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.

Five adults (3 cases of bilateral posterior crossbite, 2 cases of unilateral posterior crossbite) with intermaxillary discrepancy of over 5㎜ due to maxillary transverse deficiency were treated by surgically assisted rapid maxillary expansion (SARME). Bilateral maxillary horizontal osteotomies, osteotomies of pterygomaxillary junction and anterior lateral nasal wall, ans anterior palatal osteotomy were performed in 4 cases, and unilateral osteotomies in 1case, followed by palatal expansion with tooth-borne orthopedic applicance. No significant complication was observed. The mean palatal expansion was 7.2㎜ (5.8∼10.0㎜) in the maxillary first molar region. During the mean follow-up period of 4 years (5 months∼8 years 7 months), no recurrence of crossbite was observed in all cases. The SARME seemed to be a simple, stable, and reliable procedure for achieving a permanent increase of over 5㎜ in skeletal maxillary transverse width of adults.

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.

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.
