In a case of driving beginnners, it is very difficult to park a car perfectly because driver's knowledge makes more errors than intelligent mechanism when they are performed repeatedly. However skilled drivers be of experienced knowledge are able to park a car quickly. In this paper, we analyzed driving patterns of skilled drivers, designed the fuzzy controller to park based on it, and perform auto-parking simulation of a car using that controller.

The purpose of this study is to propose the renal housing policy direction for undergraduates based on their actual rental housing conditions and needs who reside in non capital area. For the study, questionnaires were answered by 315 undergraduates of 3 universities who reside in rental housings in Cheongju-city. Major findings were as follows: (1) Most of undergraduate rental housings had the size from 12㎡ to 29㎡ and from 29㎡ to 41㎡, were multi-household studio type with room+bath+kitchen, and were typically monthly rent payment. (2) The needs of rental housings were the same as present residence. The possible monthly rent were mostly 300 thousand won, and the most preferred distance was under 10 minute walk from university. The assistance policy that undergraduates need was firstly the central/local governments' refurbished housing supply near university with low rent, and then deposited housing supply for undergraduates by LH corporation.

호흡기 증상과 급성신부전증이 발생된 환자에서 혈액검사, 혈청학적 검사, 방사선학적 검사, ANCA test 및 신생검을 통하여 Wegener씨 육아종증을 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 본질환이 재발하는 경우는 cyclophosphamide에서 azathioprine으로 치료약을 바꾸었을때나 특히 ANCA 반응이 양성으로 지속시 발생한다. Godman과 Churg는 상기도의 괴사성 육아성 병변, 하기도의 괴사성 혈관염, 국한성 신사구체염을 진단의 지표로 삼았다. 특히 상기도 점막의 생검 소견상 괴사성 육아성 혈관염이 보이면 일단 본 증을 의심하고 폐 생검과 신 생검이 필요로 한다. Wegener's Granulomatosis is an uncommon disease which is characterized by granulomatous vasculitis of both lung and kidney. Although the cause is unknown, it's suggesting that disordered immunity with both antibody and cell-mediated tissue damage occurs. The disease affects patients of any age. Characteristic clinical manifestations are diverse but in clude saddle nose deformity, sinusitis, productive coughing, myalgia, fever etc. Characteristic laboratory abnormalities include elevated ESR, neutrophilic leukocytosis, anemia and positive test for ANCA test. Renal biopsy is important for diagnosis. The treatment of choice is a combination of corticosteroid and cytotoxic agent. A53-year-old woman was admitted to our hospital because of productive coughing, short of breathing, oliguria, nausea, and vomiting. Three months ago, she was suffered from general weakness, poor appetite, tingling sensation on extremity, and loosely stool. Twenty days ago, above symptoms were aggravated, she admitted local clinic. Six days ago, because of CBC showed anemia , she was done transfusion. During transfusion, she was developed urticaha then productive coughing, dyspnea, increased serum BUN and creatinine levels. She was transferred to our hospital under the impression of ARF. On the admission, she was chronic ill-looking appearance with pale conjunctiva, tachypnea, dyspnea, and cold sweating. We have checked the patient by CBC, serum and serologic test, X-ray, ANCA test, renal biopsy. With renal biopsy microscopic examination study revealed necrotizing vasculitis, We treated a combination therapy with methyl-PDS and cyclophosphamide. She had a good response. So we report wegener's granulomatosis with the review of relevant literature.

박종익,이현정,고효정 大韓神經精神醫學會 2004 신경정신의학 Vol.43 No.5

Objectives : To demonstrate consistent and significant findings of neurocognitive functioning in detoxified alcoholics have been inconclusive. The purpose of this study was to evaluate cognitive functions in detoxified alcoholics and the relationship between neuropsychological test scores and alcohol consumption patterns. Methods : Twenty-four alcoholics, aging between 30 and 50 years, at least 4 weeks after the beginning of detoxification and 24 normal controls equated for age and education were exmained on Seoul computerized neurocognitive function tests in order to evaluate neurocognitive functions, which include attention, memory function, executive function, motor performance. Results : Compared to controls, alcoholics were more impaired on both finger tapping test (FTT, right : p<0.05, left : p<0.01), but there were no significant differences between two groups on any measures including attention, memory function, and executive function. Even though there were significantly negative associations between length of drinking history and performances on FTT with both hands (right : r=-0.55, p<0.01 ; left : r=-0.48, p<0.05) in alcohol group, multiple regression analyses showed that age and STAI contributed significantly to the prediction of FTT, ameliorating the dignostic effect. Conclusion : There was no evidence of significant declines in attention, memory, and executive functions in alcoholics compared to normal controls, except impaired motor performance functions which may be related to concurrent anxiety.

박양수,김종철,황현식 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.3

본 연구는 Ⅲ급 부정교합자에서 중심교합상태의 두부 방사선 사진과 MPI 수치를 이용하여 중심위로 전환한 두부 방사선 사진(Centrically related cephalometrics)를 계측하여 중심위 변위시 유의한 계측치 변화가 있는지 확인하고자 시행되었다. 교정치료의 경험이 없는 25명의 Ⅲ급 부정교합군과 25명의 정상교합군을 대상으로 하여, 중심교합위 상태의 측모 두부 방사선 사진과 중심위 및 중심교합위 기록을 채득하고, 모형을 SAMⅡ 교합기에 부착하였다. 중심위 변위량은 MPI(Mandibular Position Indicator)를 이용하여 계측하였으며, MPI 수치와 중심교합위 상태의 측모 두부 방사선 사진의 투사도를 이용하여 Conversion work sheet상에서 중심위 전환을 시행하였다. 두부 상사선 계측 항목은 하악골의 위치와 관계되는 것을 선택하였다. 정상교합군과 Ⅲ급 부정교합군에서 중심위와 중심교합위간의 계측치 변화를 연구하여 다음과 같은 결과를 얻었다. 1. 하악 과두에서의 중심위 변위량은 정상교합군에서 전후방 변위량(ΔX)0.56±0.50mm, 수직적 변위량(ΔZ) -0.61±0.53mm였으며, Ⅲ급 부정교합군에서 전후방 변위량 (ΔX) 0.093±0.77mm, 수직적 변위량(ΔZ) -0.64±0.89mm로, 두군 보두 후하방 변위양상을 나타냈다. Ⅲ급 부정교합군에서 정상교합군보다 전후방 변위량이 더 크게 나타났으나 통계학적인 유의성은 없었다. 2. 중심교합위와 중심위 두부 방사선 사진의 계측치를 비교해 본 결과 정상 교합군에서 ANB, Facial angle, Facial convexity, ODI 등의 항목이 유의한 차이를 나타냈다. Ⅲ급 부정 교합군에서는 ANB, Facial angle, facial convexity, ODI, SNB, APDI, L1-FP 등 유의한 차이를 보이는 항목이 더 많았고 유의성도 더 높게 나타났다. 3. 두부 방사선 사진의 계측치 변화는 중심위 변위와는 연관성이 있었으나, 정상교합군과 Ⅲ급 부정교합군에 대한 연관성이 없었다. 이상의 결과는 중심의 변위량이 임상적으로 재현할 수 있는 중심위 위치에서 정상적으로 변위되는 양보다 큰 경우 중심위는 교정 환자에서 적절한 진단과 치료 계획 수립을 위한 기준 점으로 고려되어야 함을 시사하였다. The purpose of this study was to investigate if there were a significant difference between cephalometric measurements of mandibular position derived from a centric occlusion tracing compared to those of a converted centric relation tracing in the Class Ⅲ malocclusion. The sample consisted of 25 ClassⅢ malocclusion and 25 normal occlusion persons who had no orthodontic treatment. The records included an lateral cephalometrics in centric occlusion, centric relation and centric occlusion bite registration and diagnostic casts mounted on the SAM Ⅱ articulator in CR. The amount of CR-CO discrepancy of condyle was recorded using a MPI(Mandibular Position Indicator, MPI 200, Great Lakes Orthodontics, USA). The conversion of the CO cephalogram to CR using the MPI readings was performed on the Conversion work sheet. Measures of mandibular position were chosen for the purpose of this study. The comparison of the difference between CO and CR cephalometric measurements in the normal occlusion and Class Ⅲ malocclusion group were studied. The results were as follows: 1. In the features of CR-CO discrepancy of the condyle, the condyle was displaced posterior and inferior when the teeth were in centric occlusion. The horizontal component(ΔX) in Class Ⅲ malocclusion group was greater than the vertical component(ΔX) and also greater than the horizontal component(ΔZ) in normal occlusion group. There was no statistically significant correlation between MPI measurements and the groups of normal occlusion and Class Ⅲ malocclusion group. 2. In the comparison of the cephalometric measurements in each group, Normal occlusion group showed significant difference in measurements such as ANB, Facial angle, Facial convexity and ODI. ClassⅢ malocclusion group showed significant difference in measurements such as ANB, Facial angle, Facial convexity, OEI, SNB, APDI, L1-FP and it had more significance than the normal occlusion group. 3. The Value of cephalometric measurements was significantly different between CO and CR but there were no differences between the groups of normal occlusion and Class Ⅲ malocclusion. The results of this study suggest that if the discrepancies are greater than the amount of normal displacement from clinically captured centric relation, centric relation should be considered as the starting point for proper diagnosis and treatment planning.
