Since GPS receivers and INS algorithms do not work properly in the spinning vehicles due to change of the GPS signal and excess of the measurement limitation of the gyroscope, conventional GPS/INS integrated navigation systems do not provide accurate navigation outputs. This paper proposes a design method for GPS/INS integrated navigation systems of spinning vehicles. A special GPS receiver with a signal tracking loop for changed GPS signal caused by spinning and an INS with a roll estimation method are configured and the conventional integration filter is combined. The proposed method was verified through comparison of the navigation results. The result of the proposed method for the spinning vehicle was similar to that of the conventional navigation system without spinning.

김정원,김주영,최승범,한상욱,이재철,김동훈,Kim, Jeong-Won,Kim, Choo-Young,Choi, Seung-Peom,Han, Sang-Wook,Lee, Jae-Chul,Kim, Dong-Hoon 대한약침학회 2010 Journal of pharmacopuncture Vol.13 No.4

본원에서 방아쇠 수지 환자 3례를 자하거 약침으로 5-7회 치료한 결과 유의한 효과가 있었다. 그러나 연구자의 치료예가 부족하여 4도 정도로 굴건의 걸림이 심한 경우나, 양방의 보존적 치료 후 재발되는 경우, 증상이 오래된 경우에 대한 연구와 1년 후의 재발율에 대한 추적 조사가 더 필요한 것으로 생각된다. 그리고 방아쇠 수지를 급성기, 결절형의 염증상태와 만성기, 미만형 퇴행상태로 정확하게 구분하여 염증상태에는 봉약침을 사용하고, 퇴행화 상태에서는 자하거 약침을 사용한다면 좋은 효과를 볼 것으로 기대된다. 앞으로 각종 수지관절 및 건의 질환에 대한 치료방법에 대한 연구가 더욱 더 필요할 것으로 생각된다. Objectives : The Purpose of this study is to investigate and report the effectiveness of Hominis Placenta using Pharmacopuncture treatment for trigger finger. Methods : 3 Patients are admitted at Dept. of Oriental Rehabilitation, Bu-Chun Jaseng Oriental Medicine Hospital, diagnosed as Trigger finger and treated with Hominis Placenta Pharmacopuncture. Each cases are measured and assessed by Quinnell's classification of triggering and VAS (Visual Analogue Scale) scores. Results : 3 Patients of trigger finger have a different kind of cause and fingers lesion they have, but nodules are not significantly found up, so we could classify all of 3 patients to diffuse type. After treatment of Hominis placenta Pharmacopuncture, spontaneous pain and tenderness, grades of triggering are decreased significantly. We would expect that Hominis placenta Pharmacopuncture has a effect on degenerative diseases of diffuse type's tendon sheath. Conclusions : Trigger finger is generally divided into two stages, inflammatory and degenerative stage, and when degenerative stage, Hominis placenta pharmacopuncture appears to be effective.

N/A The pulsed dye laser(Candela SPTL-1) is a flashlamp excited dye laser, using the principles of selective photothermolysis that selectively targets the abnormal microvasculatures of cutaneous lesion while sparing adjacent structures including the epidermis, emitting at 585nm wavelength, pulse duration of 450 ?sec and 5㎜ spot size. During the period of 6 months from April to September 1989, at O.P.D., Department of Dermatology, Ewha Womans University Hospital, 106 patients with cutaneous vascular lesions were analyzed to evaluate the clinical effects by the pulsed dye laser. The results were as follows: 1. Patient distribution of the cutaneous vascular lesions included 66 patients with nevus flammeus, 29 with telangiectasia, 8 with strawberry heniangioma and 3 with cavernous hemangioma. 2. Clinical effects a. Nevus flammeus : 73.0% of adults and 50.0% of children showed excellent or good results. b. Telangiectasia : 89.6% of patients showed excellent or good results. c. Hemangioma : 50.0% of patients with strawberry hemangioma and 66.7% of patients with cavernous hemangioma showed good results. d. Complications included transient hyperpigmentation(24.5%), hypopigmentation(5.7%) and atrophic scar(5.7%). There was no posttreatment s?lerosis or hypertrophic scarring.

본 실험에서는 탈지 유채박 중 표면활성물질의 추출을 위해 초임계 $CO_2$ 유체 추출법을 이용하였다. 추출 독립변수는 추출압력(150~350 bar), 온도($33{\sim}65^{\circ}C$), 보조용매량(ethanol, 150~250 g)으로 하였으며, D-optimal design에 의한 반응표면 분석을 통해 추출수율, 중성지질 분획, 인지질 분획, 당지질 분획 함량 등의 종속변수에 대한 최적 추출조건을 검토하였다. 그 결과, 압력, 온도, 그리고 보조용매량이 증가함에 따라 종속변수 즉, 추출수율, 인지질, 당지질 함량 등은 증가하였으나, 중성지질 함량은 감소하는 것으로 나타났으며, 그중 보조용매량이 각 종속변수에 가장 큰 영향을 주는 것으로 나타났다. 본 연구를 통해서 유도된 회귀식 모형은 실험을 통해 얻은 결과와 잘 일치하였으며, 초임계 $CO_2$ 유체 추출에 있어서 종속변수인 추출수율, 인지질, 당지질 함량 등을 최대로 하면서 중성지질 함량을 최소로 하는 최적화된 추출조건은 추출압력 350 bar, 추출온도 $65^{\circ}C$, 보조용매량 228.55 g으로 분석되었으며, 이 조건에서 추출수율은 5.98%, 추출물은 중성지질 3.0%, 인지질 69.43%, 당지질 17.46% 등의 조성을 나타낼 것으로 예측되었다. In this study, an attempt is being made to extract surface-active substances from defatted rapeseed cakes by supercritical carbon dioxide fluid. Independent variables for the extraction process, being formulated by D-optimal design, are pressure (150~350 bar), temperature ($33{\sim}65^{\circ}C$ and co-solvent (ethanol, 50~250 g). The dependent variables of the extraction yield, the content of neutral lipids, phospholipids and glycolipids in the extracts were analyzed upon the results through the response surface methodology. As for the extraction yield, it was found to increase with increasing independent variables, among which the co-solvent proved to be a major influencing parameter. Similar trends were found for the content of surface-active substances (i.e, phospholipids and glycolipids) in the extracts, except for the content of neutral lipids. Regression equations were suggested to coincide well with the results from the experiments. Extraction conditions are being optimized to maximize the extraction yields, the content of phospholipids, and glycolipids were 350 bar (pressure), $65^{\circ}C$ (temperature) and 228.55 g (co-solvent), respectively.

Objectives This study investigated the effects of Cheongyeonsan for allergic rhinitis. Methods First, the GS/MS was used to analyze the effects of Cheongyeonsan by measuring inflammatory markers. Second, 3 groups of 10 6-week-old BALB/c mice were divided into Ctrl (no treatment), ARE (allergic rhinitis-induced without treatment), and CRT (allergic rhinitis-induced after Cheongyeonsan treatment) groups. Ovalbumin (OVA) was used as an antigen to induce allergic rhinitis and sensitization was performed by intraperitoneal injection of 0.1% OVA solution 21, 14, and 7 days before the onset of allergic rhinitis. Allergic rhinitis was induced by dropping OVA solution on the nasal cavity of each mouse for 5 days after the last sensitization. Seven days after the first induction, second induction was introduced by the same method. After making the section, MMP-9, substance P, $TNF-{\alpha}$, $NF-{\kappa}B$ p65, COX-2, iNOS and Nrf, apoptotic cells were observed by Masson trichrome staining, immunohistochemical staining, TUNEL of nasal mucosal tissues of each group. Results GC/MS results showed undecanoic acid. Masson trichrome results showed that the CRT group had less respiratory epithelial damage. Immunohistochemical staining showed CRT group had 58% decrease in MMP-9, 61% decrease in substance P, 55% decrease in $TNF-{\alpha}$, 38% decrease in $NF-{\kappa}B$ p65, 53% decrease in COX-2, 54% decrease in iNOS, 87% increase in Nrf compared to those of the ARE group. TUNEL showed a positive reaction of 84% increase in apoptotic cells greater than that of the ARE group. Conclusions Cheongyeonsan alleviates nasal mucosal damage and reduces inflammatory mediators from allergic rhinitis-induced mice.

고체표면의 비점유 전자에너지 상태를 연구하고자 역광전자분광기를 제작하고 시험하였다. 이 분광기는 초고진공 챔버속에 전자총과 광검출기로 구성되어 있다. 전자총은 궤도 시뮬레이션과 전류 측정을 통해 좋은 집속도와 높은 전류밀도를 가지고 있음을 알 수 있었다. 이 분광기의 전체적인 분해능은 0.74 eV이고, 광검출기의 감도는 약 10 counts/$sec{\cdot}{\mu}A$이다. 하나의 결과로서 Ge(111) 시료의 역광전자분광 스펙트럼은 이론적인 계산결과와 잘 일치하였다. An inverse photoemission spectrometer has been built and tested to study the unoccupied electron energy states of solid surfaces. It consists of a low energy electron gun and a band pass photon detector in an ultra-high vacuum chamber. The electron ray tracing simulation and current measurement of the electron gun show a good focus and a high flux of electron current. The overall resolution of the spectrometer is 0.74 eV and the sensitivity of the photon detector is about 10 counts/$sec{\cdot}{\mu}A.$ As a test experiment, the inverse photoemission spectra of a Ge(111) sample is in good agreement with the theoretical result.
