A Two Layered Approach for Animation Sketching
Sohn, Ei-Sung,Jeon, Jae-Woong,Park, Tae-Jin,Sohn, Won-Sung,Lim, Soon-Bum,Choy, Yoon-Chul Korea Multimedia Society 2009 멀티미디어학회논문지 Vol.12 No.12
In this paper, we present an animation sketching system using a two layered approach. Animation sketching is a popular technique to create informal animations but it is often suffered by the low-quality output due to a trade-off between convenience and complexity. Our aim is to support sketching practical animation scenes easily and fast while not complicating the simple sketching interface. The key idea is to combine two conceptual stop motion layers, a whiteboard and cutout animation layer, in a seamless interface. As a background, the whiteboard animation layer handles stroke-oriented objects, while the cutout animation layer takes charge of transform-oriented objects. We found that this approach enables users to express more complicated animation fast while still maintaining a concise sketching interface. We demonstrate the usability and flexibility through resulting animations from user experiments.

Aims: Simple sugar is spotlighted as an important causative factor of diabetes, hypertension, and other metabolic disease. But the rela- tion between consumption of simple sugar/fructose and non-alcoholic fatty liver disease (NAFLD) was inconclusive in recent two systematic reviews. So, we study the association of consumption level of simple sugar with aminotransferase activity and fatty liver in Korean. Methods: Four hundred two subjects were enrolled this study from health promotion center. 119 subjects were diagnosed by NAFLD, and 282 subjects were control. All NAFLD patients were diagnosed by ultrasonography within 3 months, alcohol consumption below 140 g/week (male), 70 g/week (female). Who have diabetes, viral hepatitis, other liver disease or metabolic disorders are excluded. Amount of simple sugar intake was assessed by validated questionnaire from Korea Food and Drug Administration. Results: Total simple sugar slightly high, but not significant between sonographic fatty liver and control group in men (43.63 ± 25.92 vs. 41.73 ± 30.89, p>0.05) and women (46.45 ± 28.93 vs. 42.30 ± 29.42, p>0.05). When the amount of simple sugar divided three groups and adjusted with age and body mass index, lower one third sugar intake group decreased risk of abnormal liver function up to 96% in men ( p for trend = 0.02). And lower one third sugar intake group decreased risk of abnormal liver function up to 65% in women (p for trend = 0.004). Middle one third intake group decreased risk of abnormal liver function up to 53%, 64% in men and women respectively.(p for trend = 0.002, 0.004 respectively). But amount of simple intake did not show any correlation with prevalence of NAFLD. Only amount of carbohydrate showed positive correlation with prevalence of NAFLD in men and women. Conclusions: Prevalence of abnormal ALT level was higher in high simple sugar intake group compare to low simple sugar group. But there is no association of the simple sugar and prevalence of NAFLD.

Pulmonary thromboembolism (PTE) increases the pressure of the right ventricle and leads to symptoms and signs, such as dyspnea and hypoxia. If PTE causes hemodynamic instability, thrombolytic therapy should be considered. A mechanical thrombectomy is an alternative treatment to thrombolytic therapy and should be considered when thrombolytic therapy is contraindicated. Various devices are used in mechanical maceration and catheter-directed thrombolysis, but there is no standard mechanical device for PTE as yet. We report here on 2 clinical experiences of mechanical thrombectomy using the Arrow-Trerotola percutaneous thrombolytic device to remove residual clots after systemic thrombolysis in patients with massive PTE.
