For treatment of partially edentulous patients, a treatment using implant is widely used. Treatment method using implant are implant fixed prostheses and removable partial dentures, and for patients with severe bone resorption, removable implant overdenture with the effects of aesthetic and reducing cost can be used as treatment options. Specially, prosthesis with milled-bar and attachment has the effect of being splinted between implant fixtures, higher retention and stability than conventional removable partial denture. And it has the effect of improvement of aesthetic through lip support by denture base. In this case, the patient with severe alveolar bone resorption and partial edentulous maxilla and mandible was treated by implant-assisted removable partial denture using Milled-bar and ADD-TOC attachment. The esthetic was improved by removing the clasp because of effects of additional retention by using the attachment, and reducing palatal coverage of implant-assisted removable partial denture. The clinical results were satisfactory on the aspect of aesthetic and masticatory function.

본 논문에서는 스테레오 영상 인식에 기반한 직육면체형 물체의 부피를 계측하는 한 방법이 제안된다. 제안된 방범은 두 대의 CCD(charge coupled device)카메라로부터 획득된 영상에 대하여 관심영역추출, 특징 추출, 그리고 스테레오 정합에 기반한 꼭지점 인식의 과정을 통하여 3D 물체의 부피를 계측한다. 제안된 방법은 3D 물체의 특징을 나타내는 꼭지점 후보들을 영상처리과정을 통해 추출한 후, 이들 꼭지점들에 대해서만 스테레오 정합을 수행함으로써 고속의 부피 계측이 가능한 이점이 있다. 실험을 통하여, 본 논문에서 제안한 방법이 직육면체형 물체의 고속 부피계측에 효과적으로 사용될 수 있음이 보여진다. In this paper, we propose a stereo image recognition-based method for measuring the volume of the rectangular parallelepiped. The method measures the volume from two images captured with two CCD (charge coupled device) cameras by sequential processes such as ROI (region of interest) extraction, feature extraction, and stereo matching-based vortex recognition. The proposed method makes it possible to measure the volume of the 3D object at high speed because only a few features are used in the process of stereo matching. From experimental results, it is demonstrated that this method is very effective for measuring the volume of the rectangular parallelepiped at high speed.

The persistence pattern of thiacloprid and flufenoxuron were determined in strawberry with calyx using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The study was carried out to propose import tolerance using OECD maximum residue limit (MRL) calculator for export promotion of strawberry with calyx to Taiwan. The residue trials of thiacloprid (10% SC) and flufenoxuron (5% DC) were conducted as decline tests at three independent sites for strawberry. Excellent linearity observed for all of the analytes with determination coefficient (R<sup>2</sup>)≥0.99. The both LOQ (limit of quantification) of thiacloprid and flufenoxuron were 0.01 mg/kg in strawberry. The recovery rate of thiacloprid presented 76.8∼ 101.4 % in site 1, 83.9 ∼108.6 % in site 2 and 76.1∼101.9 % in site 3, respectively. The recovery rate of flufenoxuron showed 80.2∼98.7 % in site 1, 99.8∼117.4 % in site 2 and 81.1∼ 91.7 % in site 3, respectively. The residual amount of thiacloprid in the strawberry for three decline test were found in the range of 0.44 to 1.11 mg/kg in site 1 (Sacheon), 0.17 to 0.38 mg/kg in site 2 (Gokseong) and 0.19 to 0.39 mg/kg in site 3 (Nonsan). The residual amount of flufenoxuron in the strawberry for three decline test were found in the range of 0.34 to 1.50 mg/kg in site 1 (Sacheon), 0.20 to 0.48 mg/kg in site 2 (Gokseong) and 0.28 to 0.58 mg/kg in site 3 (Nonsan). In conclusion, the both import tolerance for thiacloprid and flufenoxuron in strawberry with calyx were proposed to 2.0 mg/kg in Taiwan.

Pre-harvest interval and decline pattern of flonicamid, TFNG and TFNA were determined in strawberry with calyx using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The study was carried out to propose import tolerance for export promotion of strawberry to Taiwan by using OECD maximum residue limit (MRL) calculator. The residue field trials for flonicamid (50%, SG, insecticide) were carried out as decline tests in the three independent sites to cultivate strawberry. The flonicamid (50%, SG) of test substance was diluted 10,000 times and the 0.00764 kg a.i./10 a of flonicamid 50% SG was applied for the sites two times at 7-day intervals. Sampling was carried out 0, 1, 3, 5, 7, 14, 21, 28, 35 and 45 days after the final application of flonicamid (50%, SG), and untreated control samples were collected prior to the sampling of treated plots. The residual amount of flonicamid included with TFNG and TFNA presented 0.06∼1.40 mg/kg in site 1 (Sacheon), 0.06∼0.82 mg/kg in site 2 (Gokseong) and 0.18∼1.15 mg/kg in site 3 (Nonsan), respectively, in the strawberry with calyx for three decline test. In cThe import tolerance of flonicamid for strawberry with calyx may be recommended at 3.0 mg/kg in Taiwan by the OECD MRL calculator.

본 연구에서는 택배물의 분류를 위한 자동화 시스템에서 주소 영역 검출 알고리즘을 제안하였다. 주소 영역 검출을 위한 알고리즘에서는 대상 영상이 매우 크기 때문에 수행 시간의 단축을 위하여 택배 라벨부분을 포함하는 제한된 범위인 관심영역(Region of interesting: ROI)을 구한 후 관심 영역내에서 모든 알고리즘이 수행되도록 한다. 주소 영역 검출을 위하여 택배 라벨의 특징인 주소 영역을 둘러싸고 있는 테두리선을 이용한다. 이진화(thresholding) 과정과 라벨링 (Labeling) 과정을 통하여 획득된 영상에서 주소 영역의 테두리선과 그 밖의 성분들을 각각 독립된 연결성분들(connected components)로 검출한다. 주소 영역을 둘러싸는 테두리선의 기하학적인 특징을 이용하여 여러 개의 연결성분들 중에서 주소 영역을 둘러싸는 테두리선을 분리한다. 마지막으로 윈 영상과 분리된 테두리선 부분과의 논리적 곱을 이용하여 주소 영역을 최종적으로 검출하게 된다. In this paper, we proposed the algorithm for locating destination address block (DAB) from automatic system to classify packages. For locating DAB, because the size of obtained images is are very large, we select the region of interesting (ROI) to reduce time carrying into algorithm. After selecting the ROI, proposed algorithm is carried out within the ROI. We extract the outline of the handwriting part of the DAB and the rest components within the obtained ROI using thresholding. We carry out labeling to extract each connected component for extracted outline and the rest components. We extract the outline of the handwriting part of the DAB using the geometrical characteristic of the outline of the handwriting part of the DAB among many connected components. The last, we extract the locating DAB using the outline of the handwriting part of the DAB.
