This study aims to develop a mechanic embroidery bag design that reflects the symbolic image of Korean independence activists who sacrificed for the country so that today's Korea can exist. As a research method, the theoretical consideration and image collection of independence activists were conducted through a literature review and visits to the memorial halls of six independence activists. The bag design was developed using mechanic embroidery textile of 12 motifs manufactured in previous studies through the computer mechanic embroidery sewing machine, and the types were limited to totes, Boston, clutches, baskets, shoppers, hover bags, and hat boxes. The results of this study are as follows. First, it was found that the dense light and shade and delicate color expression of each motif design were the most important and achieved through the proper selection and utilization of embroidery yarn according to the mechanic embroidery expression technique for developing in-depth textile materials. Second, unlike in the past, when machine embroidery was difficult to handle, the spread of embroidery CAD and computer machine embroidery sewing machines made it easier for individuals to develop embroidery products. Third, this study once again emphasized the symbolism of Korean independence activists who sacrificed for the nation to exist at a time when it needs to be recognized due to the lack of fashion and diversity in cultural products containing historical and cultural meaning and values of the country. This study was able to develop computer machine embroidery textiles and various bag designs using various mechanic embroidery expression techniques that can highlight the symbolic image of each motif.

As patients prefer large scale hospitals recently, the interior design of general hospitals are conspicuously improving. In the past, most patients visit hospitals to get treatment on diseases; however, recently patients visiting hospitals for the early prevention of disease is rapidly increasing. Accordingly, contemporary hospitals should meet the wish of patients who want to get medical service in more clean and comfortable environment. The existing studies on hospital interior design were mostly limited on analyzing the functionality of each space; however, studies on the interior design of common use space, which is open to all hospital users, are required now. Accordingly, this study classified the common use space in contemporary general hospitals into lobby space, corridor space, waiting space and resting space. The interior design characteristics of each space were classified into; connectivity with external environment, level change by void, introduction of natural elements, dynamics of space and variety of color. Then a case analysis was done by selecting 12 common use spaces in overseas general hospitals. According to the analysis result, the interior design characteristics were more conspicuous in the sequence of corridor space, lobby space, resting space and waiting space. The interior design elements such as overall space arrangement and material-finishing were relatively acceptable; however, the aspect of a user's environmental behavior, in other words, the psychological aspect, which can lead a patient to natural healing, was relatively insufficient. It is believed that an in-depth interior design focusing on practical users would enable various spatial behaviors. It is hoped that this study would be a help to the interior design of domestic general hospitals as a guideline.

A fish, collected from the Tongbok stream, secondary tributary of the Somjin River system, appeared to be a hybrid between Cobitis longicorpus and Misgurunus anguilicaudatus. The morphological features of this specimen have suborbital spine and distinctive black small spots at the back of its opecleula characterized by C. longicorpus. However, it has totally different body color patterns on the sides of body from the C. longicorpus and The structure of lami-na circularis was less distinctive than that of C. longicorpus. Body measurements of the specimen were similar to the C. longicorpus with the exceptions as caudal peduncle depth(CPD), caudal peduncle length(CPL), predorsal length and CPD/CPL. CPD/CPL were sightly higher and longer than that of the C. longicorpus, and predorsal length was more similar to the M. anguilicaudatus than the C. longicorpus. CPD/CPL value was intermediate between the two parental species. This results indicate that the specimen used in this study is a hybrid between Cobitis longicorpus and Misgurunus anguilicaudatus.

The effects of carburizing pressure and gas ratio on vacuum carburizing properties (uniformity and surface characteristics) have been studied through the analyses of carbon concentration, hardness, surface color, surface roughness and type of carbon bonding. AISI 4115 steel specimens were carburized with various pressures (1, 5, and 10 Torr) at different locations (P₁, P₂, P₃, P₄, P₅, and P₆) inside a furnace held at 950 ℃. Since the carburizing pressure represents the density of the carburizing gas, it plays an important role in improving the carburizing uniformity according to locations in the furnace. As the carburizing pressure increased, the carburizing uniformity according to the sample location was improved, but the surface of the carburized specimen was discolored due to the residual acetylene gas, which does not contribute to the carburizing reaction. Therefore, the carburizing uniformity and surface discoloration have been improved by injecting acetylene gas (carburizing gas) and nitrogen gas (non-reactive gas) in a specific ratio.

This study was performed to validate the procedure of transarterial embolization of the renal artery (TAE-RA) and sclerotherapy of renal pelvis using iohexol-ethanol solution in dogs with unilateral experimental hydronephrosis. Experimental hydronephrosis was induced by unilateral ureter ligation for 20 days in five Beagle dogs. Renal artery embolization with iohexol-ethanol solution was performed using selective catheterization technique in the hydronephrotic kidney and sclerotherapy was done by injection of the iohexol-ethanol solution through percutaneously placed pig-tail catheter. EKG, $SpO_2$ body temperature, pulse, and respiratory rate were within normal ranges during procedures. Average pure ethanol dose for renal artery embolization was $1.1\pm0.3ml/kg$. Renal artery embolization was confirmed by the detection of no blood flow signal at the interlobar and arcuate artery using color Doppler ultrasonography. There were no dogs expired after TAE-RA and sclerotherapy and no side effects associated with regurgitation of iohexol-ethanol solution. The value of BUN, creatinine, ALT, AST, Ca, P in five dogs were within normal range during the experiment period. Ultrasonographically, the mean longitudinal and transverse length and the depth of the embolized kidney significantly decreased at 28 days after TAE-RA. We may conclude that TAE-RA and sclerotherapy with iohexol-ethanol solution is an effective methods for the treatment of unilateral hydronephrosis in dogs.

Some appearances of the result images from the researches on NPR(Non Photorealistic Rendering) look like contrary to the attributes of the real painting. As they are based on only the technical approach rather than the aesthetic and accurate analysis of the real painting which they modeled. Therefore the purpose of this paper is the abstraction of the exact features from the related real painting, the redefine of them applicable to the process, and the embodiment of the painterly NPR algorithms. This paper modeled the Impressionism which were originated in the France at the late nineteenth century. Accordingly, at first, I analyzed the general features of oil paintings and Impressionism paintings, and according to this analyses, I adjusted them to engineering elements(the direction, length, width, texture and speed of stroke, the edge and region of object, depth information and color etc) and programmed. I emphasize the importance and potentiality of the collaboration of artist and technician in the NPR research through the results in this paper.

This study was carried out to investigate the effects of pyroligneous acid on turfgrass growth and to propose usage for sustainable management on Korean golf course green. Each plot was treated with 0, 300, 500, and 800 acid to water solution. On all the plots, turfgrass growth increment and visual quality were measured at fried times. The data were subjected to paired samples t-test and corelation analysis. The summarized results are as follows; 1) Leaf growth increment, density, and root spread depth of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Particularly, 1: 500 diluted solution was superior to the others. 2) Color, texture, and uniformity of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Especially, 1: 500 diluted solution tended to be superior to the others. 3) There were no symptoms of disease in all plots treated with the diluted pyroligneous acid. 1 500 and 1: 800 diluted pyroligneous acid were not thought to trigger or promote disease. 4) Before and after investigating the effect of pyroligneous acid on turfgrass growth ,the soils were analyzed. In all treatments, the chemical properties of the soils did not change noticeably. The chemical properties of the soils might be not changed by the diluted pyroligneous acid treatments. 5) Considering the results mentioned above, 1: 500 diluted pyroligneous acid was the most effective. Though pyroligneous acid is an organic fertilizer and contains only a little nitrogen and phosphorus, 1: 500 diluted pyroligneous acid promoted turfgrass growth effectively. Thus this use might lead to a reduction in the amount of fertilizers used and result in ecologically responsive management of Korean golf courses.

In this paper we suggest a method of detecting the two eyes position of moving viewer by using images obtained through a color CCD camera, and also a method of rendering view-dependent 3D image which consists of depth estimation, image-based 3D object modeling and stereoscopic display process. Through the experiment of applying the suggested methods, we could find the accurate two-eyes position with the success rate of 97.5% within the processing time of 0.39 second using personal computer, and display the view-dependent 3D image using Fl6 flight model. And through the similarity measurement of stereo image rendered at z-buffer by Open Inventor and captured by stereo camera using robot, we could find that view-dependent 3D picture obtained by our proposed method is optimal to viewer.
