Fractal mathematics is being highlighted as a research method for classification of image. But the application of Fractal dimension(FD) has been requited the complicated calculation method because of its complex repetition progressing. In this paper, it has been developed the new approach method to express the Fractal Dimension(FD) for aging level calculation and estimation system of outside insulator using special image processing algorithm. As a result after FD testing, the recognized aging estimation of FD has a very characteristics compared to the conventional visual inspection.

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsybefore radical prostatectomy. The aim of our study was to evaluate whether the intervalfrom prostate biopsy to radical prostatectomy affects immediate operative outcomes, witha focus on differences in surgical approach. The study population of 1,848 radicalprostatectomy patients was divided into two groups according to the surgical approach:open or minimally invasive. Open group included perineal and retropubic approach, andminimally invasive group included laparoscopic and robotic approach. The cut-off of thebiopsy-to-surgery interval was 4 weeks. Positive surgical margin status, operative time andestimated blood loss were evaluated as endpoint parameters. In the open group, therewere significant differences in operative time and estimated blood loss between the< 4-week and ≥ 4-week interval subgroups, but there was no difference in positivemargin rate. In the minimally invasive group, there were no differences in the threeoutcome parameters between the two subgroups. Multivariate analysis revealed that thebiopsy-to-surgery interval was not a significant factor affecting immediate operativeoutcomes in both open and minimally invasive groups, with the exception of the interval< 4 weeks as a significant factor decreasing operative time in the minimally invasive group. In conclusion, performing open or minimally invasive radical prostatectomy within 4 weeksof prostate biopsy is feasible for both approaches, and is even beneficial for minimallyinvasive radical prostatectomy to reduce operative time.

Objective:This study was conducted to assess the efficacy and safety of endovascular mechanical thrombectomy (EMT) for patients diagnosed with basilar artery (BA) occlusion. Materials and Methods : We retrospectively analyzed clinical and imaging data of 16 patients diagnosed with BA occlusion who were treated with endovascular intervention from July 2012 to February 2013. Direct suction using the Penumbra system and thrombus retrieval by the Solitaire stent were the main endovascular techniques used to restore BA flow. The outcomes were evaluated based on rate of angiographic recanalization, rate of improvement of National Institutes of Health Stroke Scale (NIHSS) score, rate of modified Rankin Scale (mRS) at discharge and after 3 months, and rate of cerebral hemorrhagic complications. Successful recanalization was defined as achieving Thrombolysis In Cerebral Infarction (TICI) of II or III. Results : Sixteen patients received thrombectomy. The mean age was 67.8 ± 11 years and the mean NIHSS score was 12.3 ± 8.2. Eight patients treated within 6 hours of symptom onset were grouped as A and the other 8 patients treated beyond 6 hours (range, 6-120) were grouped as B. Successful recanalization was met in six patients (75%) for group A and 7 (87.5%) for group B. Favorable outcome occurred in 4 patients (50%) for group A and 5 (62.5%) for group B. Conclusion : Our study supports the effectiveness and safety of endovascular mechanical thrombectomy in treating BA occlusion even 6 hours after symptom onset.

현재 우리 미술계는 매우 착종된 쉽게 해결 될 수 없는 성질의 상반된 두가지 흐름에 의해서 규정되고 있다. 현실에 실재하는 우토피로 맹신해왔던 공산주의 사회체제의 붕괴라는 세기적인 정치적, 사회적 지각변동 이후, 자신들의 창작행위를 사회주의 사회라는 우토피에로의 정치적, 사회적 변혁과정 가운데서 필연적으로 요구되는 실천행위으로서 이해함으로서, 자신들의 작업의 존재근거와 정당성이 예술외적 역사철학적 가정 가운데 선험적으로 확보되어 있다고 믿던 모더니즘이 전면적 위기에 봉착하고, 괴멸적인 방향상실을 겪는데서 비롯해 오는 깊은 침체의 늪에서 허우적거리고 있는 반면 또 한편으로는 예술의 모든 외적 및 내적 제약으로부터의 해방을 극한에까지 추구함으로서 얻어진 극단적인 예술의 자율화(Frenc feher)의 결과로서의 Postmodernism은, 더 이상 자신이 그것으로부터 해방되어야만 한다고 생각하는 관습적 형식이나 가치, 규범을 갖지 못하며, 결과 anything goes라는 규범의 완전한 상실과 공백의 상태를 가져온다.
