This paper has two goals: first, I will analyze the current research trend of studying the Nosa School, which is composed of Ki Jeongjin(1798~1879) and his students and then, provide with some tasks we have to solve. The Nosa Studies, which I suggest here, means the one that the scholarship and thought of Ki Jeongjin, one of the six masters and the representatives of neo- Confucianism in late Choson Korea, and all kinds of academic achievements, which had been succeeded and established by his students. Their diverse activities as well as scholarship play crucial roles in both modern Korean Confucianism and Dao Studies in late Choson Korea. Ki's core thought is a conclusion of various issues, which had been raised since Korean Confucianism of Toegye and Yukgok. Their diverse activities kicked into high gear after Ki's death can be understood as one of remarkable cases, which was how to be transformed by encounters with realities in modern Korea. Especially, some controversies and responses to practical issues that linked with their philosophical values of the Nosa Studies in Kiho school in early twentieth century will be a criterion to shed light on the identity of Korean Confucianism today. Thus, I will summarize the content of researches on the Nosa Studies, which begins to appear in the early-mid twentieth century, through an overview of the Nosa Studies, examine research results by dividing part by part, and provide with some prospects and tasks, which are based on what I mention above.

For this research, the trajectory of a projectile was simulated via the multibody dynamics analysis of a self-propelled mortar. The dynamic model was composed of a mortar model and a vehicle model, and was simulated using the RecurDyn program. Interior ballistic was applied to the mortar model, and exterior ballistic was conducted by Matlab using the simulation results of the interior trajectory. Through repetitive Monte-Carlo simulations, the accuracy of the mortar was analyzed by considering variations in the aiming angle and vehicle dynamic response.

There are many methods to calculate steady-state flowrate in a large water distribution system. Linear method which analyzes continuity equations and energy equations simultaneously is most widely used. Though it is theoretically simple, when it is applied to a practical water distribution system, it produces a very sparse coefficient matrix and most of its diagonal elements are to be zero. This sparsity characteristic of coefficient matrix makes it difficult to analyze pipe flow using the linear method. In this study, a graph theory is introduced to water distribution system analysis in order to prevent from producing ill-conditioned coefficient matrix and the technique is developed to produce positive-definite matrix. To test applicability of developed method, this method is applied to 22 pipes and 142 pipes system located nearby Taegu city. The results obtained from these applications show that the method can calculate flowrate effectively without failure in converage. Thus it is expected that the method can analyze steady state flowrate and pressure in pipe network systems efficiently. Keywords : pipe flow analysis, graph theory, linear method.

Objectives Lee Je-Ma's Sasang-philosophy that was discussed in Donguisusebowon is Maeumron and Qi-philosophy. Sasang-philosophy has a direct origin to Mencius, which discusses the Maeumron of Confucianism. Therefore the relationship between Maeumron of Donguisusebowon and Mencius Chapter 3 will be examined. Methods Materials and references were collected about the literature survey. Lee Je-Ma's books such as Donguisusebowon, Gyeokchigo and a book of Confucianism including the Mencius. Results and Conclusions Hoyeonjiqi in 'Sadanron' of Donguisusebowon encompasses the Qi of metaphysical personality and physiological Qi, and it can be seen that it is the Qi that fuses body and mind together. Benevolence, righteousness, propriety and wisdom are directly linked to the personal mind of Sasangin. Unlike the mencius's four clues of virtue, the Sadan is discussed in terms of the large and small organs in four constitution such sa lungs, spleen, liver, and kidneys. Next, In the relationship between Taesim of 'Whoakchungron' and greed of Mencius, if discuss a relationships between 'I understand language' and Taesim, Deceptive speech connects with the dogmatism of Soeumin, Licentious speech connects with indulgence of Taeumin, Crooked speech connects with laziness of Soyangin and Evasive speech connects with selfishness of Taeyangin. Also in the relationship between taking delight gladness without real cause idleness arrogant and Taesim, taking Delight connects with the dogmatism of Soeumin, Gladness without real cause connects with selfishness of Taeyangin, Idleness connects with laziness of Soyangin, and Arrogant connects with indulgence of Taeumin. The next thing, people of Four types of 'Gwangjeseol' coincide with Mencius. Also Love benevolence and enjoy goodness, Envy benevolence and jealous talent in the 'Gwangjeseol' are able to find the source directly in Mencius.

The poetry of Haseo Jo Gyeong is first characterized by its fantasy content with mysterious and strange beings such as mountain wizards, gods of flowers, ghosts, Jujos and dragons. Such works imply the huge gap between his political ideal of Neo-Confucianism and the reality of society and are expressions of his resulting sorrow. Of course, he did not just look at reality pessimistically. Like other Neo-Confucianism scholars, he used the symbol of "spring" in his poems, which indicates that he did have optimistic belief in the world in spite of despair. In his poems, the symbol of "spring" implies the political world where the noble man grabbed the power and the sinister groups were extracted or the world where the political ethics of Neo-Confucianism was implemented. His works depicting the essence of natural objects, mountains, and rivers exhibit the characteristics of his poetry more clearly. He described the law of the universe behind natural objects and the vibrant aspects of natural objects by depicting their movements in a clear and sharp manner. Unlike the old Neo-Confucianism scholars that often created poems on the topic of acquirement of natural law and nature, he expanded his poetic world in a direction of revealing the secrets of objects. His works describing the spirit of mountains and rivers are especially noteworthy in that they implied a life attitude of moving forward in an deteriorating world bravely by manifesting strong and dynamic power. Paying attention to the secrets of natural objects, Haseo displayed his life ideal in richer ways by painting the new forms of ume flowers. Unlike the old ume flowers poems in the past, his ume flowers poems present ume flowers as ascetics that obtained truth, men of virtue that inspired contemporary people, or retired gentlemen that revealed the profound secrets of nature. While it is unique that he manifested the forms of ume flowers in ascetics and men of virtue while perceiving the dark reality of society, it is more noteworthy that he described ume flowers as the beings revealing the profound secrets of nature. It was the expression of his yearning for an innocent personality and his fear for losing the personality, clearly depicting a human form of his ego. He created a more human and realistic personality ideal by embracing the contemporary thinking based on the profound secrets of nature in his Dohak poetry[道學詩], which is a significant achievement in that it showed new changes to Dohak poetry in the 18th century.

Studying on the history of korean ancient poetry, we come in contact with a series of verses which 'Jejisarim's Kangho Shijo'. In the 16th century are the representative works among them. Sarim were involved in the domestic discords so that they brought about severe party strifes after all. 'Jejisarim's Kangho Shijo' profoundly dealt with the various problems concerning nature and human beings. Lee, Hyunbo and Lee, Whang are closely related with the philosophical attitudes of Confucianism. After this, Kyun, Homun and Jang, Kyungse can be largely summarized as the dual theory of reason and spirit. From the standpoint of natural principles, the epistmology of Confucianism. the theory of reason has characterized by ideality and reality. It can be said that the problem of harmonizing and uniting nature with human beings was solved in the unity of space and man. 'Jejisarim's Kangho Shijo' in the 16th century prominently express not only the courses of character cultivation but also the pride and close relationship between nature and human beings. We can say that 'Jejisarim's Kangho Shijo' in the 16th century are divided into both types of the conservative idealism and the reformative realism in the Jejisarim. Kangho Ship. the epistmology of Confucianism nature and human beings. ideality and reality political status and that such ships can be separated into types ideality and reality in the philosophical context.

Cho Gwang-jo(趙光祖, 1482-1519) was the moralist who had the purest conscience and aimed the devoted politics among many fellow Confucianists of Chosun Dynasty. He even criticized his teacher who was in his late forty years for not being able to control his emotions when he was just a teenager. That is to say, he was the one who have kept his cold reasons for entire life. Nevertheless, as mentioned before, Cho Gwang-jo was very faithful to his emotions and also very honest. We find that he was definitely emotional. He demanded to change the relationship between the king and the courtier to the one between the father and the son with humane communication. He expressed his mind and emotion he had used to have at the moment of his death: he loved his king just as he loved his father. However, the king, Joongjong, was indifferent at the human's emotion as if he was a senseless figure. That was the saddest frustration and grief he had. However, his grief did not remained just as the mere grief but again survived as the hope for the survivors and descendants with the big echo. In this respect, his gried did not just end as the grief but it can be said that it even revived itself as the strength and courage. Then, Cho Gwang-jo's life as a human being was never a failure. Moreover, his grief and agony did not just remained as the vain emotion and sadness.
