Abstract As the main precursor of cardiovascular diseases, atherosclerosis is a complex inflammatory disorder that preferentially occurs in stenotic, curved, and branched arterial regions. Although various vitro models are established to understand its pathology, reconstructing native atherosclerotic environment involves both co‐cultured cells local turbulent flow singling remains challenging. This study develops an construct via in‐bath coaxial cell printing not only facilitates direct...
Owing to the prevalence of rotator cuff (RC) injuries and suboptimal healing outcome, rapid functional regeneration tendon-bone interface (TBI) after RC repair continues be a major clinical challenge. Given essential role in shoulder movement, engineering biomimetic multi-tissue constructs presents an opportunity for complex TBI reconstruction repair. Here, we propose gradient cell-laden construct combined with compositional TBI-specific bioinks via 3D cell-printing technology. In vitro...
Cerebral vessels are composed of highly complex structures that facilitate blood perfusion necessary for meeting the high energy demands brain. Their geometrical complexities alter biophysical behavior circulating tumor cells in brain, thereby influencing brain metastasis. However, recapitulation native cerebrovascular microenvironment shows continuities between vascular geometry and metastatic cancer development has not been accomplished. Here, we apply an in-bath 3D triaxial bioprinting...
Abstract To reconstruct an ideal full‐thickness skin model, basal keratinocytes must be distributed as a confluent monolayer on the dermis. However, currently available extrusion bioprinting method for is limited when producing air‐exposed cellular because cells are encapsulated within bioink. This first study to use sacrificial gelatin‐assisted reproduce uniform and stratified epidermal layer. Experimental analyses of rheological properties, printability, cell viability, initial...
Traumatic brain injury is one of the leading causes accidental death and disability. The loss parts in a severely injured induces edema, neuronal apoptosis, neuroinflammation. Recently, stem cell transplantation demonstrated regenerative efficacy an brain. However, current therapy needs improvement to resolve issues such as low survival implanted cells differentiation into respective cells. We developed brain-derived decellularized extracellular matrix (BdECM) bioink that printable has...
Abstract Non‐neural extracellular matrix (ECM) has limited application in humanized physiological neural modeling due to insufficient brain‐specificity and safety concerns. Although brain‐derived ECM contains enriched components, certain essential components are partially lost during the decellularization process, necessitating augmentation. Here, it is demonstrated that laminin‐augmented porcine brain‐decellularized (P‐BdECM) xenogeneic factor‐depleted as well favorable for regulation of...
Cancer microenvironment has a significant impact on the progression of disease. In particular, hypoxia is key driver cancer survival, invasion, and chemoresistance. Although several in vitro models have been developed to study hypoxia-related pathology, complex interplay observed vivo not reproduced yet owing lack precise spatial control. Instead, 3D biofabrication approaches proposed create microphysiological systems for better emulation ecology accurate anticancer treatment evaluation....
Given its ability to modulate neuronal excitability, low-intensity magnetic stimulation (LIMS) has therapeutic potential in the treatment of neurological disorders. However, underlying LIMS effects remain poorly understood because does not directly generate action potentials. We aimed elucidate these mechanisms by studying and systematically comparing neurochemical changes induced vitro LIMS. To this end, we developed a simple device that allowed delivery range parameters order sufficient...
Wi-Fi scanning that searches neighboring access points (APs) is an essential prerequisite for operations such as initial association and handover. As the traffic demand increases, APs are more densely deployed number of operating channels also which, however, results in additional delay makes a burdensome task. In this paper, we note co-location protocol with BLE common practice IoT networks, develop passive framework uses to assist scanning. Although has great potential improve performance...
Mobile gadgets including smartphones and laptops nowadays support both Wi-Fi Bluetooth together. The two protocols coexist in the 2.4GHz ISM band while sharing a single antenna order to meet constraints on form-factor. We call this kind of devices "Dual- stack devices" paper. Since dual-stack work TDM (Time Division Multiplexing) manner, performance Wi- Fi, specifically throughput, degrades inevitably. propose novel scheme, Opportunistic Antenna Utilization (OAU), which aims improve...

Korean Abstract: 본 연구는 우리나라와 인도 간의 교역의 발전과 다변화 및 긴밀화에 따라 국제공급망의 중추인 해운과 항만에서 협력방안을 제안하는 것을 목적으로 한다. 이에 구체적인 협력방안과 정책과제를 예시하여 향후 양국 정책입안자들이 용이하게 활용할 수 있도록 제안하고자 이러한 목적을 달성하기 위해 2장에서는 인도의 해운·항만 부문의 협력 환경을 경제 성장과 연계하여 파악하였다. 3장에서는 정책과 기업의 현황을 고찰하였으며, 4장에서는 거대 권역 중 항만산업이 긴밀한 뭄바이, 첸나이, 콜카타 권역을 중심으로 해운항만 물류 인프라를 분석하였다. 5장은 국제협력 수요를 정책 전문가 자문, AHP 기법을 통해 검토한 후 부분, 국제복합운송업에서 제안하였다. 6장은 인도간 시범사업을 제시하고 나아가 한국-인도간 항만 부분에서 정책적 협력과제와 관련 부처별·기관별 추진과제를 분석을 발견하게 된 점을 정리하면 다음과 같다(중략).English The purpose of...
Although the smart speaker market has experienced massive growth in recent years, there is a lack of research on what consumers really consider important for so called "smart" speakers, which are supposedly distinguished from traditional products. Therefore, this study aims at identifying key smartness dimensions that related to satisfaction users. First, total seven topics were extracted Amazon's review data through Latent Dirichlet Allocation, and mapped, group discussion, three elements...
본 연구는 인도 자동차 산업의 경쟁력을 파악하기 위해 47개 완성차 업체의 효율성과 결정요인을 분석하였다. 산업은 시장 규모 확대와 친환경 전환과 같은 경영환경 변화를 앞두고 있다. 이러한 가운데, 경쟁력 강화를 자료포락분석(DEA)을 통해 개별기업별 수익성을 검토하였다. 투입 변수로는 기업별 인건비, 고정자산, 총자본을 선택하였고, 산출변수는 매출액을 활용하였다. 산출지향 BCC 모형을 산출된 평균 효율성은 0.607이며, 효율성을 달성한 기업은 11개 업체로 나타났다. 5개 파악된다. 추가로, 기업 효율성의 토빗(Tobit) 분석도 진행하였다. 분석 결과, 그룹사 계열사에 소속된 기업의 유형이 효율성에 유의미한 영향을 미쳤다. 또, 자본 유동성, R&D 활동 등 요인이 긍정적인 미치는 것을 확인하였다.
