The organic and holistic recognition method about nature in east asian philosophy is also applied to the study of the human body in Korean medicine. In Korean medicine, the human body is being understood from a holistic point of view rather than a mechanical or reductive one. The main east asian philosophies are the heavens thought and the Yin-yang/Five Phase Theory. This study will explore the influence the general flow of heavens thought has on explaining the human body in Korean medicine and the formation of how the human body is perceived in "Huangdineijing"(黃帝內經). First, the primitive meaning of heaven was developed to include the natural heaven of Xia (夏), the lord heaven of Shang(商) and the moral heaven of Zhou(周) dynasties. Among these, the natural heaven notion of the Xia(夏) dynasty which recognized heaven as the one with the power to create everything. This was followed by Taoism which established the contrasting system of heaven and earth. Based on this, "Huangdineijing"(黃帝 內經) developed the perception of the human body, taking into account, heaven as the original substance to generate the human body through the mutual sympathy between heavenly energy and earthly form. The perspective of the correspondence between nature and human in "Huainantzu"(淮南子) and "L$\breve{u}$shichunqiu"(呂氏春秋) was succeeded by Tung Chung-Shu(董仲舒). Based on this development, the perception of the human body in "Huangdineijing"(黃帝內經) is related to the seasonal cycle and the notion of night and day to balance the physiology of the human body. It recognizes that its structure, shape, emotional state and physiological actions are correlated with heaven.

As a recurrent congestion of urban freeway occurs in almost same time and section, it is possible to manage the congestion effectively by the expectation and advance correspondence. In the existing traffic management system. we have used pattern data to manage a recurrent congestion. But it is not applicable to an urban freeway which kas various traffic circumstance. In this study, the probability by travel speed using a statistical distribution method will be used to predict the probability of recurrent congestion. It is expected that we can get the point of time and the duration of recurrent congestion, and we can devise an effective advance correspondence and a transportation operation.

In order to optimize the design of unidirectional fiber reinforced composite C-rings, a viscoelastic load relaxation behavior was analyzed under a point load. Initially, the deflection and bending stiffness were calculated based on the elastic beam theory and the viscoelastic relaxation and creep behaviors were derived from the elastic solution using the correspondence theorem. Besides the orthotropic mechanical properties of the composite, asymmetric mechanical property due to the different tensile and compressive properties were also considered. Except the deviation affected by the relatively large thickness of the specimen compared to the radius, the calculated relaxation showed good agreement with the experimental result.

A new finite element formulation based on the relaxation type hereditary integral is presented for a time-domain analysis of isotropic, linear viscoelastic problems. The semi-discrete variational approximation and elastic-viscoelastic correspondence principle are used in the theoretical development of the proposed method. In a time-stepping procedure of final, linear algebraic system equations, only a small additional computation for past history is required since the equivalent stiffness matrix is constant. The viscoelasticity matrices are derived and the stress computation algorithm is given in matrix form. The effect of time increment and Gauss point numbers on the numerical accuracy is examined. Two dimensional numerical examples of plane strain and plane stress are solved and compared with the analytical solutions to demonstrate the versatility and accuracy of the present method.

This paper discovers and introduces the collection of letters, "A Collector of Correspondence from Chinese Intellectuals (中朝學士書翰錄)" which was made by Kim Youngjak(1802~1868) who had collected the letters from Chinese intellectuals. "A Collector of Correspondence from Chinese Intellectuals (中朝學士書翰錄)" is a collector which contains handwritten letters to Kim Youngjak from Chinese people such as cheng gong shou(程恭壽), weng xue han(翁學涵), zhang bing yan(張丙炎), shao yan han(少言翰), and li wen yuan(李文源). Kim Youngjak had frequent meetings with Chinese intellectuals not only directly but also indirectly. He had exchanged letters with li bo heng(李伯衡), shuai fang wei(帥方蔚) for 30 years. In 1858, he went to Beijing and met Chinese intellectuals ye ming li(葉名澧), zhang bing yan(張丙炎), wu kun tian(吳昆田), cheng gong shou(程恭壽), and zhao guang(趙光). After coming back to Chos?n, he continued to exchange letters with them. "A Collector of Correspondence from Chinese Intellectuals (中朝學士書翰錄)" contains autograph letters by Kim Youngjak and Chinese intellectuals. It has ten letters for Kim Youngjak written by cheng gong shou(程恭壽), weng xue han(翁學涵), zhang bing yan(張丙炎), shao yan han(少言翰) and so on. One letter and five poems which zhao ting huang(趙廷璜) wrote to the son of Kim are also contained. The letters by zhao ting huang(趙廷璜) shows a sincere friendship with Kim Youngjak. The relationship between li bo heng(李伯衡) (who had exchanged letters with Kim for 30 years) and his son li wen yuan(李文源) proves that the cultural interchange between Korea and China had lasted successively. Kim Youngjak has not been widely known in academic circles yet but should not be ignored for the study in the cultural interchange between Korea and China. He proposed to have a relationship with li bo heng(李伯衡) and shuai fang wei(帥方蔚) first and they sent back positively. Therefore, they had a literal and private relationship by only exchanging letters each other. Also considering the fact that Kim Youngjak, as a man of high birth, had a close relationship with Chinese intelletuals, we can notice that Chinese and Korean intellectuals had open minds based on sincerity and trust. This was possible because many intellectuals before him like Hong Daeyong made a basis of the tradition of companionship. At this point, the relationship between Kim Youngjak and Chinese intellectuals and "A Collector of Correspondence from Chinese Intellectuals (中朝學士書翰錄)" have an important value. The collections of Kim Youngjak's works contain only several letters and poems which he sent to Chinese intellectuals. Accordingly, the letters in "A Collector of Correspondence from Chinese Intellectuals (中朝學士書翰錄)" are important to understand the aspects of their interchange.

Forest roads of 16,424km have been constructed as infrastructure for efficient management of forest. The demand of forest road have been also increased steadily with SOC conception for forest management and wood production. But, accuracy verification by completion drawing of forest road needed aspects extration of geographic information to sound like forest road construction and completion drawing. However, verification for completion drawing has not ascertained. This study carried out the evaluation for position accuracy about constructed forest road in Chungcheongnam-do for evaluating horizontal position accuracy of completion drawing of forest road. In result, first of distance of completion drawing and real route designed completion drawing longer than the real route as Gongju 83m, Seosan 66m, Nonsan 27m and Dangjin 19m, respectively. Second, RMSE by point-correspondence was 11m~14.7m, buffering analysis appeared difference of 18~24m. Finally, index of shape was the similar completion and real route through 6.5~7.4 and data information of forest road corresponds to be perfect. For such reasons, the existing completion drawings have a problem that it cannot use graphic information for drawing digital map according to the regulation, and there is an urgent need for improvement to solve this problem in the process of design and construction.

We propose a method for 3-dimensionally reconstructing an object using a line that includes the midpoint information from a single image. A pre-defined polygon is used as the primitive and the recovery is processed from a single image. The 3D reconstruction is processed by mapping the correspondence point of the primitive model onto the photo. In the recent work, the reconstructions of camera parameters or error minimizing methods through iterations were used for model-based 3D reconstruction. However, we proposed a method for the 3D reconstruction of primitive that consists of the segments and the center points of the segments for the reconstruction process. This method enables the reconstruction of the primitive model to be processed using only the focal length of various camera parameters during the segment reconstruction process.

여러 대의 카메라를 통해 캡춰된 2차원 데이터를 사용하여 3차원의 좌표를 추출하기 위해서는 각 카메라의 2차원 영상 데이터들의 대응점(correpondence point)을 구해야 한다. 이를 위해 에피폴라 제약조건(epipolar constraints)을 이용하여 에피포라 라인(epipolar line)에 근접한 점을 추출할 수 있다. 에피폴라 제약조건을 사용하면, 실제 원하는 점 이외에 많은 수의 고스트(ghost)가 발생할 수 있다. 또한 카메라로부터 은닉(occlusion)된 점들로 인해 모든 카메라에서 대응되는 점이 존재하는지의 여부를 보장할 수 없다. 본 논문에서는 가 카메라의 대응관계를 k-partite graph로 모델링하고, 전역 탐색을 위해 가중치를 적용하여 클릭(clique)을 추출함으로서, 고스트가 제거된 대응점을 구한다.

This paper describes a new method to determine the 3D-shape of objects consisting of specular planar surfaces. This method exploits a light source which is made of a diffuse plane with a grid pattern encoded in an M-sequence and uses a single image of the light source reflected by the objects to acquiring orientations and positions of the surfaces of the objects. When grid lines of the light source are reflected by a specular planar surface and perspectively projected on an image plane, a set of lines vanishing at a point are obtained on the image plane. The orientation of the specular planar surface is determined by using the vanishing point, and the position is determined by using the correspondence between lines on the image and lines on the light source, which is obtained by employing a characteristic regularity of the M-sequence. Before the vanishing points are calculated, the lines on the image are classified and correlated with the surfaces of objects by using slopes and positions of the lines and the regularity of the M-sequence. This method requires only a single image.

This paper focuses on recovering systematic biases during LIDAR calibration, particularly using natural surfaces as control features. Many previous approaches have utilized all the points overlapping with the control features and often experienced with an inaccurate value converged with a poor rate due to wrong correspondence in pairing a point and the corresponding control features. To overcome these shortcomings, we establish a preventive scheme to select the pairs of high confidence, where the confidence value is based on the error budget associated with the point measurement and the linearity and roughness of the control feature. This approach was then applied to calibraring the LIDAR data simulated with the given systematic biases. The parameters were successfully recovered using the proposed approach with the accuracy and convergence rate superior to those using the previous approaches.
