Korea-Japan Fisheries Agreement concluded in 1965 made a contribution to the stable development of fisheries relationship for both countries until the year of 1980. From the time on thereafter a series of respectable fishery disputes occurred throughout the period of fisheries self-regulation in accordance with alteration of home and abroad conditions. And both countries marched into a cooperation era by enforcement of the new fisheries agreement from the 23 January 1999, because the Fisheries Agreement system of 1965 had many limitations to settle the fundamental fisheries problems. In this paper, the author carried out the legal interpretation, arrangement of historical facts and evaluation of actual results of the Korea-Japan Fisheries Agreement of 1965. The key contents of the Fisheries Agreement were the establishment of 12-nautical mile exclusive fishery zone and the joint-control fishery zone under the principles of maintenance of MSY for fishery resources, freedom of high seas and mutual cooperation. The legal foundation of the conclusion of the Fisheries Agreement were the San Francisco Peace Treaty of 1952 and the four International Conventions on the Law of the Sea of 1958. During the 33 years, the fisheries power of Korea made a rapid stride, on the other hand that of Japan was almost stagnated. And in the meantime, there were very important development on the international law of the sea, for instant, the settlement of 12-nautical mile territorial sea regime and the establishment of 200-nautical mile exclusive economic zone regime. Annual meetings of the Joint Fisheries Committee were not successful to fill the role for conservation of fishery resources. The Fisheries Self-Regulation Agreement concluded in 1980 was also insufficient to accept the new international regime on the law of the sea, for that reason it was terminated on 23 January 1999. But it is true that the Fisheries Agreement of 1965 made a contribution to normalization of fisheries relationship between both countries and fisheries development of Korea.

Algorithmic trading, which uses algorithms to trade financial products, has a problem in that the results are not stable due to many factors in the market. To alleviate this problem, ensemble techniques that combine trading algorithms have been proposed. However, there are several problems with this ensemble method. First, the trading algorithm may not be selected so as to satisfy the minimum performance requirement (more than random) of the algorithm included in the ensemble, which is a necessary requirement of the ensemble. Second, there is no guarantee that an ensemble model that performed well in the past will perform well in the future. In order to solve these problems, a method for selecting trading algorithms included in the ensemble model is proposed as follows. Based on past data, we measure the contribution of the trading algorithms included in the ensemble models with high performance. However, for contributions based only on this historical data, since there are not enough past data and the uncertainty of the past data is not reflected, the contribution distribution is approximated using the Dirichlet distribution, and the contribution values are sampled from the contribution distribution to reflect the uncertainty. Based on the contribution distribution of the trading algorithm obtained from the past data, the Transformer is trained to predict the future contribution. Trading algorithms with high predicted future contribution are selected and included in the ensemble model. Through experiments, it was proved that the proposed ensemble method showed superior performance compared to the existing ensemble methods.

Ancient masonry towers are regarded as among the most important historical heritage structures of the world. These slender structures typically have orthogonal and circular geometry in plane. These structural forms are commonly installed with adjacent structures. Because of their geometrical shapes and structural constraints, ancient masonry towers are more vulnerable to earthquake damage. The main goal of the paper is to investigate the seismic behavior of Erzurum Clock Tower under earthquake loading and to determine the contribution of the castle walls to the seismic performance of the tower. In this study, four three-dimensional finite element models of the Erzurum Clock Tower were developed and the seismic responses of the models were investigated. Time history analyses were performed using the earthquakes that took place in Turkey in 1983 near Erzurum and in 1992 near Erzincan. In the first model, the clock tower was modeled without the adjacent walls; in the second model, the clock tower was modeled with a castle wall on the south side; in the third model, the clock tower was modeled with a castle wall on the north side; and in the last model, the clock tower was modeled with two castle walls on both the north and south sides. Results of the analyses show that the adjacent walls do not allow lateral movements and the horizontal displacements decreases. It is concluded that the adjacent structures should be taken into consideration when modeling seismic performance in order to get accurate and realistic results.

Objective : The aim of this study is to review the historical development and current situation of Mongolian traditional medicine. Method : Systematic literature review for books, journals, governments statistics, reports on mongolian traditional medicine was carried out. Results : The theory of Mongolian traditional medicine is influenced by the philosophy and medical theories of the ancient orient such as India, Tibet and China-theories of hot and cold, principle of yin and yang and five elements. There are very unique treatments like brain tram concussion, fermented horse milk treatment as well as moxibustion, acupuncture, and blood letting. It appears that they are very closed to nomadic life. Training program of each institutes need to be standardized. Mongolian traditional medicine had been almost destroyed by the influence of communist idea from 1930s until the end of the 1980s. Since 1990, Mongolian government put much emphasis on the development of traditional medicine. And now about 3.7% of total beds is traditional medicine one and that there are six TM schools and the total number of traditional medicine in 2012 is 1696. However, there are still the lack of manpower, facilities, standardized training program and scientific research for traditional medicine. Conclusion : Mongolian traditional medicine has been developed over centuries in response to Mongolia's unique geographical and climate conditions and the lifestyles of its people and that made contribution to the health of mongolian people. However, it needs to be strengthened because there are poor infrastructure and training program.

Historical emission data for 11 polychlorinated biphenyls (PCBs) and a regional multimedia environmental model, CoZMo-POP 2, were used to predict air concentrations and congener patterns in Korea. The total emission value for South Korea was allocated to sub-provinces and cities based on their population. The spatial distribution of PCB emissions was generally correlated with that of measured atmospheric levels, suggesting that population could be a good surrogate for the intensity of PCB emission in Korea. The simulated time trends of air concentrations well reflected those of emission with a peak in the mid-1970s and insignificant levels in the 2030s. The model predicted that the contribution of volatile PCBs had increased after emission reduction iii the 1970s. This trend would continue until the early 2030s. The measured and modeled PCB levels in the 2000s were in an agreement of an order of magnitude, and their congener patterns were very similar. Consequently, despite of high uncertainty for emission estimates, the emission data for Korea used in this study is considered to be reliable. The results of this study could be compared with simulation data based on a new emission inventory to be developed by measurements in the near future.

This study tries to compare the architectural thought of Michel Foucault with that of Manfredo Tafuri in order to make clear the architectural identity as a social institution. In Michel Foucault's case, the archeology of discourse and the geneology of power were central method to understand the history of occidental society since the Renaissance. Four him, architecture is assumed as a mechanism of operation which make the power effectively radiate in th space. He thinks that a new discursive space was arranged since the 18th century in Europe, the architecture played a role to coordinate divers powers. Mafredo Tafuri, architetural historian, depends on the criticism of ideology in search of the relation between the economic system of capitalism and modern architecture and urbanism. He thinks that all architecture is an institution. And any attempt to overthrow the institution, is bound to see itself turned into a positive contribution and into an ideology, So all architectural attempts to conceal the contradiction of capitalism are negated. This different perspective on architecture exposes many points of dispute: historical periodization, disciplinary limit of architecture, understanding of Enlightenment architecture, utopia and heterotopia, etc.

Objectives: This paper was prepared in memory of Jerry Sherwood, who provided a significant contribution to the Korean environmental and occupational health fields. Methods: Rare air quality data in Seoul were gathered by Jerry Sherwood when he visited Korea in the early 1980s. $SO_2$ and TPM concentrations were measured. These air quality measurements were based on ambient stationary monitoring and indoor air quality monitoring in various locations. Measurement during transportation was also applied. Results: Ambient $SO_2$ and TPM concentrations in Seoul were very high in the early 1980s. Ambient $SO_2$ concentrations were higher at nighttime. While ambient $SO_2$ concentrations varied by location, the Guro industrial area showed high levels. When indoor sources were presented, indoor $SO_2$ concentration was higher than outdoor level. Coal briquettes were closely associated with high indoor $SO_2$ concentration. Conclusion: This paper provided valuable historical information of air quality in Seoul.

The purpose of this study is to explore the underlying causes of the development of private security in the United States. These include the increasing crime rates and fear of crime, the poor performance of public policing, the decentralization of political authority, the increase of mass private property, economic growth and increase of personal income, commodification of security, insurance companies' demand for tighter security and fear of litigation, and historical events such as World War I & II. Based on the findings of this study, it is suggested that no single factor would account for the growth of private security in the United States. In other words, the rapid growth of private security in the United States should be attributed to the interrelated influences of the factors given above. Finally, it might be the contribution of this study that the future development of private security in Korea would be guided by understanding the case of the United States because of the similarities of the developmental process in private security industry of two countries.

Discussions of world history often focus on the pros and cons of thinking on large spatial scales. However, world history also tends to employ unusually large timescales, both for research and teaching; frequently it is framed around a teleology and a series of "revolutions" which mark milestones taking humans from a very distant past to "modernity". Moreover, world history usually rejects regionally specific period markers (e.g. Renaissance), making periodization within this long timespan especially difficult. This article surveys various approaches to these problems, and shows that any of them, if treated as sufficient by itself, introduces significant distortions. It argues for a world history that highlights this problem, rather than hiding it, and which uses the need to deploy multiple timescales simultaneously to clarify the distinctive intellectual contribution of historical thinking.

This interdisciplinary study explores G$\ddot{o}$del's hermeneutics of the relationship between relativity theory and idealistic philosophy in terms of time. For G$\ddot{o}$del, Einstein's contribution to the physical realization of idealistic philosophy would be remarkable. We start with a historical background around G$\ddot{o}$del's paper for Einstein(1949a). From the perspective of G$\ddot{o}$del's cosmology, the second part addresses the relative nature of time, and the next then investigates the rotating model of universes. G$\ddot{o}$del's own results show that the temporal conditions of relativity and idealistic philosophy are satisfiable in the mathematical model of rotating universes. Thus, it could be asserted to travel into any region of the past, present or future, and back again.
