  • Ever since the CM was implanted in a domestic construction in 1996, it has been needed to take root and activate the CM system as soon as possible. Especially, the applied CM to private construction sector could be a fundamental barometer that how much changed and being advanced the construction system is This means, it is easy to apply CM to a governmental construction, yet it is hard to expect to successfully fix and activate CM for a private construction project unless they admit the necessity and validity of CM. Dongbu Corporation already acknowledged the need of CM in a private enterprise and willingly applied it to a construction sector while building Dongbu financial center, even before the CM was implanted to this country Therefore, this study suggests that the developmental direction of practical CM by examining effects and problems of the CM process.

  • This study was aimed at analyzing the location and topology of the 'Gungmyo(宮廟)' and in Hanyang Doseong(漢陽都城) during 18th and 19th century. Based on the changes of royal processions(行幸) which had been done between the Gungmyo and the Palace, the Gungmyo can be a barometer of cognition where the city center was. Hanyang Doseong was the the capital of Joseon(朝鮮) which had established by king Taejo(太祖). The city had been organized with Gyeongbok-gung(景福宮) as the center. However, after the Imjin War(1592), Gyeongbok-gung was destroyed and urban space was reorganized with Changduk-gung(昌德宮) which reconstructed first. As most kings in late Joseon dynasty had mainly stayed in Changduk-gung, lots of Gungmyos where a memorial service for king's relatives had been held were established in and around the palace and the frequency of visiting the Gungmyo varied by political purpose. Therefore, the location of the Gungmyo and the rounte of parade were important to impress on the center of urban space. In 18th century, lots of King's procession had been done with Changduk-gung as departure point. The king used to start from Donwha-mun(敦化門), and the routes included main street around Changduk-gung. It shows that the urban center focused on the east of the city. On the other hand, when the king lived in Kyeonghee-gung(慶熙宮), a secondary palace in late Joseon dynasty, the parade started from Hungwha-mun(興化門) and the urban center was expended to the west. Since Gyeongbok-gung had reconstructed in 1865, recognition scheme of urban space had changed from Changduk-gung to Gyeongbok-gung as the center. When the Gungmyo relocated western side of Gyeongbok-gung, spatial proximity of the palace and relation with facilities around downtown fed into changing the route of king's parade.

  • As recent traffic policy focuses on reduction of congestion and environmental contamination, with a catch phrase, 'Green Traffic', Low Carbon Green Growth' and 'Sustainable Development', introducing the new eco-friendly transport means including railway has been emerging as critical issue. Included in the new transport means are BRT, Bimodal Tram and LRT, and this study was intended to evaluate and analyze Bimodal, among others, which generates less emission, noise and vibration thanks to hybrid type traction system employed by Bimodal Tram, which is considered a future-oriented system because of eco-friendly features and cost efficiency as well as punctuality and convenient accessibility to bus. Thus in this study, appropriateness of Bimodal Tram comparing to other system(BRT) was suggested, using conversion traffic from the road, traffic speed and CO2 emission at the metropolitan area and large provincial areas as the barometer in evaluation, and furthermore, the measures applicable to introduction strategy that will meet various functional aspects in urban area in the coming days were developed.

  • Atmospheric infrasound is defined as low frequency inaudible sound waves generated from natural phenomena and human activities. One property of long-distance travelling of infrasound makes it possible to detect the wave propagated from remote sound sources and to understand many geophysical phenomena generating it. Recently, advanced global infrasound sensor arrays are being deployed to monitor the clandestine nuclear test and to study geophysical phenomena in the world. In Korea, five seismo-acoustic arrays consisting of co-located seismometer and micro-barometer have been operated to discriminate the artificial explosions from the natural earthquakes in and around the Korean Peninsula. In addition to the discrimination purpose, these ways also record distinct infrasonic signals from natural phenomena on global scale such as large earthquake, bolide event, volcanic explosion, typhoon, and so on. As a new frontier in monitoring the earth, infrasound is being applied to understand various phenomena in and above the earth's surface.

  • The purpose of this research is to accomplish the goal of science education based in the seventh science course of study by suggesting the plan for development of executable method in the learning process of Earth Science education and establishing a practical model to evaluate its achievement. Furthermore, the idea of this research is to recognize a way of using and consideration at practical use of the model. Since the purpose of the educational evaluation is to maximize the efficiency of school studying, there are some negative aspects in our current method of evaluation to achieve the purpose. New system has been introduced into the educational evaluation to resolve such a critical issue. Despite some positive aspects in the system, it could not be escaped from the multiple choice and pens examination. This could be caused by in various limitations, especially the insufficiency of teachers' awareness and the data about the Performance assessment. This research is to develop and use the practical model for the Performance assessment in consideration of current educational circumstances of Junior and High school. The model of the Performance assessment in this research is to sufficiently evaluate student's ability and skill in the learning process of Earth Science education. Hence, it is dedicated to the education for human being and improve quality in the learning process of the Earth Science education among the modern society, which is characterized globalization and information. Furthermore, it may promote the growth of various character of students and increase creativity and skill for the problem solving.

  • In GPS/INS/barometer navigation system for UAV, vertical channel damping loop was introduced to suppress divergence of the vertical axis error of INS, which could be reduced to the level of accuracy of pressure altitude measured by a pitot-static tube. Because static pressure measured by the pitot-static tube depends on the speed and attitude of the vehicle, static pressure error models, based on aerodynamic data from wind tunnel test, CFD analysis, and flight test, were applied to reduce the error of pressure altitude. Through flight tests and sensitivity analyses, the error model using the ratio of differential pressure and static pressure turned out to be superior to the model using only differential pressure, especially in case of high altitude flight. Both models were proposed to compensate the effect of vehicle speed change and used differential and static pressure which could be obtained directly from the output of pressure transducer.

  • This study analyzed the contents of articles on GMO in Chosun Ilbo and Hankyoreh from 1994 through 2015 to check the trend of reporting on GMO as a science and technology risk issue. As a result, 'risk' and 'anxiety/concern' were continuously treated as important subjects, and there was a lack of depth and journalist's professionalism in all three periods: 'Introduction of GMO technology (1994-2000)', 'Development of GMO technology (2001-2010)' and 'Social acceptance of GMO (2011-2015).' In a comparison between the media with different ideological goals, the Chosun Ilbo had a stronger new-technological inclination to GMO than the Hankyoreh in reporting topics and tones of arguments. As a result of checking the relation of the tones in reporting with the 'risk-benefit' of GMO, reports in negative tones underlined 'risk' while those in positive tones, 'benefit.' This study could suggest improvements of subject bias and unprofessionalism in the domestic science journalism, the barometer of public awareness of disputes over science and technology risk.

  • Yacht have an high powered main engine relatively light hull, so the noise generated from the engine have a bad influence upon the crew and passenger. Recently, cruise yacht is made an attempt by domestic production skill, however the insulation skill of the noise made by the main engine is not satisfy the real purchasing power of the buyer. Like this, yacht cabin's noise level is becoming the barometer to decide the purchase. the method to insufficient. However, if we use the skill of the monitoring equipment and the genetic algorithm system, the circumference of the main engine can be enclosed by an high quality absorbtion wall and the noise levels of the cabins are improved. In this study, the sound absorbtion barrier is experimentally researched by change the volume and the length of the neck for the Helmholtz resonator as the resonator can absorb the noise effectively.
