To discuss whether we have credible estimations about historical surface temperature evolution since industrial revolution or not, present study investigates consistencies and differences of averaged surface air temperature since 1900 between the multiple data sources: Hadley Center Climate Research Unit (HadCRU4) surface air temperature data, ECMWF 20 Century Reanalysis data (ERA20CR), and NCEP 20 Century Reanalysis data (NCEP20CR). Averaged surface temperatures are obtained for the global, polar (90S~60S, 60N~0N), midlatitude (60S~30S, 30N~60N), tropical (30S~30N) region, separately. From the analysis, we show that: 1) spatio-temporal inhomogenity and scarcity of HadCRU4 data are not major obstacles in the reliable estimation of global surface air temperature. 2) Globally averaged temperature variability is largely contributed by those of tropical and midlatitude, which occupy more than 70% of earth surface in area. 3) Both data show consistent temperature variability in tropical region. 4) ERA20CR does not capture warm period over Arctic region in early 1900s, which is obvious feature in HadCRU4 data. Discrepancies among datasets suggest that high-level caution is needed especially in the interpretation of large Arctic warming in the early 1900s, which is often regarded as a natural variability in the Arctic region.

본 논문은 '미중관계의 전개와 현안문제 및 시사점을 분석하기 위한 것이다. 초기 및 적대적 대결기의 미중관계, 미중접근 관계정상화기 및 1980~90년대 미중관계, G2시대 개막후 2010년대 중반까지의 미중관계, 트럼프-시진핑시대의 미중관계와 주요현안과 시사점을 살펴본 후 결론을 도출해본 것이다. 지난 30여 년간의 중국의 급속한 성장은 기존의 미국중심의 단극적 국제질서를 변화시키며 양국간의 경쟁을 촉발시키고 있다. 미국과 중국은 전략 경제대화'를 정기적으로 개최하는 유일한 국가가 되었고, 주제 역시 양자간의 관계뿐만 아니라 글로벌 이슈까지 논의하는 나라로 발전해왔다. 미중협력 갈등의 현안문제는 양국관계는 물론 글로벌 이슈를 망라하고 있다. 예컨대 남중국해, 북핵과 사드, 통상 금융질서, 대만문제 등이 바로 그것이다. 미중갈등은 남의 일이 아니라 한국의 외교 안보 경제에도 직결되는 문제이다. 우리는 미중관계에 있어서 '코리아 패싱(Korea passing)'이 나오지 않도록 튼튼한 한 미 안보공조관계를 유지 강화해 나가는 한편, 한 중 경제협력관계도 조화롭게 추진해 나가는 헤징전략이 요구된다.

This thesis examines the problems faced in the electronic trade platform for which improvements are necessary, and suggests various ways of overcoming those problems. Practical implications regarding the advancement of Korea's u-TradeHub system are as follows. First, from the technical and legal aspects, to make up for a lack of support systems for spread of users, it is required to promote customized advertising strategies through Ministry of Knowledge Economy and establish a global certification system. Second, document standardization and digitalization should be achieved in advance to make the documents distributed through the e-Trade platform in a seamless manner. Furthermore, an ongoing global network development project should be promoted through the e-Trade platform to achieve standardization. Third, from the operational aspect, it is important to maintain an integrated and systematic relationship with related organizations. Because vertical integration among logistics service providers and GSCM are enabled through the e-Trade platform, it is necessary to standardize global network-based linkage and operating systems.

In order to develop high value fashion culture products capable of reaching the global market, this study developed the original traditional clothing design of Northeast Asian countries according to a global perspective. This study applied the structural formality of traditional clothing to fashion cultural products. This study developed designs using Deel of Mongolia, Makap of China Korean Dang-ui / Dan-ryung, and Haori of Japan. The research methods are theoretically examined using literature on traditional clothing in Northeast Asia. First, it designed a shirt design using Adobe Illustrator CS6 and created a pattern with the Yuka program as well as applied CLO 5.0 (a 3D virtual dressing system from CLO Virtual Fashion Co.). A survey was also conducted on individual interest for the developed fashion cultural products. The design method obtained various design effects by applying the method of adding point detail parts of the clothes to the shirt that represented each country among their traditional clothes. This research can be used as basic data for the global fashion cultural products market that can contribute to maintaining the originality of each country in the global era, expanding tourism income to succeed and develop culture and tradition.

Much of the behavior of doctors reflects the influences from the social, cultural, historical, and economic environment of the time. Therefore, it is very important for future doctors to understand the practice environment in an ever changing world. Traditionally, doctors' competence has been based on the doctor-patient relationship. However, the social practice of medicine in the contemporary era asks future doctors to have social competencies, which often are defined as non-clinical competencies. As a global project, the World Federation for Medical Education has urged every country to define the future role of doctors to encompass global roles based on the duty toward and value of clinical as well as non-clinical competencies. In the past four years, Korean medical professional societies have coordinated to set forth the global role of Korean doctors. Five domains of clinical competence, professionalism, social accountability, communication and collaboration, and education and research have been chosen. The current version of the "global role of Korean doctors" can be used not only for the common objectives of medical education, but also for translating into the competencies of doctors that can be achieved through life-long learning. If we all want to improve medical education in order to produce more qualified and competent doctors as the public desires, then it may be the most urgent task to produce doctors who are equipped with social competencies to persuade, negotiate, and engage in constructive dialogues with society for better health care for a better society.

We present an update on our proposal that during the 'quasar era' (1.5 $\le$ z $\le$ 3), powerful radio galaxies could have played a major role in the enhanced global star-formation, and in the widespread magnetization and metal pollution of the universe. A key ingredient of this proposal is our estimate that the true cosmological evolution of the radio galaxy population is likely to be even steeper than what has been inferred from flux-limited samples of radio sources with redshift data, when an allowance is made for the inverse Compton losses on the cosmic microwave background which were much greater at higher redshifts. We thus estimate that a large fraction of the clumps of proto-galactic material within the cosmic web of filaments was probably impacted by the expanding lobes of radio galaxies during the quasar era. Some recently published observational evidence and simulations which provide support for this picture are pointed out. We also show that the inverse Compton x-ray emission from the population of radio galaxies during the quasar era, which we inferred to be largely missing from the derived radio luminosity function, is still only a small fraction of the observed soft x-ray background (XRB) and hence the limit imposed on this scenario by the XRB is not violated.

Cultural heritage passing down to posterity is a global concern. But there are many culture heritage that not remained to now disappeared by various disasters. It is told that disaster is learnt from disaster. The most fundamental task in disaster prevention is to collect and analyze cases of accidents so as not to repeat a disaster. In other words, an analysis of various disaster-related materials and their countermeasures in the Joseon period is an actual condition-based phenomenological methodology used to prevent disasters at cultural properties today. In this context, it is important to collect histories of disasters in the Joseon period, to extract disaster-related historical data and to categorize the data to build a disaster literature database. This study has produced [Database of Disasters in the Joseon Era], a collection of articles on fire outbreaks based on The Annals and The Daily Records belonging to the Memory of the World. On the basis of this chronology, human and property damages caused by fires in Joseon have been examined, identified by districts, as well as disaster technologies, have been analyzed. It has also built disaster vulnerability maps in the Joseon Dynasty Era.
