  • Korean Emission Trading Scheme entered into force on 1 January 2015. As other Emission Trading Systems, Korean Emission Trading System also have some deficiencies to be complemented and improved. Thus, the issues that are related to legal characteristics of emission allowance and its status as a financial instrument, terminology, requisites for the designation of the business entities eligible for allocation, banking and borrowing, and the non-permanence problems in the forestry offset mechanism are reviewed and the directions of the improvement are presented. The review of the Korean Emission Trading Scheme and its relevant act and the presidential decree at its early stage may be helpful for the Korean ETS to be firmly settled and to operate properly.

  • This study was conducted to investigate the effects of in vitro human digestion on the antioxidant activity of blueberry leaf extracts (BLE) in emulsion-type sausages (ETS). Leaves from four cultivars of blueberries (Bluecrop, Bluegold, Duke, and Northland) collected from a wild blueberry farm were extracted with 80% ethanol. ETS were prepared with 0.2% BLE. The samples were then passed through an in vitro human digestion system which simulates the composition of the mouth, stomach, and small intestine juice. Only one phenolic compound (chlorogenic acid) was detected in the BLE. Northland BLE had appreciably higher amounts of chlorogenic acid than that of other BLE, both before and after in vitro human digestion. Antioxidant activity of any BLE was not influenced by in vitro human digestion, whereas the antioxidant activity of chlorogenic acid standard increased in response to in vitro human digestion in both 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and ferric-reducing ability of plasma (FRAP). In the present study, the antioxidant activities of the BLE were not strongly influenced by in vitro human digestion, and the antioxidant activity depended on the chlorogenic acid content of ETS. Thus, compounds from blueberry leaves may have important applications in the future as natural antioxidants for meat products.

  • The introduction of aviation into the EU-ETS has faced significant opposition from many ICAO member States. Accordingly a global solution through ICAO is in progress. This paper traces the progress of works done by the HGCC in the area of global aviation aspiration goals aiming for the submission to the 38th Session of the ICAO Assembly. Furthermore, devices for calculating the carbon dioxide emissions from flights have been developed by several agencies including international organizations, governments, airlines and nongovernmental organizations. These carbon calculators, however, introduce too many assumptions to simplify the calculation process. This study assesses carbon calculators for aviation emissions and suggests a modified calculation methodology using the pre-existing computer reservation system for better accuracy.

  • Although awareness of the need to respond to climate change is expanding, various controversies are being raised about the EU's Carbon Border Adjustment Mechanism (CBAM). The EU has announced that they will implement CBAM as responding to climate change and preventing carbon leakage. However, the questions are raised as to whether it is actually effective in preventing carbon leakage. Above all, CBAM has its own contradictions, thus it could not be easy to implement. This is because the possibility of violation of the WTO principles is high and there are many issues in implementation. Emission Trading System (ETS) based on CBAM differs by country, and international linkage is not easy in that ETS is not a widely used system worldwide. The EU's CBAM is highly likely to be used as a trade restrictive tool, and is inevitably subject to trade disputes in that it imposes additional tariffs. The unilateral implementation of CBAM should be restrained unless support from the international community and consideration for developing countries are not taken into account.

  • The Kyoto Protocol has extended its life until 2020 by the decision at COP18 in Doha, Qatar in 2012. So has the Kyoto Mechanism of CDM, JI, and ETS. Nonetheless, the sustainability of CDM projects is jeopardized by the recent rule changes in the international emissions trade market such as EU ETS and the price decrease in emission credits. In particular, the domestic CDM projects reducing non-$CO_2$ GHG emissions are being directly affected. This study examines the trend of carbon credit price change in the international market. It also examines how the rule changes in the international emissions trade market have affected domestic non-$CO_2$ CDM projects through which mechanisms. The policy implications drawn from this study is two-fold: it suggests how the government can assist the project developers in utilizing GHG emission reduction technologies and the market in promoting investment environment before the domestic ETS enters into effect in 2015; apart from possible measures within ETS, an additional measures such as bilateral carbon offset system is suggested to help the private sector reduce uncertainty in investment and increase options to choose.

  • This study examines the determinants of net export of electricity among 30 European countries sharing electricity grid during the period of 1990~2014 by separating the sample period before and after 2005 in which ETS was introduced in Europe. The empirical method used in this study is generalize least squared one considering both heterogeneous and serial correlation in the balanced panel data. According to the empirical results, after 2005 introducing the ETS, holing energy resources, concentrating only on few electricity generation resources, and nuclear electricity generation had played more important role in net export of electricity, while renewable energy had negative effect on net export of electricity and coal and gas generation have no effect on net export after introduction of ETS in Europe probably because of high environmental cost. The policy implication of the results would be that reconsidering each country's optimal generation mix strategy and its role in case freely trading electricity.

  • This paper is an overview of the experimental work using a Planar Magnetic Levitation Stage System structure proposed by Dr. Won-Jong Kim in his PhD thesis. Based on his results, we built an Experimental Test Stand (ETS), which enabled us to get accustomed with the new technology and to create new control structures and algorithms. The ETS is controlled by a powerful controller made of 4 DSPs mastered by a PC. This controller structure increases the controller bandwidth up to 10 kHz leading to a better emulation of an analog controller and leaving enough room for further development. Based on analyzing all the factors that can affect the performances of the system, we achieved a great accurate positioning performance of sub-nanometer RMS value.

  • The ROK Navy is seeking to secure an aircraft carrier(CVX) to take responsibility for the maritime security of the Republic of Korea. In order for the CVX to complete the mission given to it, the crew must be able to operate the CVX perfectly, and for this purpose, the operating skills of the CVX crew result from constant training. Therefore, this paper proposes an On-board Training System(OBTS) so that the best training can always be performed even on ship. CVX OBTS should be built in the form of a thorough simulator based on a Synthetic Training Environment(STE) so that it can be optimally applied to ship and provide the best training environment to the crew. In order to satisfy the various training requirements and implementation conditions of the CVX, this paper proposes a plan to consist of Embedded Training System(ETS), VR training system, AR maintenance system, MR training system, MR metaverse training system, and realistic simulator training system.

  • Global aviation is projected to grow in demand by an annual average of 4.1% between 2014 and 2034. It can be said that environmental impact from aviation will therefore be expected to increase on a similar scale. As regards civil aviation emissions, the sector contributes between 2~3% to International aviation GHG emissions. In the European Union(EU), aviation emissions account for about 3% of the EU's total green house gas emissions, of which a majority are said to come from international flights. In terms of traffic volume in 2013, Korea's international aviation industry 11th with regard to passengers and 3rd with regard to cargo, attaining the overall rank of 5th in the world. GHG emissions has been increasing steadily over the last 4 years, averaging 3.9 percent a year, due to the growth of low cost carriers and the increased demand for air transportations. As for aviation in Korea, there are a number of means intended to attain the Government's emission control objective in an efficient manner, such as AVA (Agreement of Voluntary Activity), TMS (Target Management System) and ETS (Emission Trading Scheme). In addition, the Government intends to better adapt to ICAO's Global MBM(Market-based Measures) that will come into performance on Year 2020. In the study, we focused on GHG mitigation measures that is fulfilling the AVA, TMS, ETS in the Government and suggest the effective measures to reduction the aviation GHG emissions.

  • The aim of this study was to investigate the alterations in meningeal blood flow by stimulation of trigeminovascular system. An open cranial window was prepared on the right parietal bone of male Sprague-Dawley rats. Trigeminovascular system was stimulated by electrical stimulation of trigeminal ganglion (ETS), somatosensory (whisker) stimulation, or topical applications of capsaicin and neuropeptides including substance P and calcitonin gene-related peptide (CGRP). Neonatal capsaicin pretreatment was performed with subcutaneous administration of capsaicin (50 mg/kg) within the first 24 hours after birth. Changes in regional blood flow of dural artery (rDBF) and pial artery (rPBF) were continuously measured through the cranial window by laser-Doppler flowmetry. Both ETS and capsaicin caused a chain of alterations in rPBF and rDBF responses, i.e., an immediate transient decrease followed by rapid and marked increase in rPBF, which were significantly attenuated not only by pretreatments with L-733,060, a $NK_1$ receptor blocker, $CGRP_{8-37}$, a $CGRP_1$ receptor blocker, and 7-nitroindazole monosodium salt (7-NINA), a neuronal nitric oxide synthase inhibitor but also by neonatal capsaicin treatment. Exogenous neuropeptides including substance P and CGRP increased the meningeal blood flow, which was significantly attenuated not only by pretreatment with L-733,060 and $CGRP_{8-37}$, respectively, but also by pretreatment with 7-NINA. The rPBF response to whisker stimulation was significantly attenuated not only by trigeminovascular system injuries including nasociliary nerve denervation and neonatal capsaicin treatment but also by pretreatments with L-733,060, $CGRP_{8-37}$ and 7-NINA. These results suggest that the stimulation of trigeminovascular system causes prominent alterations in meningeal blood flow, and that neuropeptides as well as nitric oxide in the trigeminovascular system are importantly implicated in the regulation of meningeal blood flow.
