SHAP를 이용한 이미지 어노테이션 자동화 프로세스 연구
정진형,심현수,김용수 한국산업경영시스템학회 2023 한국산업경영시스템학회지 Vol.46 No.1
Recently, the development of computer vision with deep learning has made object detection using images applicable to diverse fields, such as medical care, manufacturing, and transportation. The manufacturing industry is saving time and money by apply- ing computer vision technology to detect defects or issues that may occur during the manufacturing and inspection process. Annotations of collected images and their location information are required for computer vision technology. However, manually labeling large amounts of images is time-consuming, expensive, and can vary among workers, which may affect annotation qual- ity and cause inaccurate performance. This paper proposes a process that can automatically collect annotations and location in- formation for images using eXplainable AI, without manual annotation. If applied to the manufacturing industry, this process is thought to save the time and cost required for image annotation collection and collect relatively high-quality annotation information.

'쇠고기 이력추적제' 6월 22일 실시 어떻게 준비하고 관리해야 하나
정진형,Jeong, Jin-Hyeong 축산물품질평가원 2009 KAPE누리 Vol.153 No.-
5월은 본 사업을 앞두고 있는 중요한 시기로써 그동안 추진해온 시범사업의 문제점을 보완하고 전면사업 착수에 연착륙을 위한 준비 작업에 박차를 가하고 있다. 하지만 그동안 시범사업에 참여하여 동 제도를 잘 알고 있거나, 본 사업이 시작되면 처음으로 동 업무를 해야 하는 분들 등, 사업 참여자들이 여러 부류로 나뉘어져 있어 동 사업의 본격시행을 앞두고 독자들의 올바른 이해를 도기 위해 이력추적제 단계별로 어떻게 업무가 진행되고 무엇을 사전 준비해야하는 지를 알아본다.

This study has been done to prove that keratinized gingiva is required for the periodontal health and to analyse the adequate width that is necessary. Until now, the study on frenum has been documented on changing its location. But the location or the formation of the frenum has not been reported. This experiment has used 173 patients from the department of periodontology of Dankook University to investigate the width of keratinized gingiva, the formation of the frenum and its location for the frequency. This study also looks into the relationship between the gingival recession and the structure of the frenum, and affects they have on periodontal health. The width of the keratinized gingiva in the mandible has been found to be highest in the lateral incisor than in the central incisor. The width decreased from the canine to the first premolar until it reached the molar. The interproximal area of the mandibular frenum was 77.9%, which was greater than the frequency (22.1%) from the midline of the teeth. The highest frequency of frenum was at 30.6% in between the both central incisor then second greatest at 20.6% in between the right canine and the right first premolar. Frenum was not found in between the second premolar and the distal area. In the morphology of the frenum, it was found that 43.4% out of 551 parts were found to be a single narrow frenum, and the double or triple ligamented form of the complex frenum were found in similar frequency of 237 parts, but the broad frenum was rarely frequent. The incisal area was popular mostly with the single narrow frenum, the left premolar area frequented 57.4%, and the right premolar frequented 64.7%. Because the distance between the frenum apex and the gingival margin measured to be about 5mm or greater, the frenum apex started in the mucogingival junction and not just below the keratinized gingiva. In the 551 area investigated, 48.3% of gingiva showed recession, incisal area had recession the least at 44.9%, right buccal side at 47.4%, and right buccal side frequented the highest at 52.1%. The teeth that showed recession recessed at the average of 2.151.0.mm and the left canine showed the greatest amount of gingival recession. In the investigation to find out if the keratinized gingiva and the gingiva recession had mutually related somehow, the width of keratinized gingiva showed no affect on the probing depth, but had affected in the gingiva recession. This investigation showed that the gingival recession and the morphology of the frenum related in that, the single narrow frenum had recessed the least and the broad frenum recessed the most. With this analysis, a conclusion was drawn that the morphology of the frenum had affected in the gingical recession.
