Shinbundang-line is new Metropolitan Railway which was invested by private capital and is under construction for opening in 2010. Now Shinbundang-line pursues various innovation, for example, an express train which uses long distance of each station, and an unmanned operation. And it may be independent of existing metropolitan railway system from a viewpoint of line and fare system. So according to the present plan, Shinbundang-line will be not able to get sufficient demand because of weak connection with existing lines and monotonous function of the line. And it may be difficult to deliver various innovation which Shinbundang-line prepares to passengers. Hereupon, in this paper, I propose 3 methods for increasing competitive power of Shinbundang-line railway. First, making Shinbundang-line a trunk railway line of southern metropolitan area was proposed in relation to northern and southern extension of it. In addition connection with bus and light rail was discussed. Second, multipurpose usage of Shinbundang-line was proposed as express train and conventional passenger train in that line in addition to simple metropolitan railway. Finally, an effective operation method which Shinbundang-line must have was proposed from unmanned driving and fare system side. These methods can improve Shinbundang-line and then it will solve traffic congestion of southern metropolitan area effectively.

Commonly, a live-line alarm can be used to measure the electric field strength of a high-voltage system to calculate its current, but it is hard to detect the electric field of shielded cables or concealed structures, such as underground distribution cables. Current sensors can detect the magnetic field in a single core wire, but they cannot determine the magnetic field about a double-core wire because the currents flow in opposite directions. Therefore, it is very difficult to detect certain current problems, such as a fault current in an extension line comprised of a double line. In this paper, to ultimately develop a sensor that can detect the current regardless of line conditions, we used a simulation to determine the concentration of the magnetic field dependent on the distribution of the external magnetic field and the path of each line's core.

To ease traffic congestion Seoul Metropolitan Government formulated the 2nd Phase of Seoul Subway Construction Scheme in 1989. The scheme calls for the construction of %60 km of subway which includes addition of 4 more subway lines and extension of 3 existing subway lines in addition to the existing 118 km of subway. As a final stage of the scheme subway line 6 is under planning and design. The line 6 is 36.1 km-long route connecting Ungam-Samgakchi-Changsin-Sinnae. Except for the depot main line wilts be underground and major construction methods are cut and cover and tunnelling. As a tunnelling method New Austrian Tunnelling Method will be adapted. The line will be opened by the end of 1997. With the completion of the line Seoul will have 278 km of subway network and the transport share by subway will be increased from 25% in 1992 to 50% in 1997.

An Asiatic lily (Lilium spp.) cultivar 'Onnuri' for cut and pot flower was developed in 2006 at Jeollabukdo Agricultural Research & Extension Services, Iksan, Korea. The cross was made in 1999 between 'Avignon', orange colored, and 'Nove Cento', yellow colored. A line was preliminarily selected as 'A99-6-48' by reason of stable flower color and shape among germinated seedlings. It had been multiplicated through in vitro culture and then bulbed on field during 2002~2003. After characteristics were investigated from 2004 to 2005, finally it was named as an 'Onnuri' in 2006. Flower of 'Onnuri' belongs to orange-red group with its center shown orange group. Plant height is 92.8 cm, flower size is medium as 13.8 cm. Stigma color is red-brown and blooming direction is upward-facing. Flowering time is mid-June.

This study was conducted to cultivate new Lepista nuda varieties with shorter cultivation period and better fruiting body compared to that of wild strains, for mass production and commercial application. Eighteen genetic resources of L. nuda were collected and grown in boxes using rice straw-fermented growth medium. Four lines with fruiting bodies were formed and selected as cross-breeding lines. Although 657 combinations were crossed through monospore crossing, only 17 combinations were bred between the 'CBMLN-19' line and the 'CBMLN-30' line. Among them, 8 lines with fast mycelial growth and high density were selected. After inoculating the rice straw-fermented growth medium with 14 genetic resources and 8 cross-breeding lines, their incubation period was investigated. Six of the cross-breeding lines completed their incubation in 20 days, while 7 of the 14 genetic resources took more than 40 days to complete their incubation, reducing the incubation period by more than 20 days in most cross-breeding lines. After the incubations were completed, the clay loam soil was covered with for post-cultivation, and when the mycelial cultivation was complete, the formation of fruiting bodies was induced after scraping the mycelial bodies under these environmental conditions: 14℃, 95% relative humidity or higher, and 1,500 to 2,000 ppm CO2 concentration. The temperature was reduced to 6℃ at night, resulting in a low temperature shock. Thus, 4 lines of fruiting bodies occurred from two genetic resources 'CBMLN-31' and 'CBMLN-44' and two cross-bred lines 'CBMLN-96' and 'CBMLN-103'. After inoculation, the longest period for fruiting bodies to occur was 100 days for the control:, the genetic resource 'CBMLN-31', and the shortest period (45 days) was observed for the cross-breeding line 'CBMLN-103'. The result of the investigation of the fruiting body characteristics shows that the cross-bred line 'CBMLN-103' showed a small form with 1.9 g of individual weight and 123validstipes per box, which was the highest incidence among the four lines. Another cross-bred line, 'CBMLN-96', had an individual weight of 5.5 g, which is larger than that of 'CBMLN-103'; however, the number of valid stipes per box was 30 less than that of 'CBMLN-103'. Quantity analysis showed that the control, 'CBMLN-31', had the highest quantity of 783 g per box, followed by the cross-bred line, 'CBMLN-96' with 165 g per box, and then the 'CBMLN-103' with 232 g. The quantity of the two crossbred lines was lower than that of the control 'CBMLN-31'; however, the amount of fruiting bodies was higher, and the cultivation period was shortened by 32 to 33 days. Therefore, these two lines would be selected as superior lines.

Stem and petiole rot symptoms of Valeriana fauriei occurred sporadically in the herb exhibition field in Gyeongsangnam-do Agricultural Research and Extension Services, Hamyang-gun, Gyeongnam Province in Korea. The typical symptom is water-soaking on the stem, rotting, wilting, blighting and the infected plants eventually died. White mycelial mats spreaded over lesions, and then sclerotia were formed on the infected plant parts and near soil surface line. On the basis of mycological characteristics and pathogenicity to host plants, this fungus was identified as Sclerotium rolfsii. This is the first report of stem rot on Valeriana fauriei caused by Sclerotium rolfsii in Korea.

Animation character market in Korea has been dominated by licensed characters (e.g., Walt Disney′s) of which market share is 80%. While market share for Korean characters such as "Mashimaro" and "Little Dinosaur Dooly" is increasing, the application of such characters to fashion products is still limited. For the development of the Korean character market, application of original animation characters should be applied to various fashion products. The main purpose of this study was to design toddler apparel line using "Little Dinosaur Dooly," one of the most popular domestic animation characters. The design focus is the green color of Dooly because the color is the distinctive concept of the brand. Results of the study indicated that developing toddler apparel line with a Korean animation character was a meaningful attempt, as imported licensed characters were dominant in domestic fashion market. The key differentiating factor was the use of green color. In addition, use of various supporting characters, namely Dooly′s friends, demonstrated potential line extension forming animation character groups similar to Warner Brothers′"Looney Tunes."
