본 연구에서는 홍차 흑효모 발효물의 기능성화장품 소재로서의 가능성을 규명하고자 항산화, 미백, 항주름 효능을 확인하였다. 홍차 흑효모 발효물의 결과는 홍차 추출물, 흑효모 발효물과 비교하여 나타내었다. 항산화능 평가 결과 홍차 흑효모 발효물은 흑효모 발효물보다 뛰어난 DPPH 라디칼 소거능을 나타냈으며 홍차 추출물과는 유사한 결과를 나타냈다. 과산화수소로 유도된 세포 내 활성산소종 실험에서도 홍차 흑효모 발효물은 유의적 제거 활성을 보였다. 또한 홍차 흑효모 발효물은 tyrosinase 저해 활성을 보이며 Melan-a, B16F10 세포를 이용한 멜라닌 형성이 억제됨을 확인하였다. 항주름 효능 확인을 위해 콜라겐 분해 효소(MMP-1)를 측정한 결과 홍차 흑효모 발효물이 홍차 추출물, 흑효모 발효물보다 높은 항주름 활성을 보였다. 본 연구 결과를 통해 홍차 흑효모 발효물은 항산화능 효능을 보이며 미백, 항주름 효능을 보아 기능성 화장품 소재로 개발될 수 있음을 확인하였다. In this study, anti-oxidant, whitening and anti-aging effects were investigated the possibility of fermented black tea yeast as a functional cosmetic material. The results of Aureobasidium pullulans (A. pullulans) ferment of black tea (AFBT) were compared with black tea (BT) and A. pullulans ferment (AF). The antioxidant activity of the AFBT product showed DPPH radical scavenging ability higher than that of AF. In the intracellular ROS experiments induced by hydrogen peroxide, the AFBT showed significant decreased activity. In addition, AFBT showed tyrosinase inhibitory activity and inhibited the formation of melanin using Melan-a and B16F10 cells. Through suppression of MMP-1 expression, the AFBT showed higher anti-wrinkle activity than BT and AF. From the results of this study, it was confirmed that AFBT showed antioxidant activity and was developed as a functional cosmetic material based on whitening and anti-wrinkle efficacies.

A head-neck complex dummy, for measuring brain pressure and reaction force in the cervical spine was developed for experimental study related in injury mechanism. Dummy comprised aluminium-casted head with water filled cavity for simulating brain and mechanical neck assembled with six motion segments. Several kinds of experiments (compression, bending, cyclic modulus, relaxation and constant velocity profile) for the developed mechanical neck showed that this neck model is biomechanically reliable compared with in-vitro test results. As an application of developed head-neck complex dummy, shock absorbing properties of protective helmet was chosen. The experiments showed that the maximum pressure increment of brain after impact was tolerable compared with the guide line for mild brain injury pressure (25psi). Constrast to this results, the reaction force in the neck was high enough to produce failure in the cervical spine.

김영은,홍수형,김정완,이종영,Kim, Yeong-Eun,Hong, Su-Hyung,Kim, Jung-Wan,Lee, Jong-Young 대한예방의학회 2006 예방의학회지 Vol.39 No.2
Objectives : The determination of oxalate in urine is required for the diagnosis and treatment of primary hyperoxaluria, idiopathic stone disease and various intestinal diseases. We examined the possibility of using Fourier transform near-infrared (FT-NIR) spectroscopy analysis to quantitate urinary oxalate. The practical advantages of this method include ease of the sample preparation and operation technique, the absence of sample pre-treatments, rapid determination and noninvasiveness. Methods : The range of oxalate concentration in standard urine solutions was $0-221mg/{\ell}$. These 80 different samples were scanned in the region of 780-1,300 nm with a 0.5 nm data interval by a Spectrum One NTS FT-NIR spectrometer. PCR, PLSR and MLR regression models were used to calculate and evaluate the calibration equation. Results : The PCR and PLSR calibration models were obtained from the spectral data and they are exactly same. The standard error of estimation (SEE) and the % variance were $10.34mg/{\ell}$ and 97.86%, respectively. After full cross validation of this model, the standard error of estimation was $5,287mg/{\ell}$, which was much smaller than that of the pre-validation. Furthermore, the MCC (multiple correlation coefficient) was 0.998, which was compatible with the 0.923 or 0.999 obtained from the previous enzymatic methods. Conclusions : These results showed that FT-NIR spectroscopy can be used for rapid determination of the concentration of oxalate in human urine samples.

Recently, many researchers have been interested in children with phonological disorders. The purpose of this study was to examine those children in comparison with normal children and to find better assessment criteria of the whole-word approach. Three children with phonological disorders and three normal children of 5 to 7 years old participated in the picture description tasks. Results of this study were as follows: there was a significant difference in the whole-word assessment between normal and phonological disorder children. Such criteria as whole-word correctness, whole-word complexity, whole-word intelligibility proved to be good for diagnosing children's phonological disorders. Further studies would be desirable to apply the approach to more children of various age groups.

최근 들어 많은 관심에 대상이 되고 있는 동차 사고시 어린이 승객의 부상현상을 해석하기 위하여 범용 동력학 패키지인 DADS를 이용하여 3세 어린이 모델을 개발하였다. 모델은 모두 14개의 요소들과 12개의 조인트로 구성 시켰으며 부스터를 장착한 시트에 3점식 벨트를 체결한 형태로 개발되었으며 썰매를 이용한 전방 충돌 시뮬레이션 결과 기존의 더미를 이용한 실험 결과와 일치하는 응답 특성을 얻을 수 있었다. In order to increase our understanding of the injury mechanism in the child occupant, three year old child model was developed using commercial dynamic package DADS. Total 14 segments and 12 joints were used to compose a model in three points belted condition with booster seat. HYGE sled test case was simulated to validate the developed model. Based on the comparison of the model and published test results, the developed model appears to be a resonable representation of the three year old dummy.

Human embryonic stem (ES) cells are a potential source of cells for developmental studies and for a variety of applications in transplantation therapies and drug discovery. However, human ES cells are difficult to culture and maintain at a large scale, which is one of the most serious obstacles in human ES cell research. Culture of human ES cells on MEF cells after disassociation with accutase has previously been demonstrated by other research groups. Here, we confirmed that human ES cells (H9) can maintain stem cell properties when the cells are passaged as single cells under a feeder-free culture condition. Accutase-dissociated human ES cells showed normal karyotype, stem cell marker expression,and morphology. We prepared frozen stocks during the culture period, thawed two of the human ES cell stocks, and analyzed the cells after culture with the same method. Although the cells revealed normal expression of stem cell marker genes, they had abnormal karyotypes. Therefore, we suggest that accutase-dissociated single cells can be usefully expanded in a feeder-free condition but chromosomal modification should be considered in the culture after freeze-thawing.

NiO 산화물 타겟을 이용한 RF 마그네트론 스퍼터 방법으로 유리 기판 위에 NiO 박막을 Ar 가스만을 사용하여 증착하였으며, 증착 온도에 따라 NiO 박막 특성에 미치는 영향을 조사하였다. XRD 측정으로부터 증착된 박막의 결정구조는 $200^{\circ}C$ 이하에서 (111) 면의 우선 배향성으로 보이다가 $350^{\circ}C$ 이상에서 (220) 면의 우선 배향성을 가지는 다결정 입방구조임을 확인하였다. NiO 박막의 전기적 특성의 변화는 기판의 온도가 $200^{\circ}C$까지는 $10^5\;{\Omega}cm$의 부도체에 가까운 높은 비저항을 보였고 기판의 온도가 $300^{\circ}C$ 이상에서는 $10^{-1}{\sim}10^{-2}{\Omega}cm$의 도체의 특성을 보이는 낮은 비저항으로 감소하는 Mott-Insulator Transition(MIT) 현상을 관측하였다. NiO 박막 내의 증착 온도 변화에 따른 ${\sim}10^7$ 정도의 큰 비저항 변화를 결정성, 결정립의 변화 및 밴드 갭의 변화 등으로 설명하였다. Polycrystalline NiO thin films were deposited on glass substrate by RF magnetron sputtering using only Ar as a plasma sputter gas. based on the analysis of x-ray diffraction (XRD), NiO films had a polycrystalline cubic (NaCl type) structure. NiO thin films grown below and above $200^{\circ}C$ showed preferred orientation of (111) and (220) respectively. It showed colossal change in electrical resistivity as much a ${\sim}10^7$ order form an insulating state of $105\;{\Omega}cm$ below $200^{\circ}C$ to a conducting state of $10^{-2}{\sim}10^{-1}\;{\Omega}cm$ above $300^{\circ}C$ such a Mott metal-insulator transition (MIT) in polycrystalline.
