There are many eyes that recognize Korean traditional performing arts as low, unorganized, and not a play. However, there is clear in the Korean traditional performing arts have a story with a perfect narrative structure. From the Miyal which accepts the Western tragedy theory to the Gangneung Gwanno Mast drama which contains the love story of the comedy, many Korean traditional performances contain the elements of narrative even though the contents are very simple. It is true that there are very few things with perfect narrative structure among the Korean traditional performance that has been passed down so far. It is the responsibility of the researchers to unearth and restore these, and it is the task of the creative artists to create new ones according to contemporary philosophy. If these two fields communicate smoothly, we will be able to look at the future of our traditional performing arts more brightly than now. As a result, it will also be a challenge to solve the problem of letting Korean traditional plays penetrate ing the world market.

The stagnant growth in 3D market due to 3D movie contents shortage is encouraging development of techniques for production cost reduction. Elimination of vertical disparity generated during image acquisition requires heaviest time and effort in the whole stereoscopic film-making process. This matter is directly related to competitiveness in the market and is being dealt with as a very important task. The removal of vertical disparity, i.e. image rectification has been treated for a long time in the photogrammetry field. While computer vision methods are focused on fast processing and automation, photogrammetry methods on accuracy and precision. However, photogrammetric approaches have not been tried for the 3D film-making. In this paper, proposed is a photogrammetry-based rectification algorithm that enable to eliminate the vertical disparity precisely by reconstruction of geometric relationship at the time of shooting. Evaluation of proposed algorithm was carried out by comparing the performance with two existing computer vision algorithms. The epipolar constraint satisfaction, epipolar line accuracy and vertical disparity of result images were tested. As a result, the proposed algorithm showed excellent performance than the other algorithms in term of accuracy and precision, and also revealed robustness about position error of tie-points.

This article studies on the identity of Korean Culture and the direction of Korean culture contents. Our Korean society goes on to value-pluralism and cultural diversity. In this point, we need to confirm the identity of our Korean culture. And we meet with the crisis of Humanities. Humanities is the core of our culture. It is the key point to make identity of our Korean culture as cultural universality and to apply it to develop Korean culture contents for the revival of Humanities. The core contents of Korean culture lies in the ancient myth, the thought of Hwarang, Confucianism, Neo-Confucianism, Buddhism, Taoism, the practical thought, thought of Yangmyeong study and the thought of East study and so on. On the basis of these thoughts, the core of Korean culture are humanity, harmony, the spirit of Punglyu, thought of life- esteem, ethics of environment etc. I suggest that we can apply our cultural core ideas those I analyzed above to develop Korean culture contents in the fields of cinema, music, cartoon, animation, game, character, digitalization, cultivation of experience programs of Korean culture etc. In addition, I suggest their commercial application like e-learning and culture contents education.

This study investigated the actual state and transformation of the major garden ornaments in Changdeokgung Palace(昌德宮) in the modern and contemporary period, focusing on Nakseonjae(樂善齋), Juhamnu(宙合樓), Jondeokjeong(尊德亭), and Daebodanji (大報壇址). This study can be used as useful data for establishing the restoration and maintenance plan of the garden ornaments in Changdeokgung Palace, and the main results of the study can be summarized as follows. First, according to a photo taken by the Czech Vráz, in 1901, a total of six garden ornaments, including a stone pond and odd-shaped stones, were located in the backyard of Nakseonjae. Since liberation, arbitrary relocation of garden ornaments has frequently occurred, and in the process, two odd-shaped stones, originally located on the first floor of the terraced flower bed, have been transferred to the backyard of Gyeonghungak(景薰閣). Second, unlike the late Joseon Dynasty when 「Donggwoldo(東闕圖)」 was produced, odd-shaped stones were arranged symmetrically in the backyard of Juhamnu in the early 1900s. It was a traditional style garden ornament with similar appearance, size, and design. However, all the odd-shaped stones in the backyard of Juhaumnu were relocated to other places in the 1970s and 1980s. One is located at the rear of Aeryeonjeong(愛蓮亭) through the entrance of Bingcheon(氷泉) and the vicinity of Geumcheongyo(錦川橋), and the other remains in front of the Yeongyeongdang Jangnakmun(演慶堂 長樂門). Third, among the garden ornaments located in the area of Jondeokjeong in the past, one odd-shaped stone is now relocated around the stone bridge near the pavilion and the Yeonghwadang(暎花堂) with its components separated. The bondstone near Yeonghwadang was relocated in 1990 for the purpose of installing an imitation of Angbuilgu(仰釜日晷). Another odd-shaped stone has been relocated to the front door of the Secret Garden(後苑), and now it is difficult to grasp the location. Fourth, the two bondstones remaining in the Daebodanji were actually building materials that were used as the foundation stone for the entrance pillars of the Yi Royal Office Building(李王職廳舍) during the Japanese colonial period. After liberation, the Yi Royal Office Building was reorganized into Imperial Estate Administration Office(皇室財産事務總局), and when the office building was burned down in 1960, the stone statues and foundation stones placed on the stylobate were relocated to the Daebodanji. The bondstone at Daebodanji is a representative example of construction materiasl being mistaken for gaeden ornaments.

Every spring, Korea is always plagued by sandy dust from the western region of China and Mongolia. Yellow sand is causing an environmental problem to Japan and far into the American continent, let alone Korea. At present, the western region of China is going under desertification at a great speed due to climatic change and humans' damaging activities. To cope with this, each country including China is considering ecological restoration of deserts through planting. Accordingly, this research conducted a vegetation survey on Baicheng district which is a representative dry land of western China to obtain a basic data for ecological restoration of a desert. The survey revealed that Setaria viridis which invaded an arid land made a succession into Setaria viridis-Cannabis sativa var. fruderalis community together with Artemisia mongolica-Setaria viridis community due to the increase in salt concentration and alkalization subsequent to dryness. It was also found out that there finally formed Artemisia mongolica community on a flat intense in harsh wind and dryness with the continuous worsening of environmental conditions. There appeared a different type of vegetation on hilly districts where sporadic shade could come into being because the air humidity could be available relatively there. Frequently, typically appearing at the whole survey area, the Tributlus terrestris community was found to make succession into Tribulus terrestris-Cleisrogenes squarrosa community due to the aggravation of soil environment. In addition, with the worsening of the environment at hilly districts, there formed Clesirogenes squarrosa community resistant to dryness, salinity in soil and strong alkalinity. Further, there appeared higher plant life totalling to 62 taxa comprising 58 species and 4 varieties with 27 families and 49 genuses at the whole survey area. Among these, Compositae plants excellent in resistance to environment was surveyed the most, accounting for 27%.

Purpose : We sought to determine the early change of ventricular geometry and function after concomitant surgeries of modified Dor procedure and mitral valve annuloplasty by using magnetic resonance imaging. Materials and Methods : We enrolled 21 patients with dilated heart failure who underwent modified Dor procedure (n=8), mitral valve annuloplasty (n=6), or both surgeries (n=7). Cine MRI was used to assess left ventricular dimensions and function before and after surgery. We measured the left ventricular end-diastolic and end-systolic volumes and the dimensions of the left ventricular long-axis and short-axis. Left ventricular stroke volume, ejection fraction, and sphericity index were calculated from these measurements. These parameters were analyzed and compared between three different surgery groups to explain the combined effect of the concomitant surgeries. Results : MRI was performed within average $12\;{\pm}\;15$ days (range 1-58 days) before and $38\;{\pm}\;50$ days (range 7- 231 days) after the surgery. The patients who underwent concomitant surgeries had more profound enlargement of left ventricle and decreased contractility prior to surgery than those in the patients who underwent single surgical procedure. Left ventricular end-diastolic volume and endsystolic volume significantly decreased in all patients regardless of surgery type after surgery. Ejection fraction significantly increased only in the patients who got modified Dor procedure without mitral valve annuloplasty (25.4% to 40.7%). Sphericity index increased in patients with modified Dor procedure but decreased in patients with mitral valve annuloplasty (0.65 to 0.78 vs. 0.75 to 0.65). In the patients who underwent concomitant surgeries showed no significant change in sphericity index after surgery. Conclusion : The early change of the left ventricular geometry and function after the concomitant surgeries with modified Dor procedure and mitral valve annuloplasty in patients with dilated heart failure includes a marked reduction in left ventricular volume and in stroke volume. The shape of the left ventricle does not change because the effect of sphericity index decrease from mitral valve annuloplasty is counteracted by the effect of sphericity index increase from modified Dor procedure. Improvement of left ventricular ejection fraction is not the early change after the concomitant surgeries.
