The costumes (including mask) of the first World Master series of The National Changguk Company of Korea, Achim Freyer's 'Mr. Rabbit & Dragon king' is directly designed by Achim Freyer who was in charge of direction and stage design. The new form called Pansori opera is proposed for modernization of Korean traditional opera, it maintained the original form of music yet introduced play form of opera. The costumes and stage also promoted modernistic transformation while maintaining the original Korean form. The overall concept of 'Mr. Rabbit & Dragon king' costumes emphasizes comical effect by abstractness like childlike scribble. It expressed characteristic of characters diversely through exaggeration and expansion while maintaining original form of Hanbok, used surface of costumes as a drawing board, and created flat and geometrically transformed silhouette. The complicated characters was caricatured like everyone is doing mask play by using masks, and it still maintained sophisticated oriental color with modern application of five cardinal colors. It may seems it just mixed our traditional elements like a hint of humor, however, it could be known that it introduced various techniques in it to deliver new subject while maintaining the original form of 'Mr. Rabbit & Dragon king'. From this study, open mind for our tradition and need for diverse attempt could be rediscovered and could also see the possibility to contribute on creating a Nation Brand of traditional performing art.

A software interface called CGI-K including device driver routines and graphics primitives for the grphic board "K" was designed, implemented in the Design Automation Laboratory of KAIST and installed on IBM PC/AT, using assembly and C language supported by TMS 34010 grphics processor. Several algorithms generating the graphics primitives such as box, circle, pie chord are proposed. The drawing speed of CGI-K on the graphic board K was found out to be three to ten times faster than that of the EGA for several examples. A 2-D graphics editor called GRIM (graphics input and modification) and a 3-dimensional graphics renderer called IPCHE which can draw 3-D objects were developed as two major application programs running on CGI-K. The graphics primitives supported in GRIM include polygon, box, circle, and ace. The IPCHE receives a 3-D objects data file and displays the 3-D object on the screen with hidden surface removal, shading, and perspective scaling.

Purpose : The aim of this study was to compare the effects of the abdominal draw-in exercise (ADIE) and the dead bug exercise (DBE) on the pelvic anterior tilt angle and the activities of the gluteus maximus (GM), erector spinae (ES), and semi tendinosus (ST) during prone hip extension. Methods : A total of 22 female adults with weak abdominal muscles were divided into two groups: ADIE group (n=11) and DBE group (n=11). The muscle activities of the GM, ES, and ST along with the pelvic anterior tilt angle during prone hip extension were measured using a wireless surface electromyograph and gyro sensor before performing the prescribed exercise. Two groups conducted the assigned exercise for 10 minutes. After the exercise, their muscle activities and the pelvic anterior tilt angle were equally re measured. Results : In the DBE group, the muscle activity of GM was significantly increased after the intervention (p<0.05). However, there was no significant difference between the two groups in the amount of increase in the activity of GM (p>0.05). Moreover, in both groups, the activity of ES and the pelvic anterior tilt angle decreased significantly after the intervention (p<0.05) The decreased quantity in the pelvic anterior tilt angle and in the activity of ES showed no difference between the two groups (p>0.05). In the activity of ST, there was no significant difference within and between the two groups (p>0.05). Conclusion : Therefore, we suggest that ADIE and DBE are effective for women with weak abdominal muscles since the ES activity and pelvic anterior tilt angle are reduced during prone hip extension.

This paper reviews literature from history, media studies, and anthropology to provide an expansive spatio-temporal framework that examines the epistemic and material aspects of computing technologies in the Anthropocene. Reconceptualizing computing as planetary technology has become imperative in the Anthropocene, in which digital sensors, devices, and infrastructures are increasingly mediating human activities to understand, utilize, and consume the Earth. Drawing upon the previous works that have examined the social, political, and cultural elements of information and communication technology (ICT), we provide three perspectives to reconsider the relationship between computing technology and the planet. Computing technologies are increasingly being adopted to measure the anthropogenic impacts on the plant, while these technologies themselves also take part in leaving deep social and material traces upon the Earth's surface. In this sense, we argue that the Anthropocene and computing technologies are co-constructive. Such a renewed perspective on computing and the Anthropocene, we hope, would bring new scalar imaginations to future studies on ICT.

The statistical analysis for the springtime windstorm in Korea shows that Yeongdong region has the highest occurrence frequency during recent 10 years. The objective of this study is to find possible mechanisms for the downslope windstorm formation in the Yeongdong region by using a mesoscale numerical model, WRF. Dynamical process, wave breaking (hereafter WB), is qualitatively investigated as the candidate mechanism for a windstorm event occurred in 5 April, 2005. WB is developed in upper troposphere downstream, since stable air is lifted by the Taebaek mountain. This process can cause and maintain the severe downslope windstorm by drawing the upper flow down to the surface. And the intensified downslope wind leads the hydraulic jump (hereafter HJ) in downstream region. Froude numbers at Chuncheon (upslope side), Seorak Mountain (crest), Yangyang (lee side), and the East Sea (distant downstream position) are estimated by about 0.4, 1.0, 1.6, and 0.6, respectively. This result implies that the accelerated and supercritical (Fr>1) flow adjusts to the ambient subcritical (Fr<1) conditions in the turbulent HJ. In addition, we find the formation of upstream inversion near top level of the mountain cause the intensification of HJ. Experiments to examine the orographic effect on the mechanisms suggest that the magnitudes of WB and HJ are larger in the experiment of higher topography, but there is no significant difference of windstorm magnitude among the experiments. Another important result from these sensitivity experiments is that the intensity of downslope windstorm strongly depends on the magnitude of upper (2~4 km) wind in upstream side.

Generally, the inspection is hard work and needs a lot of time. So, this work contains subjectivity of inspector owing to carry out the visual evaluations through naked eye. Thus, the result of inspection is not objective and reliable. The purpose of this study is to develop new inspection technique to solve above problems and to provide convenient inspection work. We make a new inspection system using digital image processing technology. This program can stitch each image and detect cracks of surface of concrete bridge. Also, It can extract an investigation drawing from the picture. Also, this program is a kind of management tools designed to have some functions such as converting the image data obtained from cameras to Data-Base format, searching and storing the data. At first, we try to make a automatic extracting program. But, changed by semiautomatic method because of various problems. Through field experiments, the application of this inspection system with specialty software has proven to be much faster, safer, and reliable than the inspections carried out by the naked eyes in managing safety of the bridges. The new inspection method may be able to make the inspection of bridge more efficient and reliable.

The artistic idiom of expression in modern poster art make great use of visual illusion. These visual illusions serve carne in sharp relief the idea or concept the artist wishes set forth to the viewer. However we must look at area beyond the psychological impact of visual illusion to the evolutionary history of past and present poster art. The yes of such investigation reveals that the interest in the sub psychological impact of visual illusion is especially deep and reaches for back into the past in the West. Looking at the a of the 15th century in Europe, there is the tradition of drawing that gives the illusion of distance depth, arid substance know as trompe l'oeil, while actually utilizing a flat surface. On needs only look at the works of Arzhibauld, anamolphoses and the surrealism in the works Eschew to realize their influence modern poster art.
