  • In this paper, an integration framework of Geometric Constraint Solving Engine and AutoCAD is presented, and a dynamic geometric constraint system is introduced. According to inherent orientation features of geometric entities and various Object Snap results of AutoCAD, the' proposed system can automatically construct an under-constrained geometric constraint model during interactive drawing. And then the directed constraint graph in a geometric constraint model is realtime modified in order to produce an optimal constraint solving sequence. Due to the open object-oriented characteristics of AutoCAD, a set of user-defined entities including basic geometric elements and graphics constraint relations are defined through derivation. And the custom-made Object Reactor and Command Reactor are also constructed. Several powerful characteristics are achieved based on these user-defined entities and reactors, including synchronously processing geometric constraint information while saving and opening DWG files, visual constraint relations, and full adaptability to Undo/Redo operations. These characteristics of the proposed system can help the designers more easily manage geometric entities and constraint relations between them.

  • It is generally required to use modeling or animation tools for inserting dynamic objects into augmented reality, and this process demands high expertise and complexity. This paper proposes a video object based authoring method that enables augmentation with dynamic video objects without such process. Integrated grab-cut and grow-cut method strips initial area of video target off the existing video clips, and snap-cut method is then applied to track objects' boundaries over frames so as to augment real world with continuous motion frames. Experiment shows video cut-out and authoring results achieved by only a few menu selections and simple correcting sketch.

  • The object of the present study was to compare abnormal serum canine pancreas-specific lipase results and pancreatic ultrasonographic findings in dogs with pancreatitis. Pancreatitis is a common disease in dogs that is difficult to diagnose. The noninvasive diagnostic procedures, including a serum canine pancreatic-specific lipase (cPL) test and ultrasonographic changes in the pancreas, can be considered for the diagnosis of canine pancreatitis in clinical practice. A retrospective study was performed to assess pancreatitis in dogs. Forty client-owned dogs were suspected to have pancreatitis, which was confirmed by abnormal serum SNAP cPL results. Abdominal ultrasound examinations were also performed. The present study investigated the distribution of clinical signs associated with pancreatitis, and the dogs were divided into two groups: group 1 (clinical signs compatible with pancreatitis; n = 30) and group 2 (no clinical signs; n = 10). Based on this study, an abnormal result on the SNAP cPL assay can still present as a normal pancreas through an ultrasonographic examination, and a normal health status can identify the status of pancreatic ultrasonographic abnormal lesions. Therefore, for dogs with suspected pancreatitis, it is important to repeat an ultrasonographic evaluation. There is no significant difference between clinical symptoms and ultrasonographic changes in the pancreas.

  • The current study is the first paper on FPT(failure of passive transfer) of horse population in Korea. The object of this study was to comparison of immune status normal and patient horses. Failure of passive transfer is the most common immunodeficiency disorder of horses. Twenty-two foals and 18 horses from Jeju of the equine hospital were diagnosed with the SNAP Foal IgG Test Kit. All adult horses had normal immune functions (≥800 mg/dl). Thirteen of the 22 newborn babies (59%; ∠800 mg/dl) had a weak immune function but recovered and survived after treatment. Nine of these 22 are horses with strong immunity (≥800 mg/dl), indicating that high IgG concentrations in the blood can cause infectious diseases. There were a total of six dead, four of which were infectious diseases. In addition, early identification of infectious diseases in newborn foals is expected to help prepare systematic health management measures for the development of the disease.

  • The main object of this study is to develop a reliable FEM simulation technique for stability test using ABAQUS software and to clarify the effect of base profile of a steel D&I(drawn and ironed) can on the dome reversal pressure. For the can after body making simulation, two kind of stability test, dome buckle test and axial crush test are performed. The factors studied in the base profile on the dome reversal pressure are the base diameter, the rim radius, the dome shoulder radius, the dome radius and the dome depth. Within the limits before the occurrence of normal snap-through buckling of dome, the dome reversal pressure is improved by decreasing the base diameter, increasing the dome depth or increasing the dome shoulder depth.
