tea, it was identified that the FGFE-treatment resulted in the burdock tea having different responses to the extraction time and temperature. More specifically, the FGFE-treated burdock tea was less dependent on the extraction temperature than the non-treated one. Meanwhile, the overall organoleptic acceptability was increased by the FGFE-treatment. In conclusion, the FGFE-treatment changed the extraction efficiency and biochemical properties of the burdock tea extract, which might have affected its organoleptic quality. In conclusion, this study confirmed that recovery through non-material energy can lead to significant changes in the production of burdock tea.

파렛트는 아주 단순한 운반도구 또는 적재 깔판으로 인식될 수 있지만, 화물을 싣고 달리는 운반용 도구로서 물류의 흐름과 기 능을 통합적으로 연결하는 중요한 연결 매개체 역할을 한다. 하역작업의 생산성과 화물의 운반 활성도를 높이려면 표준파렛트를 사용하여 화물의 적재단위를 대형화하고 기계화 및 자동화를 추진해야 하며, 표준화된 유닛로드시스템을 통하여 공급망의 전체 최적화를 구축해야 한다. 이를 위해서는 산업 현장에 파렛트의 생산과 사용부문에 대한 실태조사와 연구가 가장 우선적으로 선행 되어야 한다. 본 연구는 그동안 (사)한국파렛트컨테이너협회에서 수행하였던 파렛트 및 컨테이너의 실태조사 결과를 토대로 시계 열 분석을 하는 것이다. 우리나라 파렛트 표준규격은 2013년부터 T-11형과 T-12형 두 종류를 일관수송용 표준규격으로 채택하고 있으며, 그동안 조사결과에 따르면 파렛트 규격(치수)에 따른 생산과 사용의 비중은 T-11형이 약 40%, T-12형은 약 13∼14% 수준 으로 집계되었으며, 파렛트 재질에 따른 생산과 사용의 비중은 플라스틱이 약 50%, 목재 재질이 약 40%의 수준을 보이고 있다. The pallet can be perceived as a very simple transport tool or a loading board, but it serves as an important coupling medium for integrating logistics flow and function as a transport tool that is shipping and loading freight. In order to increase the productivity of the unloading operation and the transport activity index cargo, the loading unit of the cargo shall be large, mechanized and automated using a standards pallet, and the overall optimization of the supply chain shall be established through the unit road system using standard pallets. To this end, time sequential analysis of survey and research on the production and usage of pallets at industrial sites should be carried out firstly. This study is based on the results of the status surveys which is the pallets and containers conducted by the Korea Pallet Container Association for the most recently survey in 2018. The Korean standard for pallet has adopted two types of T-11 and T-12 as standard standards for through transit pallets since 2013. According to the findings, the proportion of production and usage according to the pallet standard (dimensions) is roughly 40 percent for T-11 type and 13 to 14 percent for T-12 type, and the proportion of production and usage by the pallet material is roughly 50 percent for plastics and 40 percent for wood materials.

JP-7/산소 혼합기의 데토네이션 파 특성을 상세 반응 기구로부터 얻은 일 단계 유도변수 모델을 (IPM) 이용하여 살펴보았다. 탄화수소 혼합기에 대한 상세 화학 반응 모델로 부터 신뢰할 만한 일 단계 반응 모델을 얻기 위한 일반적 과정을 본 연구에서 제시하였다. IPM은 상세 반응 모델 라이브러리로부터 획득한 유도 시간 데이터베이스를 재구성하여 얻었으며, 상세 반응 모델에 의한 결과와 비교하여 확인하였다. 이후 IPM을 유체역학해석 코드에 적용하였으며, 데토네이션 파 전파에 대한 수치해석에 이용하였다. 수치해석 결과는 탄화수소 연료 연소의 상세 반응 기구를 직접 적용해서는 가능하지 않은, JP-7/산소 혼합기의 데토네이션 파 전파 특성의 상세한 특징을 보여주었다. The detonation wave characteristics of JP-7 and oxygen mixture is investigated by one-step induction parameter model (IPM) obtained from a detailed chemistry mechanism. A general procedure of obtaining reliable one-step kinetics IPM for hydrocarbon mixture from the fully detailed chemistry is described in this study. The IPM is obtained by the reconstruction of the induction time database obtained from a detailed kinetics library. The IPM was confirmed by the comparison of the induction time calculations with that from detailed kinetics. The IPM is later implemented to a fluid dynamics code and applied for the numerical simulation of detonation wave propagation. The numerical results show the detailed characteristics of the detonation wave propagation in JP-7 and oxygen mixture at affordable computing time, which is not be possible by the direct application of the detailed chemical kinetics mechanism of hydrocarbon fuel combustion.

In this paper the intent recognition system which recognizes the human's head motion as a simple non-linguistic intent representation is presented. The system recognizes four basic intent representations, such as strong/weak affirmation and strong/weak negation by image processing of nodding or shaking motion of human's head. The vision system for tracking the head motion is composed of CCD camera image processing board and personal computer The modified template matching method which replaces the reference image with the searched target image in the previous step is used for the robust tracking of the head motion. For the improvement of the processing speed, the searching is performed in the reduced regions based on the pyramid structure. By inspecting the variance of the head motion trajectories, we can recognizes the two basic intent representations - affirmation and negation. Also, by focusing the speed of the head motion, we can see the strength of the intent representation.
