Gullian Barre Syndrome is an acute symmetric polyradiculoneuropathy that typically presents as a progressive flaccid paralysis. The pathology is believed to be caused by both cellular and humoral immune processes The possibility of death is 3-5% and About 20% of patients require mechanical ventilaton. Recently We have experienced a patient who had suspected Gullian Barre Syndrome for 60days, his condition weakness and pain was impoved through the herb and acupucture Therefore I reported it for the treatment.

It is essential that we put the anticoagulant into the blood specimen of the CBC test. However, the value of some parameters in the CBC test can be changed whenever using some anticoagulants. EDTA anticoagulant is mostly used these days. There are 3 kinds of EDTA, that is K_(2-), K_(3-), and Na_(2-) EDTA. The author studies how many effects each the EDTA gets into the true value of blood specimen for MCV of RBCs. Especially we compared the MCV effect of different concentrations of 3 EDTA anticoagulants on the bias with time and instrument. Some results are gotten. In our results, K_(3-)EDTA anticoagulant shows more satisfactory MCV value than K_(2) or Na_(2-)EDTA. On using concentration of EDTA, 1.5㎎ EDTA/㎖ of blood show more satisfactory MCV value than 7.5㎎ EDTA/㎖ of blood. However, the choice of anticoagulant may be dependant on the different instruments.

This paper presents a reliability-based topology optimization (RBTO) using bi-directional evolutionary structural optimization (BESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. Deterministic topology optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, the RBTO can consider the uncertainty variables because it has the probabilistic constraints. In this paper, the reliability index approach (RIA) is adopted to evaluate the probabilistic constraint. RBTO based on BESO starting from various design domains produces a similar optimal topology each other. Numerical examples are presented to compare the DTO with the RBTO.

In patients with Cerebral vascular accident, Voiding Dysfunction is very usual, but if with no improvement for a long time, it can cause many complexed-problems as urinarytract injury, infection or inflamation and patients suffering from pain, inconvenience and anxiety. In this case 58-year-old female with Voiding Dysfunction with Neurogenic Bladder after Cerebellum Hemorrhage, for 6 monts there was no interval change on symptom, We prescribed appropeiate herbal medication, and perform acupuncture and moxa. 5 days later after admission in Taejeon Oriental Hospital, The patien was able to have self-voiding and gradually improved. So we report it for the better treatment.

This research presents a Reliability-Based Topology Optimization (RBTO) using Bi-directional Evolutionary Structural Optimization (BESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. Deterministic Topology Optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, RBTO involves evaluation of probabilistic constraints, which can be done in two different ways, the reliability index approach (RIA) and the performance measure approach (PMA). The reliability index approach (RIA) and the performance measure approach (PMA) are adopted to evaluate the probabilistic constraints. In order to apply the BESO method to the RBTO, sensitivity number is defined as the change in the reliability index due to the addition or the removal of the ith element. In the BESO, a mesh-independency filter using nodal variables is used to remove the checkerboard patterns. The optimal topologies of RIA and PMA are obtained very similarly. It is shown that RBTO based on BESO can be effectively applied from the presented examples.

Supra Pubic Catheter를 施行한 腦卒中 患者 1例에 對한 證例報告

유병찬,오병렬,김민상,안정조,임승민,최영,설인찬 대전대학교 한방병원 2002 惠和醫學 Vol.11 No.1

According to the literary study on catheterization of bladder in one case of patient with C.V.A. who was treated by supra pubic catheterization, the results were as follows. 1. If not immediately treat ischuria, emergency disease, very great danger to life can happen by loss of kidney function. So we must treat ischuria instantly by consideration of treatment from the factor. 2. Catheterization of bladder generally acted in emergency room, is emergency treatment only in the lower part of urethral obstruction. 3. Catheterization of bladder was put on record in Son Saimiao's Qianjinyaofang, which is the first book on it. It had been developed by Luo Qianyi, Zhang Jiepin, and Wang Dao. 4. Ancient times, an urethral catheter was made of green onion leaf, pig bladder, goose feather and so on. 5. Nelaton is catheterization of bladder in functional or momentary ischuria. Indwelling catheterization is treatment keeping in urethral canal for a long time. 6. Supra pubic catheterization is a surgical operating catheterization when urethral catheterization is impossible, is very easy and can decrease risk of infection. 7. After catheterization, for decreasing risk of the infection, a complication of catheterization, it is must be taken precedence, ascetic treatment, constantly management and sterilization, anti-biotic medication. 8. At times, increasing patient of emergency disease, as C.V.A etc., the needing of catheterization of bladder is increasing also for preventing infection and bed sore by ischuria and incontinence of urine. Therefore a specialty knowledge and skill about it is necessary.

교정용 미니 임플랜트 고정원과 SWA en masse sliding retraction 시 전치부 치축 조절 요인에 관한 유한요소해석

정혜심,성상진,문윤식,조영수,임승민 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.5

교정용 미니 임플랜트 고정원을 이용한 교정 치료가 보편화되며, SWA와 이를 이용한 en masse sliding retraction은 임상에서 흔히 사용하는 치료법이 되었다. 그러나 고정원을 성공적으로 보존하려는 노력에 비해, 발치 공간 폐쇄 시 전치부 치축 조절에 관여하는 요인에 대한 보고는 아직까지 부족한 실정이다. 본 연구에서는 제1소구치를 제거한 상악 치아와 치주 인대 그리고 치조골에 대한 3차원 유한요소 기준모델을 제작하였고, 제1대구치와 제2소구치 사이 주호선 10 mm 상방에 식립된 교정용 미니 임플랜트를 고정원으로 사용할 경우, 측절치-견치 사이의 견인 훅의 높이를 변화시키며 후상방 견인력을 가하거나, 주호선에 보상 만곡을 부여하는 것이 전치부 치축 조절에 어떤 영향을 미치는지 시뮬레이션 하였다. 또한 전치부 치축이 설측 경사된 모델을 같은 실험 조건으로 시뮬레이션 하여 발치 공간 폐쇄 시 설측 경사된 전치부 치축을 유지하거나 개선할 수 있는 요인을 검토하였고, 다음과 같은 연구 결과를 얻었다. 2 mm 높이의 견인 훅에 대하여 후상방으로 견인력을 가할 경우 발생하는 함입력으로 인하여 전치부 설측 경사가 더 감소되지는 않았다. 견인 훅의 높이가 5 mm인 경우 후상방 견인력을 가하면, 측절치의 치관 순측 및 치근 설측 이동이 일어나고, 견치의 비조절성 후방 경사 이동이 심화되었다. 4 mm의 보상 만곡은 측절치의 치관 순측 및 치근 설측 이동을 일으키고, 견치의 비조절성 후방 경사 이동을 감소시켰다. 또한 전치부가 설측 경사된 모델을 기준모델과 같은 실험 조건으로 시뮬레이션 한 경우 치근면의 응력 분포와 25000배 확대된 그래프 상에서의 치아 이동 양상은 매우 유사하였다. 이상의 결과는 미니 임플랜트-SWA sliding 생역학을 구사 시 견인 훅의 위치와 와이어 상의 보상 만곡의 유무에 의해 전치부의 치축 조절이 달라지며 실제 임상에서 가이드라인으로 활용될 수 있을 것이다. Objective: With development of the skeletal anchorage system, orthodontic mini-implant (OMI) assisted en masse sliding retraction has become part of general orthodontic treatment. But compared to the emphasis on successful anchorage preparation, the control of anterior teeth axis has not been emphasized enough. Methods: A 3-D finite element Base model of maxillary dental arch and a Lingual tipping model with lingually inclined anterior teeth were constructed. To evaluate factors influencing the axis of anterior teeth when OMI was used as anchorage, models were simulated with 2 mm or 5 mm retraction hooks and/or by the addition of 4 mm of compensating curve (CC) on the main archwire. The stress distribution on the roots and a 25000 times enlarged axis graph were evaluated. Results: Intrusive component of retraction force directed postero-superiorly from the 2 mm height hook did not reduce the lingual tipping of anterior teeth. When hook height was increased to 5 mm, lateral incisor showed crown-labial and root-lingual torque and uncontrolled tipping of the canine was increased. 4 mm of CC added to the main archwire also induced crown-labial and root-lingual torque of the lateral incisor but uncontrolled tipping of the canine was decreased. Lingual tipping model showed very similar results compared with the Base model. Conclusion: The results of this study showed that height of the hook and compensating curve on the main archwire can influence the axis of anterior teeth. These data can be used as guidelines for clinical application.
