고려인삼(Panax Ginseng C. A. Meyer)은 오갈피나무과(Araliaceae) 인삼속(Panax)에 속하며 4-6년 동안 그늘진 곳에서 재배되는 다년생 초본식물이다. 인삼은 현재 우리나라뿐만 아니라 중국, 일본, 미국, 캐나다, 소련 등지에서 재배되고 있으나 우리나라 인삼은 "고려인삼"이라는 별칭으로 유통되고 있다. 이것은 고려인삼이 다른 인삼보다 월등히 품질이 우수하기 때문으로 판단하고 있다(고 등,1994). 인삼제품중 원형을 유지하는 건조제품으로는 홍삼, 백삼, 태극삼 등이 있으며 그동안 홍삼류는 국가 전매사업 대상으로서 한국담배인삼공사에서 조제, 가공 판매를 하였으나 1998년부터는 일반인도 취급이 가능하게 되었다. 홍삼은 원료수삼을 약 9$0^{\circ}C$ 이상의 증기로 증삼하기 때문에 이 과정에서 매우 유용한 약용 물질이 생성되는 것으로 알려져 있어 백삼보다 가공비는 높으나 가격이 매우 높기 때문에 일반 인삼가공업자들이 홍삼제조를 선호하고 있다 또한 동남아나 중국 등지에서 고려 홍삼을 선호하기 때문에 더욱 그러한 경향이 나타나고 있다.

The compressed injection yellow ocher soil is the process-technology by drying the product through sunshine, not by firing like pottery and ceramic ware. It is the technology of development being able to achieve the far infrared ray and humidity adjustment by adding recycling paper, Korean paper and bamboo salt, and it corresponds with the construction enforcement ordinance 2007 as an interior-finishing product which is fire-resistant. In case that the yellow ocher soil would be used as lighting device and interior-finishing material and decoration, it could contribute to an improvement of National Health by avoiding the sick house syndrome and adding humidity adjustment, and it has more efficient economic effect due to using recycle-available additives. Through such developments of the yellow ocher soil products the domestic market of lighting device and construction material can be advanced and the replacement effect of imported goods & also export effect can be expected accordingly.

원적외선 세라믹 건조기를 개발하기 위하여 탄화규소가 주원료로한 세라믹 발열판을 제작하여 건조기 내부에 설치하여 실험하였다. 발열판 장착위치에 따른 실험결과 위치는 큰 변수가 되지 않았고, 기존 5[kW]용량의 씨즈 히터를 2[kW]의 세라믹 발열판으로 대체하면서 에너지절약형 원적피선 세라믹 건조기를 제작할 수 있었다. 또한 발열판 자제 온도 분포를 측정한 결과 시간이 흐름에 따라 온도 분포는 약진의 차이가 있기는 하지만 대체적으로 근일한 분포를 나타내었다. 사용에 따른 경년변화를 측정하기 위해 90시간 동안 부하를 걸어 실험하였지만 발열판 자체의 저항이나 소비 전력의 변화는 나타나지 않았다.

We have many environmental problems by the polluted materials as a results of mechanical development these days. So people want to use building products made from natural things and take a good effect for people from those bio products. We can instance electron wave shelding, far infrared ray and anion emission, and anti-bacterial property as the latest trend of the bio building material. So we had a experiment to investigate how much bio materials affect concrete when we use in the concrete with cement substitution. We tested slump, 7days compressive strength, and air contents for physical properties of bio concrete. The result is that bio concretes with four bio ingredients have proper values comparing with target values for slump and air content but lower compressive strength than plain concrete.

지금까지 우리나라 벼농사는 고품질 쌀의 생산보다는 다수확재배기술로 생산량을 늘리는 것이 농가소득에 유리하였다. 그러나 소비수준이 높아지고 쌀의 제고가 충분한 현시점에서는 풀질의 경쟁력 향상이 더욱 중요하다 이를 위해서는 고품질 쌀 생산을 위한 건조, 저장, 가공 등 기반시설의 현대화하여 브랜드화에 의한 차별화를 통하여 소비자의 신뢰를 얻기 위한 연구가 수행되어야 할 것이다. 쌀의 밥맛을 결정하는 요인은 품종, 재배, 관리, 수확에 이르기까지 관계가 있겠지만, 수확후처리 공정과정에서도 품질의 우열이 좌우된다 특히 건조 중 열풍온도 관리 소홀로 인하여 과건이 되는 경우에는 밥맛에 치명적이라고 할 수 있다.

The high quality and a nearly stoichometric growth of $Cd_{1-y} Zn_y$/Te(y＝0.04) epilayers have been successfully grown on GaAs substrate by hot wall epitaxy (HWE) by optimizing the growth condition including the preheating treatment and Cd reservoir temperature. The relationship between quality and thickness was examined and best value of FWHM from X-ray rocking curve of 121 arcsec are obtained. Also, emission peaks related to the recombination of free excitons such as the ground state and the first excited state were observed in the PL spectrum at 4.2K. The ($A^0$, X) emission related to Cd vacancy and deep level emission was not measured. These results indicated that the grown CZT/GaAs epilayer was high qualify and purity.

This is the experimental study on the functional property of the light-weight concrete according to the mineral composite. According to the increase of the functional mineral, Autoclaved light-weight concrete (ALC) have a effect of high far infrared ray, deodorization, anion and change of chromaticity on D65 of light source. Compressive strength and change of specific gravity by foaming of Mixed Slurry in accordance with additive rates and Water. It chracterizes surface by SEM, chemical component and crystallization by XRD, XRF. the results of this experiment studied influences of ALC by functional minerals.

Structure in the universe forms hierarchically with the small scales forming first and merging into larger scales. Galaxy clusters are at the pinnacle of the formation process. Peering far into the universe, we can observe galaxy clusters early in their evolution. SpARCSJ1049+56 is a galaxy cluster located at a redshift of 1.71. It has been shown to be rich in cluster galaxies, to have intense star formation, and to have a significant amount of molecular gas. Through careful control of systematics, we detected the weak-lensing signal from this distant galaxy cluster. I will present our HST infrared weak-lensing detection of the cluster with a focus on the method. Our lensing analysis found that the cluster is massive and is rare in a LambdaCDM universe. I will also present the Chandra X-ray discovery of cold gas coincident with the intense star formation and discuss the implications of the detection.
