  • The Paris Agreement, adopted in 2015, requires global mitigation actions by all countries, whether they are developed or developing countries. All member countries prepared and communicated a greenhouse gas reduction target, formally called the Intended Nationally Determined Contribution (INDC). There has been some concern regarding whether the INDCs communicated are sufficient to achieve the emissions reduction needed to hold the increase in global temperature to $2^{\circ}C$ above pre-industrial levels. How to address this emissions gap in an equitable and fair manner remains controversial. Beginning in the year 2023, global stocktaking under the Paris Agreement will be performed by the Conference of the Parties to assess progress towards temperature goals. The present study, based on various composite indicators reflecting equity, fairness, ability and efficiency, analyzed the GHG reduction targets of eleven major countries and the ambitiousness of these targets. Employing share indicators and comparative ratio indicators (resulting in eight composite indicators), this study showed that when share indicators are applied, Korea's appropriate reduction requirement rate is relatively low at 1~2%. However, when comparative ratio indicators are applied, Korea's appropriate reduction requirement rate increases dramatically to 6~11%. In a similar vein, when share indicators are applied, Korea's 2030 target is very ambitious compared to other countries, while the opposite is seen with comparative ratio indicators. This strongly suggests that Korea needs to apply more share indicators than comparative ratio indicators when discussing the equitable and ambitious role of Korea in the climate debate.

  • A Gram-positive bacterium was isolated from the saline soils of Jangpura (U.P.), India, and showed high-level of radiation-resistant property and survived upto 12.5 kGy dose of gamma radiation. The 16S rDNA sequence of this strain was examined, identified as Bacillus sp. strain HKG 112, and was submitted to the NCBI GenBank (Accession No. GQ925432). The mechanism of radiation resistance and gene level expression were examined by proteomic analysis of whole-cell extract. Two proteins, 38 kDa and 86.5 kDa excised from SDS-PAGE, which showed more significant changes after radiation exposure, were identified by MALDI-TOF as being flagellin and S-layer protein, respectively. Twenty selected 2-DE protein spots from the crude extracts of Bacillus sp. HKG 112, excised from 2- DE, were identified by liquid chromatography mass spectrometry (LC-MS) out of which 16 spots showed significant changes after radiation exposure and might be responsible for the radiation resistance property. Our results suggest that the different responses of some genes under radiation for the expression of radiation-dependent proteins could contribute to a physiological advantage and would be a significant initial step towards a fullsystem understanding of the radiation stress protection mechanisms of bacteria in different environments.

  • This study is concerned with the comparative linguistic analysis of the Korean and Mongolic costume terminologies. The results of this research revealed that there were relationships between some of the Korean and Mongolic costume terminologies. It was also found that some of the Korean costume terminologies were originated from the Mongolic costume terminologies t the same time some of the Korean costume terminologies were influenced by the Mongolic costume terminologies. It also appeared that some of the Koran and Mongolic costume terminologies were greatly influenced by the Chinese costume terminologies.

  • A comparative molecular field analysis (CoMFA) on the substituent effect of the palladium(Ⅱ) catalyzed [3,3]-sigmatropic rearrangement of allylic esters was studied to show a good correlation between the electrostatic property of substituents and the reaction rate. The CoMFA result suggests that the reaction rate will increase as the electron-donating ability of substituents increases.

  • Since the crisis at the Fukushima plants, severe accident progression during a station blackout accident in nuclear power plants is recognized as a very important area for accident management and emergency planning. The purpose of this study is to investigate the comparative characteristics of anticipated severe accident progression among the three typical types of nuclear reactors. A station blackout scenario, where all off-site power is lost and the diesel generators fail, is simulated as an initiating event of a severe accident sequence. In this study a comparative analysis was performed for typical pressurized water reactor (PWR), boiling water reactor (BWR), and pressurized heavy water reactor (PHWR). The study includes the summarization of design differences that would impact severe accident progressions, thermal hydraulic/severe accident phenomenological analysis during a station blackout initiated-severe accident; and an investigation of the core damage process, both within the reactor vessel before it fails and in the containment afterwards, and the resultant impact on the containment.

  • This is a comparative cultural study on the cultural dimensions of the Korean original film and its Chinese remake film. This research is based on the cultural dimension study by Dutch organizing psychologist Geert Hofstede (1991). In this research I have tried to compare cultural dimensions that are shown implicitly in the original Korean film of "Blind" and its Chinese remake, entitled "The Witness", in terms of the narrative structures.

  • The purpose of this study was to conduct a comparative study between Korea and the United States to examine anglers' motivations, consumptive orientation, and the relationship between these two concepts. The following two research questions were explored: (1) whether there are significant differences in anglers' motivations and consumptive orientation between Korea and the United States; and (2) what differences exist in the effects of anglers' motivations on consumptive orientation between these two countries. The main research results are as follows. First, Korean anglers showed a higher level of consumptive orientation than American anglers. Second, a positive relationship between activity-general motivation and consumptive orientation was reported for Korean anglers while the relationship was opposite for American anglers. Study results imply that national angler surveys as well as public education and outreach programs are necessary to help anglers engage in sustainable fishing behaviors for effective fishery resources management.

  • This is a comparative study on the policy of Korea and Japan for improving upland farming mechanization. Purpose of the study is to set a policy direction of improving efficiency of farm management by using agricultural machinery. Research topic is the agricultural mechanization policy at the national level. The research attempts to classify mechanization policies into framework plan, R&D, rent and lease program, upland farm promotion policies. Major features of the comparative analysis are followed. First, there is a similarity between policies of Korea and Japan in terms of the aim of framework plan and other policies settings. However, Japanese policies focus more on the joint management of farming than Korean policies. Japanese policies take an entire system covering from farm to market into account. Second, Japanese policies have much attention to the agricultural organizations such as corporate, cooperatives that are eligible for using agricultural machinery. This is different from Korean policy. Thus, upland farming mechanization policy needs to set priority, and to have systemic approach. Also, upland farming mechanization policy has to be facilitated in accordance with producer organizations and their marketing strategies.
