Carbon abatement costs and the potential of South Korea's power sector

South Korea has set a 2030 target to reduce greenhouse gas emissions by 37 percent from the business-as-usual (BAU) level. Its power sector is expected to play a significant role in achieving this target as it accounts for more than 35% of total national emissions. This thesis examines the emissions reduction potential and costs of South Korea’s power sector by constructing a marginal abatement cost curve. Two scenarios were developed for analysis. One is a reference case, in which the current fossil fuel-based generation mix is maintained until 2029. And alternative scenario allows low-carbon measures, such as new and renewable energy, nuclear, and carbon capture and storage (CCS) built out to their maximum potential. The carbon abatement cost curve was created by comparing the two scenarios so as to indicate which abatement measures are cost-effective in terms of reducing South Korea’s power sector emissions.Energy and Earth Resource

RPC Gap Production and Performance for CMS RE4 Upgrade

CMS experiment constructed the fourth Resistive Plate Chamber (RPC) trigger station composed of 144 RPCs to enhance the high momentum muon trigger efficiency at both endcap regions. All new CMS endcap RPC gaps are produced in accordance with QA and QC at the Korea Detector Laboratory (KODEL) in Korea. All qualified gaps have been delivered to three assembly sites: CERN in Switzerland, BARC in India, and Ghent University in Belgium for the RPC detector assembly. In this paper, we present the detailed procedures used in the production of RPC gaps adopted for the CMS upgrade.Comment: RPC2014 conference contribution, 7 pages, 8 figure

Mid-Holocene Northern Hemisphere warming driven by Arctic amplification.

The Holocene thermal maximum was characterized by strong summer solar heating that substantially increased the summertime temperature relative to preindustrial climate. However, the summer warming was compensated by weaker winter insolation, and the annual mean temperature of the Holocene thermal maximum remains ambiguous. Using multimodel mid-Holocene simulations, we show that the annual mean Northern Hemisphere temperature is strongly correlated with the degree of Arctic amplification and sea ice loss. Additional model experiments show that the summer Arctic sea ice loss persists into winter and increases the mid- and high-latitude temperatures. These results are evaluated against four proxy datasets to verify that the annual mean northern high-latitude temperature during the mid-Holocene was warmer than the preindustrial climate, because of the seasonally rectified temperature increase driven by the Arctic amplification. This study offers a resolution to the "Holocene temperature conundrum", a well-known discrepancy between paleo-proxies and climate model simulations of Holocene thermal maximum

An Examination On Factors That Influence The Creation Of Economic Value Added To The Professional Teams: Focusing On Korea Baseball Organization (KBO)

The research seeks to derive the economic value added (EVA) of 6 franchises from the Korea Baseball Organization (KBO) and concurrently investigate the revenue components contributing to EVA. EVA is regarded as one of the efficient methods on estimating or assessing corporations’ actual economic benefits. For the procedure, financial statements of domestic professional baseball teams for 3 consecutive years (2016-2018), which were released to the Data Analysis Retrieval and Transfer System (DART) of the Financial Supervisory Service (FSS), were utilized. First, NOPLAT, IC, ROIC, and WACC, which refer to essential elements of estimating the EVA, were calculated respectively. Second, Pearson's correlation analysis was conducted between the EVA and the profit indicated in the income statement of the 6 teams. The results of the study are as follows: In case of Doosan, LG and SK, main business revenues showed the highest correlation with EVA, and Kiwoom and Samsung showed the highest correlation with EVA through the contributing factor of ticket sales revenue. Finally, for Lotte, advertising revenue was highly correlated with bringing EVA to the tea

Rim 2/Hipa CACTA transposon display ; A new genetic marker technique in Oryza species

BACKGROUND: Transposons constitute the major fractions of repetitive sequences in eukaryotes, and have been crucial in the shaping of current genomes. Transposons are generally divided into two classes according to the mechanism underlying their transposition: RNA intermediate class 1 and DNA intermediate class 2. CACTA is a class 2 transposon superfamily, which is found exclusively in plants. As some transposons, including the CACTA superfamily, are highly abundant in plant species, and their nucleotide sequences are highly conserved within a family, they can be utilized as genetic markers, using a slightly modified version of the conventional AFLP protocol. Rim2 /Hipa is a CACTA transposon family having 16 bp consensus TIR sequences to be present in high copy numbers in rice genome. This research was carried out in order to develop a Rim2/Hipa CACTA-AFLP or Rim2/Hipa CACTA-TD (transposon display, hereafter Rim2/Hipa-TD) protocol for the study of genetic markers in map construction and the study of genetic diversity in rice. RESULTS: Rim2/Hipa-TD generated ample polymorphic profiles among the different rice accessions, and the amplification profiles were highly reproducible between different thermocyclers and Taq polymerases. These amplification profiles allowed for clear distinction between two different ecotypes, Japonica and Indica, of Oryza sativa. In the analysis of RIL populations, the Rim2/Hipa-TD markers were found to be segregated largely in a dominant manner, although in a few cases, non-parental bands were observed in the segregating populations. Upon linkage analysis, the Rim2/Hipa-TD markers were found to be distributed in the regions proximal to the centromeres of the chromosomes. The distribution of the Rim2/Hipa CACTA elements was surveyed in 15 different Oryza species via Rim2/Hipa-TD. While Rim2/Hipa-TD yielded ample amplification profiles between 100 to 700 bp in the AA diploid Oryza species, other species having BB, CC, EE, BBCC and CCDD, profiles demonstrated that most of the amplified fragments were larger than 400 bp, and that our methods were insufficient to clearly distinguish between these fragments. However, the overall amplification profiles between species in the Oryza genus were fully distinct. Phenetic relationships among the AA diploid Oryza species, as evidenced by the Rim2/Hipa-TD markers, were matched with their geographical distributions. CONCLUSION: The abundance of the Rim2/Hipa TIR sequences is very informative since the Rim2/Hipa-TD produced high polymorphic profiles with ample reproducibility within a species as well as between species in the Oryza genus. Therefore, Rim2/Hipa-TD markers can be useful in the development of high-density of genetic map around the centromeric regions. Rim2/Hipa-TD may also prove useful in evaluations of genetic variation and species relationships in the Oryza species
