Objectives : The purpose of this case is to report the improvement after treatment about a patient with cerebral infarction by Sa-Am's Ohaeng-acupuncture and Liuqi-acupuncture. Methods : We treated the patient with acupuncture therapy from 6th September 2004 to 15th November 2004 by reinforcing Dadun(Liv 1) Zusan Li(S36) Quchi(Li 11) and reducing Taibai(Sp 3) on the basis of Etiological Analysis and Differenciation of Endogenous Wind caused by Damp Phlegm and heat. Results .1. Right hemiplegia improved Gr. I to Gr.IV after acupuncture therapy. 2. we interpreted 'reinforcing Dadun(Liv 1) and reducing Taibai(SP 3)'as using Simjeonggyeok in conjunction with Simseunggyeok on the basis of Sa-Am's Ohaeng-acupuncture. 3. we interpreted 'reinforcing Dadun(Liv 1) and reducing Taibai(Sp 3)'as Excreting Dampness in Spleen on the basis of Liuqi-acupuncture. 4. we interpreted 'reinforcing Zusan Li(S 36) and Quchi(Li 11)'as Eliminating Wind-dampness and Menstrual Regulation.

Different power output of solar cells can be observed at high-temperature regions such as desert areas. In this study, performance dependence on operating temperature of crystalline silicon solar cells with different emitter types was analyzed. Based on the light current-voltage (LIV) measurement, temperature coefficients of short-circuit current density ($J_{SC}$), open-circuit voltage ($V_{OC}$), fill factor (FF) and power conversion efficiency were measured and compared for two groups of crystalline silicon solar cells with different emitter types. One group had homogeneously doped (conventional) emitter and another selectively doped (selective) emitter. Varying the operating temperature from 25 to 40, 60, and $80^{\circ}C$, LIV characteristics of the cells were measured and the properties of saturation current densities ($J_0$) were extracted from dark current-voltage (DIV) curve. From the DIV data, effect of temperature on the performance of the solar cells with different electrical structures for the emitter was analyzed. Increasing the temperature, both emitter structures showed a slight increase in $J_{SC}$ and a rapid degradation of $V_{OC}$. FF and power conversion efficiency also decreased with the increasing temperature. The degrees of $J_{SC}$ increase and $V_{OC}$ degradation for two groups were compared and explained. Also, FF change was explained by series and shunt resistances from the LIV data. It was concluded that the degradation of solar cells shows different values at different temperatures depending on the emitter type of solar cells.

리튬이차전지용 양극물질로서 $LiV_3O_8$의 새로운 합성방법이 그 전기화학적 거동을 향상시키는 것으로 제안되고 있다. $LiV_3O_8$을 수용성 lithium trivanadate 겔의 탈수에 의해 잘 분산된 형태로 얻어진다. $LiV_3O_8$의 초음파처리방법은 solutionmethod에 의해 만들어진 초기상태의 $LiV_3O_8$과 비교된다. 수용액상에서 초음파처리 된 물질은 XRD, TGA, SEM등으로 물리적특성을 확인하였다. 이런 방법들은 수용성 $LiV_3O_8$의 초음파처리공정이 결정성을 감소시키고 비표면적과 공간용량을 향상시키는 것으로 나타났다. 특히 2시간 동안 초음파처리한 것은 높은 방전용량을 가지며, 대용량의 손실없이 충방전사이클이 이루어졌다. 따라서, 초음파처리 된 $LiV_3O_8$은 공간용량을 향상시킬 뿐만 아니라 사이클거동 역시 향상되었다.

Objective : Spinal cord injury (SCI) is a very serious health problem, usually caused by a trauma and accompanied by elevated levels of inflammation indicators. Stem cell-based therapy is promising some valuable strategies for its functional recovery. Nestin-positive progenitor and/or stem cells (SC) isolated from pancreatic islets (PI) show mesenchymal stem cell (MSC) characteristics. For this reason, we aimed to analyze the effects of rat pancreatic islet derived stem cell (rPI-SC) delivery on functional recovery, as well as the levels of inflammation factors following SCI. Methods : rPI-SCs were isolated, cultured and their MSC characteristics were determined through flow cytometry and immunofluorescence analysis. The experimental rat population was divided into three groups : 1) laminectomy & trauma, 2) laminectomy & trauma & phosphate-buffered saline (PBS), and 3) laminectomy+trauma+SCs. Green fluorescent protein (GFP) labelled rPI-SCs were transplanted into the injured rat spinal cord. Their motilities were evaluated with Basso, Beattie and Bresnahan (BBB) Score. After 4-weeks, spinal cord sections were analyzed for GFP labeled SCs and stained for vimentin, $S100{\beta}$, brain derived neurotrophic factor (BDNF), 2',3'-cyclic-nucleotide 3'-phosphodiesterase (CNPase), vascular endothelial growth factor (VEGF) and proinflammatory (interleukin [IL]-6, transforming growth factor $[TGF]-{\beta}$, macrophage inflammatory protein [MIP]-2, myeloperoxidase [MPO]) and anti-inflammatory (IL-1 receptor antagonis) factors. Results : rPI-SCs were revealed to display MSC characteristics and express neural and glial cell markers including BDNF, glial fibrillary acidic protein (GFAP), fibronectin, microtubule associated protein-2a,b (MAP2a,b), ${\beta}3$-tubulin and nestin as well as anti-inflammatory prostaglandin E2 receptor, EP3. The BBB scores showed significant motor recovery in group 3. GFP-labelled cells were localized on the injury site. In addition, decreased proinflammatory factor levels and increased intensity of anti-inflammatory factors were determined. Conclusion : Transplantation of PI-SCs might be an effective strategy to improve functional recovery following spinal cord trauma.

Objective : Carthami Flos has been used as a herb to promote blood circulation to remove blood stasis in oriental medicine for many centuries. To investigate treatment of cerebral vascular disease(CVA) by promoting blood circulation and removing blood stasis(活血化瘀法), we observed the experimental Effects of Aqua-Acupuncture of Carthami Flos on the Regional Cerebral Blood Flow and Mean Arterial Blood Pressure in Rats. Method : When aqua-acupuncture of Carthami Flos(ACF) was injected into LI4, Liv3, B23, B62, GV16, experimental effects of ACF on the regional cerebral blood flow(rCBF) and mean arterial blood pressure(MABP) is not known. Therefor, this study was designed to investigate the effects of ACF on the change of cerebral hemodynamics. The changes of rCBF and MABP were tested by Laser Doppler Flowmetry(LDF). Results : When ACF was injected into LI4, change of rCBF and MABP were decreased in a injected time-dependent manner. When ACF was injected into Liv3, change of rCBF and MABP were decreased in a injected time-dependent manner. When ACF was injected into B23, change of rCBF was significantly increased in a injected time-dependent manner, MABP did not change. When ACF was injected into B62, change of rCBF was increased in a injected time-dependent manner, change of MABP was significantly decreased after injection 60min. When ACF was injected into GV16, change of rCBF and MABP were similar to the change of normal. Conclusions : In conclusion, I suggested that ACF(LI4, Liv3) has an effect that depress the blood pressure & cerebral hemodynamic acceleration and ACF(B23, B62) has an anti-ischemic effect through the improvement of crebral hemodynamics.

5살의 수컷 치와와가 상악골의 극세포 유래 치은종양의 치료를 위해 플로리다 수의과 대학의 한방 진료과를 내원하였다. 환자를 위해 한약요법과 함께 한달 간격으로 침술요법을 적용하였다. 침자리와 한약은 환자의 한방적인 진단에 근거하여 선택되었다. 사용된 침자리는 족삼리(ST36), 퓽흉(ST40), 공손(SP4), 삼음교(SP6), 비수(BL20), 위수(BL21), 태충(LIV3), 백회(GV20)이었고, 한약으로는 내소환(內消丸: Nei Xiao Wan)과 사군자탕(四君子湯: Si Jun Zi Tang)을 사용하였다. 침술요법과 한약을 적용한지 1년 후 관찰한 결과 극세포 유래의 치은 종양이 현저하게 줄어든 것을 확인하였다. 이것으로 보아 개의 극세포유래 치은종의 치료에 있어 대체요법인 침술과 한약요법이 유용할 수 있다고 생각된다.

최근 지문 인식을 통한 사용자 인증 기술이 상용화 되면서 위조 지문 이미지 판별이 더욱 중요해졌다. 본 논문에서는 CNN 특징을 이용한 위조 지문 이미지 판별 방법을 제안하였으며, CNN 모델이 실제 지문의 어느 부분에 반응하여 위조지문을 분류하는지 시각화 방법을 통해 분석하였다. 제안하는 방법은 지문영역과 배경영역을 분리하는 전처리 작업 후 CNN 모델을 이용하여 지문의 위조여부를 분류한다. 지문을 단순히 생체지문과 위조지문으로 분류하는 것이 아니라 위조지문을 구성하는 물질별로 분류하여 생체지문과 위조지문들에 대한 특징분석을 제공한다. 실험에 사용한 데이터베이스로는 생체 지문 이미지 6500여 장과 위조 지문 이미지 6000여 장으로 구성되어 있는 LivDet2013을 사용하였으며 위조여부에 대한 ACE 값으로 3.1%, 구성 물질 분류 정확도는 평균 79.58%를 보여 높은 수준의 분류성능을 갖고 있음을 확인하였다.
