Chassis system has a large influence on ride quality, stability and NVH performance of a car. To improve the performance and reduce cost, the development of chassis modular assemblies is emphasized. To develop chassis corner modules, it is necessary to predict the performance of full vehicle motion such as ride, handling performance, NVH characteristics and durability of modules. In this paper, full vehicle test is performed to acquire the road load data of chassis corner module of passenger car. 3-axis simulator modeling are carried out to simulate reaction force analysis and fatigue analysis of new developed modules. Also, real simulator tests to validate performance of new developed modules are performed. We had developed the accelerated durability test procedure of KATECH PG and it is used to test chassis corner modules at laboratory and simulate durability performance. All these results have been provided to module and parts company and make an important role to develop chassis corner modules.

Objectives : The aim of this study is to report the improved case of bilateral avascular necrosis(AVN) of femur head treated with Korean medicine and Fascia Chuna Therapy Methods : The patient diagnosed with bilateral AVN is hospitalized at department of korean rehabilitation medicine, Samse hospital of korean medicine. The subject is treated by herbal medicine, acupuncture, SBV and hip joint gyoung-geon chuna. This study was measured by visual analogue scale(VAS) score, walking time without pain per 6 minutes and harris hip score(HHS). Results : The patient showed decreased VAS score, HHS and improved walking time without pain per 6 minutes after treated with korean medicine and hip joint Fascia Chuna Therapy. Conclusions : The patient showed reduced pain and positive effect on activities of daily living.

Microcomputed tomography (MCT) made it possible to investigate the morphology of root canals more accurate. The aim of this study was to compare the effects of four root canal shaping methods, the profile system, the ProTaper system, a combination of these, and stainless steel K-files, in the shaping of the mesial root canals of extracted human mandibular first molars, three-dimensionally using MCT. Eight extracted mandibular first molars were scannde using MTC before and after the root cannals were instrumented. Two specimens were prepared using the Profile system and another two specimens were prepared using MCT before and after the root cannals were instrumented. Two specimens were prepared using the Profile system and another two specimens were prepared using the ProTaper system according to manufactures recommendation.(omitted)

라벨인식과 같은 광학 문자 인식은 영상처리를 활용한 컴퓨터 비전의 대표적인 연구분야이다. 본 연구에서는 딥러닝 기반의 라벨인식 시스템을 고안하였다, 생산 라인에 적용되는 라벨인식 시스템은 인식 속도가 중요하기 때문에 기존의 R-CNN기반의 딥러닝 신경망보다 월등히 빠른 오브젝트 검출 시스템 YOLO를 활용하여 문자를 학습 및 인식 시스템을 개발하였다. 본 시스템은 기존 시스템에 근접하는 문자인식 정확도를 제공하고 자동으로 문자영역을 검출 가능하며, 라벨의 인쇄불량을 판독하도록 하였다. 또한 개발, 배포, 적용이 한번에 가능한 프레임워크를 통하여 생산현장에서 발생하는 다양한 이미지 처리에 활용될 전망이다.

With the recent advances in technology, automatic speech recognition (ASR) has been widely used in real-world applications. The efficiency of converting large amounts of speech into text accurately with limited resources has become more vital than ever. In this study, we propose a method to rapidly recognize a large speech database via a transformer-based end-to-end model. Transformers have improved the state-of-the-art performance in many fields. However, they are not easy to use for long sequences. In this study, various techniques to accelerate the recognition of real-world speeches are proposed and tested, including decoding via multiple-utterance-batched beam search, detecting end of speech based on a connectionist temporal classification (CTC), restricting the CTC-prefix score, and splitting long speeches into short segments. Experiments are conducted with the Librispeech dataset and the real-world Korean ASR tasks to verify the proposed methods. From the experiments, the proposed system can convert 8 h of speeches spoken at real-world meetings into text in less than 3 min with a 10.73% character error rate, which is 27.1% relatively lower than that of conventional systems.

코로나로 인해 비대면 생활이 지속되면서, 사람들은 실외 운동 및 만남 장소로 한강과 같이 탁 트인 야외를 찾고 있다. 이는 MZ 세대들의 건강과 몸매 가꾸기 등 자기관리에 대한 관심이 증가하는 트렌드와 시너지 효과를 내고 있다. 이러한 현상은 등산, 바디프로필, 필라테스, 헬스, 홈 트레이닝 등 운동에 대한 활동의 비약적 증가로 이어진다. 본 연구에서는 위의 두 가지 트렌드 흐름을 기반으로, 러닝을 시작하고 싶은 초보자들이 한강 공원에서 가볍게 시작할 수 있도록 하는 모바일 운동 앱인 'OnTheRiver'를 설계 및 구현하게 되었다.
