Abstract The epidermal growth factor (EGF) and insulin-like (IGF) signaling pathways are critically involved in cancer development progression. However, how these two signals cross-talk with each other to regulate cell is not clearly understood. In this study, we found that EGF remarkably induced expression of major IGF components, insulin receptor substrate (IRS)-1 IRS-2, an effect could be blocked by (EGFR) tyrosine kinase inhibitors. Although both extracellular signal-regulated c-Jun...

South Korea, which has led in “green growth” since 2012, is now focusing on investigating new-growth engine industries such as the gaming industry and mega-resort development. Yeongjong Island most representative promising location for nurturing industry, already generated more than 20 billion USD. However, construction of mega resort clusters generates critical energy issues. Despite this potential problem, local governments Korea’s central government have not yet established a sustainable...

South Korea’s main industry is the manufacturing industry, and it requires stable energy. Korea heavily relies on importing oils to produce energy, thus efficient energy management critical. This why many renewable smart policies infrastructure planning are being set up currently. Supplying reliable sustainable remote areas has especially been questioned; therefore, adopting clean based resources cannot be delayed any more. research examines most economically, technologically environmentally...

In response to global energy problems (e.g., the oil crisis, Fukushima accident, Paris Agreement), South Korean government has executed a strict renewable plan decrease country’s dependence on fossil fuel. Public facilities, such as international airports, which use substantial amounts of electricity, are most in need regulation. this study, we attempt determine optimal hybrid electricity generation system for Korea’s largest airport: Incheon International Airport. analysis, three scenarios:...

We report the feasibility of ultralow- <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${k}$ </tex-math></inline-formula> amorphous boron nitride ( notation="LaTeX">$\alpha $ -BN) film as a new capping layer for copper (Cu) interconnects. -BN thin films were successfully deposited using plasma-enhanced chemical vapor deposition (PECVD) process. The CVD-grown showed -value low 2.0 at 3 nm thickness, leakage...

Greenhouse gas (GHG) emissions, which are produced through the combustion of fossil fuels, cause climate change. Unfortunately, South Korea is highly dependent on fuels because its industrial nature. However, many islands in have potential to generate a considerable amount renewable energy, should be studied. KEPCO (Korea Electricity Power Corporation), runs micro-grid facilities Gasado Island Jindo, Korea, built Mozambique 2015. The construction considered one most successful projects...

For realizing sustainable development, EV (Electric Vehicle) is currently considered as one of the most promising alternative due to its cleanness and inexhaustibility. However, development dissemination has stagnated because it faces major constraints such battery performance an excessively long charging time. Thus, this study examined feasibility using EVs taxis by analyzing real data from a pilot project in Daejeon, metropolitan city South Korea for proposing effective way adopt EV. To...

With rapidly increasing interest in several significant environmental and transportation issues, namely, greenhouse gas emissions, there have been attempts to transition the current systems vehicles more environment-friendly vehicles. Following this trend, study aimed investigate drivers' motivations for adopting electric-powered taxis two representative nations, South Korea U.S. This conducted a main survey collected data from professional taxi-drivers explore differences between nations....

Due to heavy fuel dependence, the “renewable energy system” idea is an important issue in South Korea. The government of Korea endeavoring convert its infrastructure into renewable generation. As such, numerous studies have evaluated economic feasibility various sources This study differs from those as it focused on a smaller scale terms self-supporting nanogrid and microgrid energy. purpose this determine which type grid more economical. To conduct comparative nanogrids microgrids, three...

Monolithic 3-D (M3D) integration has been spotlighted as an approach to overcome the limitation of classical scaling in integrated circuits (IC). However, fabrication top-tier devices M3D is challenging because limited maximum thermal budget during process. In this work, a nanosecond annealing process using pulsed green laser introduced fabricate and minimize influence on bottom-tier devices. With laser, average temperature gradient along vertical direction within was reduced much 26%,...
