  • Global air temperature has risen by $0.6^{\circ}C$ over the last one hundred years due to increased atmospheric greenhouse gases. Moreover, this global warming trend is projected to continue in the future. This study was carried out to evaluate spatial variations in rice production areas by simulating rice-growth and development with projected high resolution climate data in Korea far 2011-2100, which was geospatially interpolated from the 25 km gridded data based on the IPCC SRES A2 emission scenario. Satellite remote sensing data were used to pinpoint the rice-growing areas, and corresponding climate data were aggregated to represent the official 'crop reporting county'. For the simulation experiment, we used a CERES-Rice model modified by introducing two equations to calculate the leaf appearance rate based on the effective temperature and existing leaf number and the final number of leaves based on day-length in the photoperiod sensitive phase of rice. We tested the performance of this model using data-sets obtained from transplanting dates and nitrogen fertilization rates experiments over three years (2002 to 2004). The simulation results showed a good performance of this model in heading date prediction [$R^2$=0.9586 for early (Odaebyeo), $R^2$=0.9681 for medium (Hwasungbyeo), and $R^2$=0.9477 for late (Dongjinbyeo) maturity cultivars]. A modified version of CERES-Rice was used to simulate the growth and development of three Japonica varieties, representing early, medium, and late maturity classes, to project crop status for climatological normal years between 2011 and 2100. In order to compare the temporal changes, three sets of data representing 3 climatological years (2011-2040, 2041-2070, and 2071-2100) were successively used to run the model. Simulated growth and yield data of the three Japonica cultivars under the observed climate for 1971-2000 was set as a reference. Compared with the current normal, heading date was accelerated by 7 days for 2011-2040 and 20 days for 2071-2100. Physiological maturity was accelerated by 15 days for 2011-2040 and 30 days for 2071-2100. Rice yield was in general reduced by 6-25%, 3-26%, and 3-25% per 10a in early, medium, and late maturity classes, respectively. However, mid to late maturing varieties showed an increased yield in northern Gyeonggi Province and in most of Kwangwon Province in 2071-2100.

  • Objective : This study aims to review research trends in driving rehabilitation for the disabled in South Korea since 2000 suggesting research directions for clinicians and researchers. Methods : Fifty eight articles in 16 journals listed in accredited or candidate journal lists of National Research Foundation of Korea from January, 2000 to December, 2016 were reviewed. 'Driving rehabilitation' and 'driving for disabled' were used as search terms. Descriptive statistics were used to classify articles according to study methodology, levels of evidence, study participants, research topics, and academic associations or official journals. Results : Fifty percent of analyzed researches have been published since 2012. Twenty-two studies (37.9%) were published as group comparison and correlational research. Only seven studies (12.1%) were included in evidence level I. There were 19 studies (38.8%) conducted with brain-injured patients among 49 studies including participants. The Korean Society of Occupational Therapy Journal, having published 15 studies (25.9%) about driving rehabilitation, ranked first among the analyzed journals. In research topic, 15 (25.9%) studies were performed about clinical evaluation. Conclusion : The present study showed that the quality of driving rehabilitation-related studies has been increasing, but more intervention-based researches need to be carried out and it is also necessary to carry out various researches in related fields in order to establish efficient driving rehabilitation in Korea.

  • This research aims to generalize the thoughts of military science of the intellectuals through the books on military arts and science, which were published in the early Joseon Dynasty. In the early Joseon dynasty, it was in a position to establish the foundation in the new monarch internally, and, at the same time, to overcome foreign powers on both northern and southern borders externally. Thus, the books on military arts and science should have to be published under a premise of such situations. Accordingly, the books on military arts and science of those days took account of political stability having reflected the activities not only as the founder of Joseon but also as the military officer in the late Goryeo along with the books' own purpose to found military arts and sciences. The books on military arts and science that published in the early Joseon Dynasty were written mostly based on Chinese military books and its annotations, except some descriptions of the history of war. However, the intellectuals at that time endeavored to redefine military arts and science from the perspective of Confucianism having evaluated Chinese military science books that were biased to boost Machiavellian tactics. As a result of this, the geographical distinctions between China and Korea were the start of an argument for the military arts and science. There were also disputes over the relationships between the military science and the Yin-Yang School, and between the military science and Confucian school. Organizing our country's own history of war for the first time in the early Joseon Dynasty is worth for putting a high evaluation. However, it cannot help but to point out the limits of the books that there are noticeable descriptions about the factors related to toadyism, and that there are no descriptions about the wars against Japanese raiders. The books on military arts and science in the early Joseon Dynasty put emphasis on the commander's leadership that should be good at both literary and martial arts, as well as the harmony in military-to-military relations. After all, the intellectuals in the early Joseon Dynasty had linked the military arts and science to the sages of Confucian school under a premise that scholarship is to be used in combination with martial arts. And, as the nexus between the two, they noted the items of virtue, such as humaneness and righteousness (仁義); ritual and music (禮樂); loyalty and filial piety (忠孝); three fundamental principles (三綱); five moral disciplines (五倫). It can be said that this point is the typical features of the military arts and science in the early Joseon Dynasty, which cannot be found in Chinese military classics.

Freud's Moses-study and the Principle of Mythological Hermeneutic: Its Political Theological Interpretation Through Jan Assmann's Theory of Cultural Memory (프로이트의 모세-가설과신화해석학의 원리: 얀 아스만의 문화적 기억이론을 통한 정치신학적 해석)

  • The study of Freud's Moses and the background of the establishment of monotheism has become a subject of attention in the new atmosphere of the spreading of political theology and the recent rediscovery of Egyptology. This paper examines the publishing background and intentions of Freud's last book, Moses and Monotheism. And it will emphasize the fact that the Moses-Egyptian theory and his criticism of monotheism hid political theological intentions to prevent the spread of anti-Semitism in Nazi Germany. According to the Egyptologist Jan Assmann, there is a difference in that Moses' Judaism is monotheism, but Akhenaten's Aton-religion is a cosmotheism, and while Freud emphasizes Moses the 'historical figure' of that name, Assmann refers to Moses as a 'mnemohistorical figure.' Just as Freud said that the source of Jewish hatred is in Moses himself who established monotheism, Assmann argues also, monotheism is based on the so-called "Mosaic distinction" that distinguishes between true religion and false religion, thus it is possible to dismantle oppression and violence through the abolition of the Mosaic distinction. Assmann estimates that Freud had a clear stance to stop the spread of anti-Semitism as "the most explicit opponent of the Mosaic distinction." While anti-Semitic hatred spread to Christians in the Nazi era, Freud regards the real founder of Christianity, a jew Paul, as both a "Judaism destroyer" and a "successor to Judaism." At this point, Taubes began to see Paul's theology from a political theological point of view, and Assmann succeeded it. The "historical Moses" described by Freud are not "Prophet Moses" but "Moses as lawmaker and political reformer", and Jewish hatred has arisen in his distinction. Thus, Freud's monotheistic criticism as "disintegration by historical reduction"(Nietzsche) has political theological power. Just as Taubes interpreted Paul as a political theologian, Assmann found political theological elements in Freud's criticism of monotheism.

  • This article focused on the meaning of the 1979 Moon Treaty and its future. Although the Moon Treaty is one of the major 5 space related treaties, it was accepted by only 11 member states which are non-space powers, thus having the least enfluences on the field of space law. And this article analysed the relationship between the 1979 Moon Treay and 1967 Space Treaty which was the first principle treaty, and searched the meaning of the "Common Heritage of Mankind(hereinafter CHM)" stipulated in the Moon treaty in terms of international law. This article also dealt with the present and future problems arising from the Moon Treaty. As far as the 1967 Space Treaty is concerned the main standpoint is that outer space including the moon and the other celestial bodies is res extra commercium, areas not subject to national appropriation like high seas. It proclaims the principle non-appropriation concerning the celestial bodies in outer space. But the concept of CHM stipulated in the Moon Treaty created an entirely new category of territory in international law. This concept basically conveys the idea that the management, exploitation and distribution of natural resources of the area in question are matters to be decided by the international community and are not to be left to the initiative and discretion of individual states or their nationals. Similar provision is found in the 1982 Law of the Sea Convention that operates the International Sea-bed Authority created by the concept of CHM. According to the Moon Treaty international regime will be established as the exploitation of the natural resources of the celestial bodies other than the Earth is about to become feasible. Before the establishment of an international regime we could imagine moratorium upon the expoitation of the natural resources on the celestial bodies. But the drafting history of the Moon Treaty indicates that no moratorium on the exploitation of natural resources was intended prior to the setting up of the international regime. So each State Party could exploit the natural resources bearing in mind that those resouces are CHM. In this respect it would be better for Korea, now not a party to the Moon Treaty, to be a member state in the near future. According to the Moon Treaty the efforts of those countries which have contributed either directly or indirectly the exploitation of the moon shall be given special consideration. The Moon Treaty, which although is criticised by some space law experts represents a solid basis upon which further space exploration can continue, shows the expression of the common collective wisdom of all member States of the United Nations and responds the needs and possibilities of those that have already their technologies into outer space.
