Recent navigation systems provide quick guide services, based on processing real-time traffic information and past traffic information by applying predictable pattern for traffic information. However, the current pattern for traffic information predicts traffic information by processing past information that it presents an inaccuracy problem in particular circumstances(accidents and weather). So, this study presented a more precise predictive traffic information system than historical traffic data first by analyzing route search data which the drivers ask in real time for the quickest way then by grasping traffic congestion levels of the route in which future drivers are supposed to locate. First results of this study, the congested route from Yang Jae to Mapo, the analysis result shows that the accuracy of the weighted value of speed of existing commonly congested road registered an error rate of 3km/h to 18km/h, however, after applying the real predictive traffic information of this study the error rate registered only 1km/h to 5km/h. Second, in terms of quality of route as compared to the existing route which allowed for an earlier arrival to the destination up to a maximum of 9 minutes and an average of up to 3 minutes that the reliability of predictable results has been secured. Third, new method allows for the prediction of congested levels and deduces results of route searches that avoid possibly congested routes and to reflect accurate real-time data in comparison with existing route searches. Therefore, this study enabled not only the predictable gathering of information regarding traffic density through route searches, but it also made real-time quick route searches based on this mechanism that convinced that this new method will contribute to diffusing future traffic flow.

The following results could be obtained from the research on awareness and satisfaction of the tourists who joined the program 'A Journey in Search of King Mu's Road'. With regard to awareness of the site tour program, tourists replied that they participated in the program mainly because of their interest in education for their children. They expressed great needs for the municipal government office to maintain walkways, signboards and guide maps as well as to reinforce safety facilities as a measure to increase satisfaction with the site tour on the part of visitors and tourists. In terms of satisfaction with operation and management of the site tour program, the contents of the program were highly appreciated while it turned out necessary to rediscover garden culture resources and to develop and operate an expanded internal tour course for tourists to look around inside the relics by utilizing the recently excavated Baekje historical resources. As a consequence, it might be expected possible to experience and educate the local history and garden culture thanks to the historical culture and environmental values that have been preserved in the Baekje cultural circles. Moreover, the importance of walking trips will be recognized for its effects to allow those who get tired from daily life to come into contact with nature, practice self-reflection and care for their health as well.

According to the rules, a crash cushion is supposed to set up products that is satisfied with the standard of a performance test after performing the car crash test by road safety facilities and management guide. For development of crash cushion, performance should be estimated through the car crash test eventually. However, there is no reasonable design method which considers passenger's safety and only depend on crash test without an alternative plan. Therefore it incurs a loss materially and takes a lot. Therefore, we are asked to create a systematic design of the crash cushion. This study shows that a scientific basis of applying single degree of freedom when it designs the crash cushion after analyzing vehicle crash test data of crash cushion and also represents design of crash cushion through single degree of freedom response spectrum using calculated by crash test data on crash cushion.

In this study, the original scenery of Baegun-dong Garden in Gangjin was compared with that of the reconstructed site to suggest directions for restoration in the future. The diachronic prototype scenery of the Baegun-dong Garden was derived by integrating the elements of the original and contemporary prototype sceneries from the old poetry series. The old poetry series is comprised of "Baegun-dong 8Yeong(詠)" by Lee Damro(李聃老), "Baegun-dong 10Su(首)" by Song Ikhwi(宋翼輝), "Baegun-dong 12Gyeong (景)" by Jeong Yakyong(丁若鏞), and "Baegun-dong 14Gyeong" by Lee Siheon (李時憲). Guidance for directions for future restoration was suggested through a comparative analysis between the diachronic prototype scenery of Baegun-dong Garden and the current scenery of the restored site. The research result is as follows. First, the prototype scenery of Baegun-dong Garden was a harmonic view composed of the camellia forest road, 'Baegun-dong' the letter carved on a rock, a cliff 'Changhabyeok(蒼霞壁)' the red letter written by Jeong Yakyong, paulownia trees, waterfalls and a maple forest. Outside the Byeolseo(別墅), there were a red plum blossom forest, a pine forest, and a bamboo forest, as well as the view of Okpanbong(玉版峯) from Jeongseondae(停仙臺). In the yard, there were Chwimiseonbang(翠微禪房), Jug-gak(竹閣), Pyeongsang(榻), a lotus Bangji(方池), Gogsugeo(曲水渠) and Hwagye(花階). Cranes were even raised in the yard. Second, comparing the diachronic prototype scenery of Baegun-dong Garden with its restored site, following a restoration guide is suggested. There should be more water flow in Baegun-dong Valley and Jug-gak should be restored. 'Changhabyeok' the red letter should be carved on the stone wall. Trees should be controlled for a better view of Okpanbong from Jeongseondae. More trees and plants, such as red plum blossom, pine tree, paulownia trees, azaleas(映山紅), chrysanthemum, orchid, daffodil, and lotus should be planted in the yard. A system of integrated guide boards is also required for effective information transmission for visitors.

Fresh water that can be used by a person of the total amount of water on the planet is increased because it is less than 0.01 % except underground water, ice and snow, etc. water management response need. In order to protect and efficiently utilize water resources, major countries are conducting water footprint studies that can quantitatively estimate the amount of water put into the operating phase of the resource harvesting phase, mainly agriculture. Korea has also recently developed a number of policies in order to cope with water shortages, and in the construction industry, as well as the need for basic research to support it has been emphasized. This study was constructed DB up to the raw material harvesting step, the transport step, the production stage in order to estimate the water consumption of resources to be put into the work process to target the drainage of the road. Water usage estimation method was utilized the method presented in the Water Footprint Manual and the environmental score card certification guide, unit water usage each drainage main method was calculated after estimating the water footprint considering the water character factor, indirect water and the direct water, the water consumption factor of material input to each process. Brown asphalt, rebar, remicon of the drainage material as a result of the water footprint calculation accounted for 97 % of the total. Drainage method is a culvert, a side channel, a culvert wing wall, reinforced concrete open channel accounted for 92.2 % of the total. Drainage total step-by-step calculated water consumption and water footprint was found in order of raw material harvesting step, transport stage, production stage. Water footprint each drainage method or total drainage material calculated in this study can be used as a base data in the agricultural and construction sectors. In order to increase the reliability of the analysis, it is believed that further overseas databases will be needed for continuous review and research.
