Professor Min-gu Lee's research lab specializes in sustainable environmental technologies and advanced biomedical applications. The lab focuses on carbon capture and utilization (CCU) technologies, particularly developing innovative processes for converting CO₂ into high-purity calcium carbonate using industrial wastewater and alkanolamine absorbents, with an emphasis on energy-efficient, continuous operation and absorbent recycling. In parallel, the lab explores bioactive phytochemicals, such as anthocyanin oligomers, for their anti-cancer properties in breast cancer cell lines. Additionally, the lab investigates secure communication systems using NFC and EAP/AAA protocols for next-generation smart authentication in healthcare and access control systems.

15Due to the special characteristics (limited battery power, limited computing capability, low bandwidth, need to collect sensor data from multiple fixed-location source nodes to a sink node that may be mobile, etc.) of wireless sensor networks, routing algorithms designed for general mobile ad hoc networks may not be directly applicable to wireless sensor networks. In one possible routing scheme for wireless sensor networks, each node maintains up-to-date hop-distances and next-hop nodes to the m
Abstract This study investigated the capture of carbon dioxide (CO 2 ) and its chemical conversion to high‐purity calcium carbonate salt, which has potential uses in a range of industrial sectors. Indirect inorganic aqueous carbonation methods were used, with seawater‐based industrial wastewater as the source of metal ions. The alkanolamine absorbent solutions of monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA) were used at typical industrial concentrations of 30 wt%
Carbon capture and utilization (CCU) technology is receiving notable attention because carbon capture and storage (CCS) technology has some limitations. Using solid waste or natural minerals, CO 2 capture can be achieved through the wet absorption-based CCU technology. This research proposes a novel process through which simultaneous and continuous carbon dioxide absorption, calcium component extraction, and production of calcium carbonate salt can be achieved. Also, recycling of the absorbent c
최근 NFC(Near Field Communcation) 기반 통신 기능을 채용한 스마트기기 및 OS 등이 확산됨에 따라 기존 RFID를 이용하던 다양한 응용 분야에 대하여 NFC로의 대체가 진행되고 있다. 대표적으로 출입 통제나, e-ticket, 전자 결제 등의 분야에서 NFC가 RFID를 대체하고 있다. 기존의 RFID는 수동적 통신 기능만 제공하여 충분히 안전한 인증 및 권한 검증 방법을 제시하지 못하였으나, 능동형 통신기능을 제공하는 NFC를 활용하면 보다 안전한 인증 방식을 제공하여 다양한 응용에서 요구하는 보안 요구사항을 만족시킬 수 있다. 그러므로 본 논문은 NFC의 능동형 통신 기능을 활용하여 신용카드 결제, 출입통제 시스템 등에 활용될 수 있는 능동형 인증 방식을 제공할 수 있는 방법으로 EAP(Extensible Authentication Protocol)과 AAA(Authentication. Authorization and Accounting) 규약을 활용하는
임상의학의 탄생에서 푸코는 질병의 공간화를 통해 다양한 층위에서 질병을 분석하였다. 의학 속의 질병, 몸에 자리 잡은 질병, 사회집단 속에 존재하는 질병이 각각 1, 2, 3차 공간에서의 질병이다. 2012년 중동에서 처음 보고된 중동 호흡기 증후군(메르스)이 2015년 한국에도 전파되어 의료사회 뿐만 아니라 사회 전반에 많은 후유증을 남겼다. 중동 호흡기 증후군은 푸코가 지적한 세 공간 모두에서 의미 있는 분석이 가능하다. 새로이 발견되어 질병의 본질에 대한 파악이 안 되어 있다는 점에서, 한국 의료 문화에서 개인의 의료 행동의 특징과 전염병의 관계에서, 인간의 이동능력이 크게 향상된 현대 사회에서 전염병 환자와 전염병 의심 집단의 관리 문제에서 각각 1, 2, 3차 공간 속 중동 호흡기 증후군에 대한 심도 있는 분석이 요구된다. 한국을 포함한 현대 사회에서 건강에 대한 관심과 욕구가 증대되고 개인의 이동성이 크게 향상되었기 때문에, 파급력이 큰 전염병과 같은 질병의 관리와 대처에
Anthocyanin oligomers (AOs) are phytochemicals synthesized by fermenting anthocyanins extracted from grape skins and are more biologically active than monomeric anthocyanins. In this study, we evaluate the effects of an AO on triple-negative MDA-MB-231 and HER2-overexpressing SK-BR-3 breast cancer cells. The cell viability of MDA-MB-231 and SK-BR-3 cells was significantly inhibited in a concentration-dependent manner by AO treatment for 24 h, while delphinidin (a monomeric anthocyanin) had no ef
Previous routing algorithms for mobile ad-hoc networks (MANETs) have focused on finding short-distance path(s) between communicating nodes. However, due to the dynamic and unreliable communication nature of MANETs, previously determined paths can easily become disconnected. Although dynamic routing can be used to circumvent this problem, determining a new route each time a packet needs to be sent involves a lot of overhead. An alternative form of dynamic routing involves maintaining valid routes
Based on recent advances in technology, many robots are developed and they are used in a hazardous environment such as military operation, fire, and building collapse and so on. Among them, reconnaissance robot should be able to perform various missions which people can not do. So it needs the capability of moving with hiding its position on rough terrain, overcoming obstacles, and guaranteeing its efficiency of reconnaissance. For this reason there are in progress of researching biomimetic robo
The purpose of this research is to develop a new 3D LIDAR sensor, named KIDAR-B25, for measuring 3D image information with high range accuracy, high speed and compact size. To measure a distance to the target object, we developed a range measurement unit, which is implemented by the direct Time-Of-Flight (TOF) method using TDC chip, a pulsed laser transmitter as an illumination source (pulse width: 10 ns, wavelength: 905 nm, repetition rate: 30kHz, peak power: 20W), and an Si APD receiver, which
