김다현,박만복,안준호,Kim, Da-hyeon,Park, Man-bok,Ahn, Jun-ho 한국인터넷정보학회 2022 인터넷정보학회논문지 Vol.23 No.4

화재, 붕괴, 자연재해 등의 재난 발생으로 건물 내부가 붕괴하는 경우, 기존의 건물 내부의 물리적 보안이 무력해질 확률이 높다. 이때, 붕괴 건물 내의 인명피해와 물적 피해를 최소화하기 위한 물리적 보안이 필요하다. 따라서 본 논문은 기존 연구되었던 장애물을 탐지하고 건물 내 붕괴된 지역을 탐지하는 연구와 인명피해를 최소화하기 위한 딥러닝 기반 객체 탐지 알고리즘을 융합하여 재난 상황의 피해를 최소화하기 위한 알고리즘을 제안한다. 기존 연구에서 단일 카메라만을 활용하여 현재 로봇이 있는 복도 환경의 붕괴 여부를 판단하고 구조 및 수색 작업에 방해가 되는 장애물을 탐지했다. 이때, 붕괴 건물 내 물체는 건물의 잔해나 붕괴로 인해 비정형의 형태를 가지며 이를 장애물로 분류하여 탐지하였다. 또한, 재난 상황에서 자원 중 가장 중요한 요구조자를 탐지하고 인적 피해를 최소화하기 위한 방법을 제안하고 있다. 이를 위해, 본 연구는 공개된 재난 영상과 재난 상황의 이미지 데이터를 수집하여 다양한 딥러닝 기반 객체 탐지 알고리즘을 통해 재난 상황에서 요구조자를 탐지하는 정확도를 구했다. 본 연구에서 재난 상황에 요구조자를 탐지하는 알고리즘을 분석한 결과 YOLOv4 알고리즘의 정확도가 0.94로 실제 재난 상황에서 활용하기 가장 적합하다는 것을 증명하였다. 본 논문을 통해 재난 상황의 효율적인 수색과 구조에 도움을 주며 붕괴된 건물 내에서도 높은 수준의 물리적 보안을 이룰 수 있을 것이다. If the inside of a building collapses due to a disaster such as fire, collapse, or natural disaster, the physical security inside the building is likely to become ineffective. Here, physical security is needed to minimize the human casualties and physical damages in the collapsed building. Therefore, this paper proposes an algorithm to minimize the damage in a disaster situation by fusing existing research that detects obstacles and collapsed areas in the building and a deep learning-based object detection algorithm that minimizes human casualties. The existing research uses a single camera to determine whether the corridor environment in which the robot is currently located has collapsed and detects obstacles that interfere with the search and rescue operation. Here, objects inside the collapsed building have irregular shapes due to the debris or collapse of the building, and they are classified and detected as obstacles. We also propose a method to detect rescue requesters-the most important resource in the disaster situation-and minimize human casualties. To this end, we collected open-source disaster images and image data of disaster situations and calculated the accuracy of detecting rescue requesters in disaster situations through various deep learning-based object detection algorithms. In this study, as a result of analyzing the algorithms that detect rescue requesters in disaster situations, we have found that the YOLOv4 algorithm has an accuracy of 0.94, proving that it is most suitable for use in actual disaster situations. This paper will be helpful for performing efficient search and rescue in disaster situations and achieving a high level of physical security, even in collapsed buildings.

반도체 산업의 실리콘(Si) 제조과정에서 실리콘과 실리콘 카바이드(SiC)를 포함하는 폐 슬러리가 발생하게 된다. 폐 슬러리는 단순히 시멘트로 고형화하여 보관하거나 매립하는 방법이 있지만, 본 연구에서는 제강공정의 부원료인 승온제로 사용하는 방안이 제시되었다. 폐 슬러리를 정제하여 분말을 만들어 SiC계 슬러지 브리켓으로 재활용하였다. SiC계 슬러지 브리켓은 화학적 성분을 분석하고 투입시기와 투입량에 따른 승온제 특성을 관찰하였다. 이 결과 SiC계 슬러지 브리켓은 제강공장에서 저비용과 고효율로 용강온도를 높이는 효과가 있었다. Most Waste slurry is produced in the process of silicon manufacturing for semiconductor industry, containing silicon (Si) and silicon carbide (SiC). Waste slurry is simply stored with solidifying by cement or buried. On the other hand, it was suggested in this study that the waste slurry should be used for heating source as supplementary material in steel making process. The waste slurry was refined and pulverized, which was recycled into SiC-based sludge briquette. Chemical composition for SiC-based sludge briquette was analyzed and the feature of heating source was observed in accordance with the injection time and input amount. As a result, SiC-based sludge briquette in terms of low cost and high efficiency had an effect on increasing liquid steel temperature in steel making plants.

백민숙,조사현,박만복,윤동주,허기복,Baek, Min-Sook,Cho, Sa-Hyeon,Park, Man-Bok,Yoon, Dong-Joo,Heo, Ki-Bok 한국재료학회 2016 한국재료학회지 Vol.26 No.8

In this study, the recently developed Al 2013 alloy was T8-tempered and, to improve the strength and corrosion-resistance, slight amounts of Zr of 0.2 wt% and 0.5 wt%, respectively, were added and the mechanical properties were analyzed. For microstructure and precipitate analysis, OM observation, XRD analysis, and TEM analysis were performed, and for the mechanical property analysis, hardness and tensile strength tests were done. Also, in order to determine the corrosion rate according to the Zr content, a potentiodynamic polarization test was performed and the properties were compared and analyzed. The size of the precipitate varied with the content of Zr and was finest at Zr content of 0.2 wt%; it grew larger at 0.5 wt%, at which point the hardness value accordingly showed the same trend. On the other hand, as calculated from the aspect of chemical bonding among atoms, it was confirmed that the tensile strength and the corrosion-resistance increased with the same trend.

이상로,김상열,이만승,박만복,Lee, Sang-Ro,Kim, Sang-Yeol,Lee, Man-Seung,Park, Man-Bok 한국자원리싸이클링학회 2015 資源 리싸이클링 Vol.24 No.2

현재 국내에서 소비되는 주석의 대부분은 수입에 의존하고 있다. 본 연구에서는 평판 유리, LCD 패널 유리 기판 생산시 발생하는 주석 용탕에 함유된 주석산화물을 건식법으로 회수하는 공정을 조사하였다. 환원반응온도를 변화시키며 주석의 회수율을 조사한 결과 $1350^{\circ}C$에서 최대 회수율을 얻을 수 있었다. 또한 주석 산화물의 1차 제련과 슬래그의 2차 제련을 통해 88%의 회수율을 얻었다. 건식공정으로 회수된 조주석을 전해정련처리하여 99.9%의 순도를 지닌 주석 금속을 제조하였다. Most of the domestic need for tin rely on imports. In this work, a pyrometallurgical process was investigated to recover pure tin from the tin oxides in tin bath which results from the production of flat glass and LCD panel. From the results on the effect of reaction temperature, the highest recovery percentage of tin was obtained at $1350^{\circ}C$. The recovery percentage of tin was improved to 88% by employing the first and second smelting step. Electrorefining of the crude tin thus obtained led to pure tin with purity higher than 99.9%.
