This study, which explores recent and modern Confucianists’ literary works and the reflection of reality in it, is a sort of a trial study for a heterogeneous field of modern Sino-Korean literature. The creative works of 20th century Confucianists must be one of the parts which construct the whole Korean literature and literary thought. The problem of Chinese character used in these works is not so important for understanding the whole aspect of Korean literature. This study focuses on three writers:Jeong, Gi-Nool and Jeong, Poong-Seop senior and junior, and Seo, Sang-Tae. Due to their poverty, Mr. Jeong Sr. and Jr.’s poetry and prose could be published tens of years after their deaths. They studied Confucianism, that had rapidly been weakened through the abolition of the civil service examination and the ruin and restoration of our country’s independence, and that had to yield the summons of the times to the new learning. However, unfortunately, they couldn’t display their talent because of individual, familial, domestic problems, though they had been born with special poetic talents. As a result, their literary feelings couldn"t help value falling into desperation and sadness. Unlike them, Seo, Sang-Tae could continue his study without giving up his belief and without using knowledge as a means of living from hand to mouth. Furthermore, due to his strict personality and worldly wisdom, he could keep on improving himself without falling into worldly pleasure. He believed that it was his own duty to keep the value of Confucianism, and that filial duty is the absolute value regardless of change of the times. He thought, wrote, read about filial duty, and practiced it himself. In short, the Confucianists of recent and modern times in Korea showed two different ways of reaction to reality. One is the way to keep on deploring and wandering being unable to adapt themselves to the complicated reality. The other is the way to keep and follow the traditional value adapting to reality. These several ways of living can be used as an effective means to observe the life of the intellectuals at that time, even though they are particular examples extracted from some intelligent people of rural areas.

This article is about how the sea is realized in novels of the time of enlightenment. The sea in classic novels was a natural space on that human``s will and objective were not reflected. The sea in Pyeoherok was merely a dangerous space that influenced on human survival. Until Choseon Dynasty, the sea in narrative literature was just a natural space that the human element was entirely excluded. However the situation of surrounding Korean narrative literature has been rapidly changed by the foreign culture and the trend of enlightenment. Accordingly, the press started to emphasize the ``travel`` for the purpose of understanding foreign countries from the end of 19th century. This thought has been actively reflected on novels from 20th century. In the course of being reflecting, the sea was turned to a concrete and actual space that was closely related in human life. In this point of view, one of the important characteristics of novels in the time of enlightenment must be the discovery of sea as a civilized space. Yeo-yeong-ung and Seo-he-pung-pa were examples of those novels. Yeo-yeong-ung focused on the course that an island in the middle of sea was developed from primitive and unenlightened country into a powerful nation. Seo-he-pung-pa was not only concerned with the sea itself to arouse an exploration or an adventure, but also with the building and operating of modern ship. That is to say, the former showed an interest on a political and military value of the sea, and the latter on an economic value of the sea. Therefore, the two novels had a literary significance in terms that faithfully reflected the spirit of the time of enlightenment and innovatively expanded the spatial background of Korean novel.

Customer may evaluate the vehicles by design, engine performance, advanced technology and acceleration etc. However, even though the vehicles have good function, these criteria will not meet each customer's propensity. For that reason, we should evaluate the vehicles by the factor what customers commonly feel, not by their propensity based on superficial source. In the meantime, the common factor is appeared by customer's direct driving experience. In other words, it is not the customer's position, but driver's their own position in terms of good evaluation. It has something to do with comfort of drivers. The first condition for drivers comfort starts with guarantee of field of view without any disturbing. Even though the vehicles with advanced technology and comfort could be useless if field of view is not ensured. In this paper, it will focus on improvement of driver's field of view by decreasing A-pillar obstruction angle through optimized design package construction.
내삽노즐 고체로켓의 공기 유동모사시험을 통한 내부유동 가시화

고체로켓모터 추진제 그레인의 핀-슬롯 표면에서의 연소로 인해 생성된 고온, 고압의 연소가스는 그레인 핀-슬롯 및 내삽노즐을 통해 외부로 방출되면서 형성되는 유동은 매우 복잡하고 다양한 형태를 가진다. 핀-슬롯형 그레인 및 내삽노즐을 가지는 고체로켓모터의 2D, 3D 스케일모델에 대한 공기유동 모사시험을 수행하였으며, 회전력 발생 등과 같은 내부유동발생 메커니즘을 규명할 수 있는 효과적인 연기-유동장 가시화 기법의 적용방법에 대한 검토가 이루어 졌다. 실험모델의 투영부를 통해 다양한 광원 및 촬영장치 방향을 이용하여, 축류 실험모델 노즐 선단부에서의 비대칭 와류튜브에 의한 선회류를 가시화하였다. The behavior of combustion-induced internal flow of SRM equipped with fin-slot grain and submerged nozzle is very complex and diverse. Cold air-flow test for 2D and 3D scale models of SRM has been done in order to specify the visualization method to analyze particular internal flow patterns such as roll-torque inducing flow. Swirl flow induced by asymmetric vortical tube also has been visualized through employing various light source and recording directions.
금속분말 연소기의 slag 제거기법 개념 설계 및 Water Film 형성 조건 기초실험

금속분말을 연료로 하는 연소기 개발에 있어 발생하는 문제점 중에 하나는 알루미나 slag 처리이다. 연소기 내부에 Water film을 형성시킴으로써 금속분말 연소기의 문제점을 해결할 수 있을 것으로 기대한다. 이를 위한 선행연구로 water film의 형성 조건에 대한 실험을 수행하였다. 실험 모델에 대하여 물 분사 속도가 증가할수록 원형 모델에 대한 water fim 각도가 작아져, 약 10 m/s이상에서 완전한 water film이 형성되는 것을 알 수 있었다. One of the issues that occurs in development of a combustor using Metal Powder as a fuel is an alumina slag processing. A water film formed inside the combustor is expected to be able to solve this issue. The experiments about the formation of a water film were carried out as a preliminary study. As the tangential velocity of water jet is increasing, the angle derivation from horizontal is decreasing for the test model. Results of the experiments showed that the thin water film on the inner surface appeared at the velocity of 10~15 m/s.
