In the early 1990's, international security environment bring on the change. So each countries should have renewed the defence policy. The developed countries make efforts to keep the superiority of military industry with an high technology and huge capital. One of the efforts is the defence industry exhibitions for the management performance regarded as the marketing strategic principal method. The result of the opening exhibitions has been studied by research papers and treatises. A exhibitions' goal is different from an it's characteristic, type, industry, participator, institution and participating nation. An enterprise's management performance is runs as follows. First, an exhibitions participation activation has an effect re-participation following the satisfaction. Second, an exhibitions participation activation contributes to be on sale promotion, The result of the exhibitions participation is classified with sale performance and non-sale performance. The third, an exhibitions participation activation contributes to the effective company management. The huge fund advertisement is a financial burden, but a exhibitions takes effect one-fifth economical retrenchment. Accordingly, this study researched the exhibition participation choice properties, an exhibitions participation activation properties and investigated the Korea defence industry's income statement, balance sheet, growth ratios, profitability ratios, productivity ratios, stability ratios which were substitute for the enterprise's management performance through the exhibitions participation costs and the number of times.

This study aims to investigate droughts from the magnitude perspective based on the SPI (Standardized Precipitation Index) and the theory of runs applicable to quantitative analysis of drought in South Korea. In addition, the dry spell analysis was conducted on the drought history in the five major river basins of South Korea to obtain the magnitude, duration and severity of drought, and the quantitative evaluation has been made on historical droughts by estimating the return period using the SDF (Severity-Duration-Frequency) curve gained through drought frequency analysis. The analysis results showed that the return periods for droughts at the regional and major river basin scales were clearly identified. The return periods of severe drought that occurred around the major river basins in South Korea turn out to be mostly 30 to 50 years with the years of the worst drought in terms of severity being 1988 and 1994. In particular, South Korea experienced extremely severe droughts for two consecutive years during the period between 1994 and 1995. Drought in 2014 occurred in the Han River basin and was evaluated as the worst one in terms of severity and magnitude.

In any military services, young leaders are superiors to another and the leaders must be equipped with not only command and control(C2) and management capabilities but with a skill set that addresses their service members' problems and hardships throughout a counseling approach. These young leaders other than regular professional counselors are wearing dual hats as a commander and a counselor to address their service member's issues. There are couple of hours to give a lecture about counseling during the basic training course, however, we noticed that there are some limitations to cover up the uniqueness of counseling during the course, since we cannot rule out the unique vertical situation within military system that runs by its hierarchy. Therefore, we developed education program in order to enhance commander's counseling skills, refined the program with thorough review and commentary by professions and military commanders, and provided 10 events of program to the young leaders. As a result, the leaders scored high on self-effectiveness, communication skills, and counseling development-level. If we adjust minor changes to the program, it will be the outstanding program to improve young leaders' counseling capability.

The overemphasis of the priority of reason over will runs the risk of resulting in intellectual determinism. On the contrary, it is also unfair to underestimate the role of reason in Saint Thomas Aquinas' theory of the free will to avoid intellectual determinism. For, according to Thomas, "the will inclines to the good, insofar as it is an appetite, and it follows the judgment of the reason in the pursuit of the good, insofar as it is a 'rational' appetite." It is the objective of this article to show that, for Thomas, the idea of the free will is not contradictory to that of the will's following the judgment of reason. For this purpose, it is decisive to adequately evaluate the role of reason in Thomas's theory of the free will. This article therefore proves that in principle Thomas argues the priority of the will over reason as well as the freedom of the will, and that he nevertheless recognizes the role of reason which precedes the choice of the will by making the second-level judgment even when the will chooses not to follow the first-level judgement of reason. It is entirely up to the will to follow the judgement and order of reason or not. It explains the freedom of the will. But 'not to follow reason' is contradictory to the essential determination of the will as the 'rational' appetite. For from the will's not following reason, wrong-doing follows; the human act which does not conform to reason. This article therefore argues that for Thomas, the 'true' liberty of the will corresponding to its determination as the rational appetite consists in its following the rule and order of reason, not in acting against the judgement of reason.

The purpose of this study is to predict agricultural reservoir storage rate (RSR) in a month. This algorithm was developed by multiple linear regression model (MLRM) which included the past 3 months RSRs data and the future climate change scenarios. In order to improve use of predicted RSR, this study need the severe criteria in terms of drought. So, the predicted RSR was indexed as the 3 months reservoir drought index (RDI3) and then it was disaggregated into drought duration, severity, and intensity. For the future RSR estimation by climate change scenarios, the 6 RCP 8.5 scenarios of HadGEM2-ES, CESM1-BGC, MPI-ESM-MR, INM-CM4, FGOALS-s2, and HadGEM3-RA were used in three future evaluation periods (S1: 2011~2040, S2: 2041~2070, S3: 2071~2099). The future S3 period of HadGEM2-ES scenario which has the biggest increase in precipitation and temperature showed the largest decrease to 60.2% among the 6 scenarios compared to the historical RSR (1976~2005) 77.3%. In contrast, INM-CM4 scenario which has smallest changes in precipitation and temperature in S3 period showed the smallest decrease to 72.8%. For the CESM1-BGC and MPI-ESM-MR, FGOALS-s2, and HadGEM3-RA, the S3 period RSR showed 72.6%, 72.6%, 67.4%, and 64.5% decrease respectively. The future severe drought condition of RDI3 below -0.25 showed the increase trend for the number and severity up to -2.0 during S3 period.

This study aims to conceptualize characteristics of the Korean traditional dance, and to categorize and analyze the recognition of experience of passing down education of Seungmu(Buddhist Dance), Salpurichum(Exorcism Dance) and Taepyeongmu(Dance of Peace). Dividing into groups of two: an experienced person twenty years or more in the Korean dance and a person who completed the traditional dance three years or more, three groups were selected. We connected the characteristics of the traditional dance experienced in passing down education with the recognition experience in the training courses. Categorizing thematically the process and the recognition of experience in the passing down education program, we attempted mutual group discussion and inductive area analysis on the basis of in-depth interview, tutorial discussion and analysis contents. As a result of this study, first, the characteristics of the Korean traditional dance that graduates of the program by repertory empathize were the experience of the sinmyung(the excess of mirth) and improvisation, the supreme self-controlling beauty and the best beauty of expression. Second, the recognition of experience in the passing down education program runs as follows: Interacting in the centre of the process, new education system for transmission, and formation of social discourse for appreciation. Conclusionally, the experience and the new vision for transmission of passing down education of the traditional dance are required to be based on the appreciation of the rationality of mutual communication and recognition of experience.

As the IoT-based hyper-connected society grows, public-key cryptosystem such as RSA is frequently used for encryption, authentication, and digital signature. Public-key cryptosystem use very large (safe) prime numbers to ensure security against malicious attacks. Even though the performance of the device has greatly improved, the generation of a large (safe)prime is time-consuming or memory-intensive. In this paper, we propose ET-MR and ET-MR-MR using Euler sieve so it runs faster while using less memory. We present a running time prediction model by probabilistic analysis and compare time and memory of our method with conventional methods. Experimental results show that the difference between the expected running time and the measured running time is less than 4%. In addition, the fastest running time of ET-MR is 36% faster than that of TD-MR, 8.5% faster than that of DT-MR and the fastest running time of ET-MR-MR is 65.3% faster than that of TD-MR-MR and similar to that of DT-MR-MR. When k=12,381, the memory usage of ET-MR is 2.7 times more than that of DT-MR but 98.5% less than that of TD-MR and when k=65,536, the memory usage of ET-MR-MR is 98.48% less than that of TD-MR-MR and 92.8% less than that of DT-MR-MR.

The problem of freedom is inseparably related to human life. It makes this not to be regarded as a problem restricted to the professional domain of ethics. It suggests rather that the problem of freedom is intimately connected with the philosophical groundwork for discussing the future direction of society, culture and science, and its regulative idea, a philosophical discussion which comes up inevitably with various social, economic and political problems, and problems related to the spirit of law. In this view, when we want to explain the problem of freedom as a fundamental one in reference to future direction of humanities and to find out a solution to this, our research only in accordance with the approach of history of philosophy runs into difficulties. The reason is that the problem of freedom has nowness together with historicity. Finding this problem to be a present one in our concrete human life, we can discuss it more meaningful under the methodological frame changed and developed by philosophical reflections since the modern age. And here I think a culturalistic approach reinterpreting hermeneutic insight and pragmatistic context methodologically can provide a pertinent clue for a theoretical work to investigate the problem of freedom and to find a solution to that because this approach considers historicity and nowness. For this purpose analysing truth intersubjectively and understanding freedom critically, this article tries to reconstruct symbolic interpretation and the concept of self constructed in community of language and action as a cultural horizon of freedom.

This article aims to investigate the studies of Yi Xue Qi Meng(易學啓蒙) performed by the researchers of Neo-Confucianism in Ki Ho region in later Chosun period. Philologically speaking, these studies were mainly performed by Han Won Jin and his colleagues. While the study of Yi Hwang(李滉)'s Qi Meng Zhuan Yi(啓蒙傳疑) performed by the researchers of Toegye(退溪) School lasts from the end of the sixteenth century to the nineteen's century, the Ki Ho(畿湖) scholars' study of Yi Xue Qi Meng are centered in the eighteenth century and hardly any significant work on this text is found before and after this century. In order to single out the distinctive features of Ki Ho School of Neo-Confucianism, this article examines three subjects the Ki Ho scholars delved into: (i) their theory of Tai Ji(太極), (ii) their theory of He-Tu(河圖) and the formation of eight trigrams, and (iii) the so-called Wu Wei Xiang De Shuo(五位相得說) discussed in one of the sections in Yi Xue Qi Meng titled the Source of He-Tu and Luo Shu[本圖書]. The Ki Ho scholars are remarkable in interpreting Tai Ji in Yi Xue Qi Meng in the context of the theory of Li-Qi and the theory of human nature. There are differences in opinion among the Ki-Ho scholars with regard to the relation between He-Tu and the formation of eight trigrams. Eventually, they withhold Zhu Xi(朱熹) and Hu Fang Ping(胡方平)'s attempt to synthesize He-Tu, the rectangular diagram of Fu Xi(伏羲)'s eight trigrams, and the circular diagram of Fu Xi's eight trigrams into one single principle. Han Won Jin tries to explain the relation between He-tu and the formation of eight trigrams in terms of the relation between He-Tu and the circular diagram, and his attempt is widely supported by his colleagues. This theory runs counter to traditional model of explaining truth. My conjecture is that such academic trend is further developed by the defenders of Practical Learning such as Hong Dae Yong(洪大容), who vigorously reject traditional system of truth and science, and that it partly explains why the study of Yi Xue Qi Meng ceases in the nineteenth century.
