Vibration signs suggest system’s wellbeing. It frees that the requirement of bringing vibration intensity to limitation. Researchers have been focusing on several different varieties of vibration isolators as well as also their calculating regarding space involvement, dependability, price and fat. Inside this newspaper, an endeavor was designed to present the most basic theories of Magnetorheological Fluids (MRF) that may function as a more semi-active vibration isolator, for its rookies and investigators

“…The approach we take to compile the GHG satellite table of KREEIO generally follows that used in previous studies. ,,− We first estimate CO 2 emissions for different energy sources consumed by the aggregated sectors in the energy balance table using corresponding emission factors (Table S2 in the SI). For some energy sources like naphtha, a carbon storage fraction is applied . Specifically, fuel CO 2 emissions (in kiloton (kt)) by sector are calculated by where NA ij is the fuel use (in 1000 toe), FCS ij is the carbon storage fraction (%), 41.868 is the joule-toe conversion coefficient (TJ/1000 toe), CF i is the conversion coefficient (net calorific value/total calorific value), EF i is the emission coefficient (tC/TJ), OF i is the oxidation ratio, 44/12 is the conversion rate from carbon to carbon dioxide (kg CO 2 / kg C), i is the fuel type, and j is the sector.…”

“…For some energy sources like naphtha, a carbon storage fraction is applied. 33 After each sector's direct emissions are estimated, their values are divided by sectoral outputs to derive direct emissions intensities (i.e., GHG emissions per dollar worth of output) for footprint analyses. All results calculated by our model reflect the situations of 2017.…”

South Korea is a global leader in electronics, but little is known about their climate change impact. Here, we estimate the direct and indirect greenhouse gas (GHG) emissions of Korean electronics by developing a new and high-resolution (∼380 sectors) environmentally extended input−output model, named KREEIO. We find that final demand for Korean electronics led to nearly 8% of national GHG emissions in 2017, mostly because of indirect emissions embodied in the electronics supply chain. Notably, the semiconductor and display sectors contributed 3.2% and 2.4% to national emissions, with capital investment accounting for 17% of the two sectors' total emissions or nearly 1% of national emissions. For other electronic products, scope 1, scope 2, and upstream scope 3 emissions on average accounted for 3%, 10%, and 87% of a sector's GHG intensity, respectively. Detailed contribution analysis suggests that reducing Korean electronics GHG emissions would benefit most from the transition to a low-carbon electricity grid, but mitigation efforts in many other sectors such as metals and chemicals are also important. Overall, our study underscores the significance of electronics GHG emissions in South Korea, especially those from semiconductors and displays, and the mitigation challenges these sectors face as demand continues to grow globally.

Objectives : As climate change deepened, the concept of 2050 carbon neutrality was introduced. The COP 26 Glasgow Agreement strengthened the national greenhouse gases (GHGs) target of 2030. However, there are controversies over the feasibility of these GHGs reduction goals, considering the economic sectors energy policy and the attributes of GHGs emissions. Taking this into consideration, this study aimed to formulate the 2017 Environmentally Expanded Input-output Table to analyze the characteristics of GHGs emissions in Korea's economic sectors.Methods : The carbon dioxide emission was calculated by multiplying carbon dioxide emission factors to fuel consumption in the 2017 energy balance table, while other GHGs emissions are taken from the national GHGs inventory. All the GHGs emissions calculated and taken were allocated to 381 basic sectors of the Input-Output Table to represent each sector's characteristics of GHGs emissions. Then 381 sectors are combined into a large category of 35 sectors to formulate the 2017 Republic of Korea Environmentally Extended Input-Output Table (ROKEEIOT). Using this ROKEEIOT, the emission of Scope 1. 2, and 3 by economic sectors were estimated, and the GHGs emissions and GHGs intensity by economic sectors.Results and Discussion : The carbon dioxide emissions calculated by the 2017 ROKEEIOT prepared in this study showed a difference of 2% from the 2017 national GHGs emission statistics, confirming that the 2017 ROKEEIOT is very effective. The three economic sectors with the highest direct GHGs emissions were electricity, steam, chilled or hot water, air conditioning supply (262,280 kt CO2eq.), primary metal products (117.098 kt CO2eq.), and transportation equipment (58,332 kt CO2eq.). However, the total GHGs emissions were different in the order of construction (151,476 kt CO2eq.), transportation equipment (112,168 kt CO2eq.), computer, and electronic and optical instruments (107,868 kt CO2eq.). As a result of classifying the scope of GHGs emissions, 6 industries exceeded 50% in Scope 1, and 29 sectors exceeded 50% in Scope 3, indicating that GHGs reduction measures were necessary for the supply chain in consideration of the GHGs emissions characteristics by economic sectors. In particular, 41.68% of GHGs emissions induced by final demand were generated by exports confirming, confirming the urgent need to strengthen the carbon competitiveness of export industry in preparation for the introduction of the carbon border adjustment mechanism.Conclusion : The economic contribution, direct GHGs emissions of industries, and the amount of GHGs emissions induced by supply chains and value chains show very different patterns by economic sectors. Therefore, it was confirmed that scientific policies to reduce GHGs emissions, such as net-zero and climate change measures, should reflect the characteristics of Scope 1, which is direct emission by industry, Scope 2 emissions caused by electricity and steam consumption and scope 3 emissions generated along the supply chain or value chain.
