This study was carried out to obtain basic information on breeding using PCR-aided RFLP technology which can identify the variation inter- and intra-species of ginseng in the level of DNA. It was intended to investigate banding pattern on psbA and rbeL genes of chloroplast DNA in ginseng after treating with restriction enzymes. To isolate psbA and rbcL genes of chloroplast, both psbA-N, psbA-C primer and rbcL-N, PX-1 primer were used. As a result, 1,008 bp band of psbA gene and 1,336 bp band of rbcL gene were appeared, which was optimal and expected molecular weight. In addition, primers to isolate atpB, rpoB, trnL, and trnF genes were used, resulting in the expected 1366, 900, 1500 and 1008 bp bands. Genes of psbA and rbcL isolated by PCR were cut by restriction enzymes, Sau3A, TaqI, AluI, HaeIII, and RFLP pattern was investigated. KG line and other species of ginseng were cut by TaqI treatment, and bands were located in 800 bp. The treatment treated by AluI also showed the same 800 bp band in KG line and other species. In HaeIII treatment, 500 bp of faint bands were shown in case of KG line, whereas any bands were not observed in other species. All chloroplast genes formed bands by PCR amplification. However, it was not evident to distinguish intra-or inter-species of ginseng after restriction enzyme treatment. Therefore, more restriction enzyme treatment or sequence comparison method should be considered for further experiment.

A very large shell-structure built in shipyards like ship hulls or offshore structures are joined by welding through full process. As the welding contains a high thermal cycle at a local area, the welded structures should be distorted unavoidably. Because a distorted ship block should be revised to the designed value before the next stage, the ability to predict and to control the weld distortion is an accuracy level of the yard itself. Despite the ship block size, several present thermal distortion methodologies can deal those sizes, but it is a different story to deal full ship size model. Even a fully constructed ship hull not remaining any welding can have an accuracy issue like outfitting installation problems. Any present thermal distortion methodology cannot accept this size for its recommended element size and the number. The ordinary welding breadth at erection stage is about 20~40 mm. It can hardly be a good choice to make finite element model of these sizes considering human effort and computational environment. The finite element model for structure analysis of a ship hull is prepared at front-end engineering design stage which is the first process of the project. The element size of the model is as fine as the longitudinal space, and it is not proper to obtain a weld distortion at the erection stage. In this study, a methodology is suggested that a weldment can be shrunk at original place instead of using structural finite element model. We cut the original shell elements at erection weld-line and put truss elements between the edges of cut elements for weld shrinkage. Additional truss elements are used to facsimile transverse weld shrinkage which cannot be from the weld-line truss element shrink. They attach to weld-line truss element like twigs from barks. The capacity of developed elements is verified through an accuracy check of erection process of a container vessel at the apt. hull. It can be a useful tool for verifying a centering accuracy after renew and for block-separating planning considering accuracy.

We should extract lines and data which consist of the table in order to classify the table region and analyze its structure in document image. But it is difficult to extract lines and data exactly because the lines are cut and their lengths are changed, or characters or noises are merged to the table lines. These problems result from the error of image input device or image reduction. In this paper, we propose the better method of extracting lines and data for table region classification and structure analysis than the previous ones including commercial softwares. The prposed method extracts horizontal and vertical lines which consist of the table by the use of one dimensional median filter. This filter not only eliminates the noises which attach to the line and the lines which are orthogonal to the filtering direction, but also connects the cut line of which the gap is shorter than the length of the filter tap in the process of extracting lines to the filtering direction. Furthermore, texts attached to the line are separated in the process of extracting vertical lines. This is an example of ABSTRACT format.

The objectives of this study were 1) to investigate the clothing needs of physically han- dicapped children, 2) to present the basic data to make the slacks patterns which meet the specific needs of physically handicapped children under study. Questionnaires were administered to 38 mothers of handicapped children and the subjects for the wear test were five handicapped children using wheelchair. The fabrics used for slacks wear test were: muslin woven with cotton, stretchable jean woven and double jersey knitted with cotton and polyester fabrics. The results obtained from this study were as follows: 1) The majority of the handicapped children were wearing ready·made-garments and their mothers considered the fabric elasticity first. 2) The slacks wear test indicated that the slacks ease of 8 cm should be added above the natural waist line in the back for the wheelchair bound children. 3) In a sitting posture on the wheelchair, $3\~4$ cm should be cut below the natural waist line in the front but in a standing posture, $1\~2$ cm should be cut below the natural waist line in the front. 4) The double jersey (cotton/polyester) slacks was highly estimated of ease ana length of slacks in a sitting posture. The stretchable jean (cotton/spandex) slacks was estimated high of appearance but muslin slacks (cotton) was less estimated of ease and appearance of slacks.

The purpose of this study is to develop the appropriate brassiere pattern for women. Total of 6 brands with same design and 75A, 80A size brassieres(total 12 brassieres) were compared and analyzed for pattern, cup size and patterns. SPSS 10.1 statistic process was used for data analysis. The outcom of this study is summarized as follows. Total length of brassiere by grade were performed smaller than the standard difference 5cm. For 1/2 front cover length, There were no significant differences between 75 and 80. The reason for lower line of wing is shorter than upper line of wing is because side support is cut side ways considering lower line of wing is sewn more toward front than upper line of wing. Even it is same A cup size most cup related sizes become larger according to underbust comparing with cup capacity, they range from 146.67cc to 172.83cc for same A cups. Among same A cups with difference underbust there was average of 26.16cc differences. For relations of material, sewing technology and expansion rate, all 6 brands had zigzag type sewing for upper line tape. For every 0.3cm height, there were $17{\sim}21$ stitches. When urethane mixture is similar expansion rate is higher while number of 1 inch zigzag are high. For elasticity, zigzag stitch expand side ways for more expansion.

This study focuses on the visual effects of various neckline-haristyle combinations on the perception of face image and type. The study employed a model with oval face and examined 35 combinations made up of five necklines and seven hairstyles. Looking at various face images depending upon different necklines, in case of round, V, boat square, and high necklines, long wave hair and medium wave hair produced a feminine image of marked individuality; long straight hair that covers the forehead and medium straight hair gave an image of charm and purity as well as an image of neatness; and long straight hair short cut hair showed an intellectual image. Regarding the perceptual type of face depending upon the different necklines of round, V, square, and high, the long straight hair covering the forehead and medium wave hair had the effect of an optical illusion that made the face look short and round; and short cut hair made the face line look distinct and the face look oval and slender.

We have analyzed the stability for cut-slopes at main street 3-2 line section in Pa-ju local industrial complex. After studying an additional boring test, laboratory test and face mapping etc., we have determined the extent of reinforcement, slope inclinations and soil strength parameter from the analysis of test results. After changing the inclination of slopes for ground limit and carrying out the analysis of slope stability, we applied the Mass Nailing Method to the site because of need for reinforcement to soil and weathered rock slopes. In slope for soft and hard rock sections, we also reinforced the sections that are difficult to obtain the safety without reinforcement in alteration zone.

An adequate method for the prediction of machining errors is essential to improve productivity and product quality. But it is known that there is a remarkable difference between values calculated by conventional roughness model and measured values of actual machined surfaces under high efficient cutting condition. This paper introduces the theoretical analysis of characteristic lines of cut remainder to evaluate a geometrical surface roughness accurately. In this study, analytic equations of the characteristic lines are derived from the surface generation mechanism of ball end milling considering the actual trochoidal trajectories of cutting edges. The predicted results are compared with the results of conventional roughness model.
