대형 구조물에 주로 사용되는 고강도 콘크리트는 화재 시 폭렬이 발생하여 구조물의 심각한 손상을 초래한다. 최근 고강도 콘크리트의 폭렬현상을 감소시켜 구조물의 내화성능을 확보하기 위한 다양한 연구가 진행되고 있으며, 본 논문에서는 섬유를 혼입한 고강도 콘크리트에 대한 내화해석 모델을 제시하였다. 섬유의 거동 및 고온에서의 콘크리트 내부의 물리적인 현상을 고려하여 수정한 고강도 콘크리트의 재료모델을 섬유혼입 고강도 콘크리트의 재료모델로 선택하였다. 수정된 재료모델을 이용하여 얻은 섬유혼입 고강도 콘크리트의 내화해석 결과를 실험결과와 비교하였고, 섬유혼입 고강도 콘크리트 재료모델을 제안하였다. High strength concrete used for large structures is vulnerable to fire due to explosive spalling when it is heated. Recently, various research is conducted to enhance the fire-resistance of the high strength concrete by reducing the explosive spalling at the elevated temperature. In this study, a heat transfer analysis model is proposed for a fiber-embedded fire-resistant high strength concrete. The material model of the fire-resistant high strength concrete is selected from the calibrated material model of a high strength concrete incorporating thermal properties of fibers and physical behavior of internal concrete at the elevated temperature. By comparing the simulated results using the calibrated model with the experimental results, the heat transfer model of the fiber-embedded fire-resistant high strength concrete is proposed.

Objective: The aim of this study is to validate motion analysis technology using 3D depth camera for measurement in industrial field. Background: The importance of technology for measurement and analysis of work log is also increasing due to provide worker centered services in various industrial field. The work log measurement technologies’ trend has been changed to the contactless sensor type from existing contact type with wearable, because of usability. Method: In this study, we implemented to collect tasks’ motion data using 3D camera system (camera (N: 8), Vicon, Inc., UK) and depth camera of contactless type (Azure Kinect, Microsoft, Inc., USA). The main joint ((Lower body: Knee, Hip), (Upper limb: Elbow, Shoulder)) angle’s variable trend was compared in 5 tasks (① lifting, ② lowering, ③ pushing, ④ pulling, ⑤ hand operation(screwing)). Results: We compared result between the 3D motion capture system and contactless type’s depth camera. The main joint ((Lower body: Knee, Hip), (Upper limb: Elbow, Shoulder)) angle’s variable trend was compared in 5 tasks, and in the results, the similar angle variable tendency was shown in most joints. Due to the limitation of the depth camera capture range, measurements were performed for each basic motion. Conclusion: It is expected that various services such as customized work management and accident prediction, etc. will be possible through work log management. In the next study, we plan to develop variety of services based on this study.
A Study on the Accuracy Evaluation Method of Wearable Sensors
Young Sub Shin(신영섭),Jong Hyun Kim(김종현) 대한인간공학회 2021 대한인간공학회 학술대회논문집 Vol.2021 No.11
Objective: The aim of this study is to evaluate the knee angle variations` accuracy of wearable sensor through the entire interval tendency analysis. Background: The previous studies on evaluating the accuracy of wearable sensors mainly used maximum, minimum and mean values for evaluation. Since the maximum and mean values can only evaluate the accuracy of a particular interval or a single frame of measured data, the evaluation of the accuracy and tendency for the entire interval showed limitations. Data on the entire interval tendency are critical in areas such as healthcare, recuperation, and exercise to assess the current state of the subject. Method: Two wearable sensors (Ebernean, Korea) located in the tibia and femur and an optical 3D motion capture system (Vicon, INC, UK) were used for data acquisition. The knee flexion-extension was repeated five times in the lying position, and for synchronization of the wearable sensor data with the 3D motion capture system, up-sampled at 100 Hz based on the peak flexion angle. The absolute error values of the peak flexion angle and the RMSE of the entire interval angle were derived. In order to verify the reliability of wearable sensors, the interclass correlation coefficient(ICC) was analyzed. Results: The comparison value between wearable sensor and the 3D motion capture system showed that the ICC(2.1) value was 0.98(p=0.00). The peak flexion angle of mean absolute error was 2.34° (±2.0), and the entire interval angle of mean absoulte error was 8.72° (±3.41). Conclusion/Application: The accuracy of wearable sensors was high in verification with peak flexion angle, but lower in verification with entire interval angle comparison. In the results of this study, it is expected that the verification method through the entire interval tendency data can be utilized importantly in the verification of accuracy of wearable sensors.

본 연구는 주기적인 강제 진동이 가해지는 액적의 모드 특성을 실험적으로 이해하는 것을 목적으로 하고 있다. 액적의 공진 주파수 예측을 수행하여 이론 및 실험적 해석을 통해 두 접근방법의 타당성을 파악하였으며, 초고속카메라를 사용하여 액적의 다양한 변형 특성- 모드 형상, 분리, 미소 액적의 발생, 그리고 비틀림의 특성을 관찰하였다. 이론 해석 및 실험결과와의 비교에 있어 공진 주파수 값의 차이가 약 15% 이하라는 것이 도출되었으며 이러한 차이의 발생 원인으로 접촉선 마찰, 비선형벽 고착, 실험의 불확실성 등에 큰 영향을 받는 것으로 판단된다. 접촉선이 고정되어있을 경우와 작은 진폭 조건 하에서 액적의 모양은 대칭형상을 가졌으며, 공진 주파수에서의 로브의 크기는 주변부 주파수에서의 로브 크기보다 더 크게 된다는 점을 확인하였다. This study aims to understand the mode characteristics of a droplet under a periodic forced vibration. To predict the resonance frequency of a droplet, theoretical and experimental approaches were employed. A high-speed camera was used to capture the various deformation characteristics of a droplet- mode shape, detachment, separated secondary droplet, and skewed deformation. The comparison between the theoretical and the experimental approaches shows a ~10% discrepancy in the prediction of the resonance frequency, which appears to be caused by the effect of contact line friction, nonlinear wall adhesion, and experimental uncertainty. Owing to contact-line pinning and smaller amplitude, the droplet shape becomes symmetric and the size of each lobe at the resonance frequency exceeds that at the neighbor, which is out of resonance.
