Although understanding and interesting of safety and maintenance on domestic facilities are important, there is little recent on a comprehensive and integrated survey of actual condition. Therefore this study asserts the necessity of the survey methodology. The purpose of this study is to investigate current situation and to suggest integrated facility breakdown structure, and to establish survey process of actual condition on domestic infrastructure facilities and buildings.

This paper developed analysis model with measured data and geometric nonlinearity for more precise evaluation of structure behavior of suspension bridge. This analysis model helps to make plan and evaluate of structure behavior for accidents such as traffic, typhoon and earthquake. Also, this helps to make maintenance and management plan for structure.

To manage the data measured from Honam high-speed railroad(HSR) infrastructure(environmental noise reduction structures, track structures, catenary system), we are trying to establish an integrated database through analysis of the developed infrastructure technologies and standards, construction of prototypes on the fields and evaluation of infrastructure performance according to the increment of train speed. In this paper, integrated monitoring center for management of measured data is suggested.

Recently, Advanced automated infrastructure measurements have been made in the Honam high speed railway test-bed. In the future, Real time measurements will be the common based on these technologies. Here, we looked at the domestic and international trends and utilizing the inspection method of Railway Structures using self-powered sensors and wireless network technologies.

The purposes of this study is to identify a proper spot to create a symbolic place for the International Jazz Festival and to improve the connections among the place assets of Gapyeong as a place marketing strategies. To this end, the analysis and interpretation of spatial structure was conducted using space syntax. The results of the study showed that the entire structure of the space formed in the axis of a total of 200. The value of total integration was 0.833, which is relatively low, and the local integration degree was 1.588 degrees. Gahwa Street has the highest value of full integration (1.264) among the major points related with the Festival, followed by the former Gapeyong Station area (1.189). As a result, the former Gapeyong station area was identified as a recommendable place for symbolic place because it is highly accessible to the surrounding areas and spacious enough to function as a plaza. Developing a cultural street occupied by jazz cafes, concerts, shops and restaurants, and transforming the old railroad into a linear park will enhance the image of jazz city and help place marketing.

Test-bed was constructed in Honam High-speed railway due to evaluate the suitable infrastructure for operation of 400km/h level speed. To evaluate performance of roadbed in test-bed, several sensors installed in the standard roadbed, soft ground, transition zone as bridge and earthwork. In contrast to existing long-term monitoring, system developed was designed and builted on site to log-time operation automatically. Therefore, the measured data collected monitoring system and analysis results can be databased continuously from construction to operation of railway for study design criteria about long-term behavior of roadbed.

Needs for a new technologies of infrastructure systems arose, following the development of next generation EMU(Electric Multiple Unit) train with maximum speed over 400km/h. For high-speed operation tests of the new EMU, a high-speed railway infrastructure test-bed was constructed in a 28km long section of the Honam High-speed Railway. Diverse sensors and monitoring system was installed for continuous monitoring of the railway. Due to such effort, further demands and needs of the integrated monitoring system was derived in a more comprehensive and long-term perspective.

This study was conducted to investigate the Structural Health Monitoring(SHM) system built in large-scale structures. Recently large-scale structures such as bridges and high-rise building have installed SHM system and using the SHM system, large-scale structures are monitoring the status of structures. In many practical cases, SHM systems are used sensor, such as strain gauge, inclinometer, accelerometers, seismic, wind anemometer, GPS, to monitor status of structures. This case study foreground potential future research dealing with SHM system using integrated sensor module.

국내에서 수집된 블루베리 34품종의 식별을 위하여 SSR 마커를 이용하여 품종별 SSR 프로파일 데이터베이스를 구축하였다. 블루베리 품종의 식별에 적합한 마커를 선정하기 위하여 6개 품종을 대상으로 총 49개의 마커를 분석하였다. 6개 품종간에 높은 다형성과 재현성을 나타내고, 밴드패턴이 선명한 17개의 마커를 선발하여 공시된 34품종을 분석하였을 때 총 115개의 대립유전자가 분석되었다. 대립유전자의 수의 분포는 2∼15개를 나타내었고, 마커당 평균 대립유전자의 수는 6.8개로 분석되었다. PIC 값은 0.248∼0.888의 범위에 속하였으며 평균값은 0.671로 나타났다. 115개의 대립유전자를 Jaccard 방법에 의해 유사도를 산출하고 비가중 산술방식에 의해 집괴 분석한 결과 공시품종의 유전적 거리는 0.31∼0.81의 범위로 나타났고 계통도는 유사도 지수 0.40을 기준으로 할 때 종에 따라 3개의 그룹으로 구분되었다. 17개 SSR 마커에 의해 34품종이 모두 식별되었고, 34품종을 식별할 수 있는 3개의 최소마커 조합을 선정하였다. 본 결과는 블루베리 품종식별과 신품종 보호 심사를 위한 유전자 분석 자료로 유용하게 활용될 것으로 사료된다.

이 연구에서는 중소지간 합성형 강거더교량에 대한 신뢰성 해석을 위해 강거더와 콘크리트슬래브의 강성을 토대로 처짐을 고려한 한계함수를 구축하여 신뢰성해석을 수행하였다. 확률적 하중과 저항모델을 통해 처짐을 예측하기 위해 계산에 필요한 변수들을 확률변수로 고려하였다. 강재의 부식에 의한 단면의 감소, 그리고 콘크리트의 크리프는 합성형교의 처짐에 많은 영향을 미친다. 따라서 이 연구에서는AASHTO LRFD 기준으로 설계된 교량에 대해 시간에 따른 변수를 고려하여 강재단면의 감소와 크리프의 영향을 통계적 모델에 반영하기 위해 몬테-카를로 시뮬레이션 기법을 이용하였으며, 처짐과 사용성을 고려하여 다양한 지간과 거더간격을 가진 교량에 신뢰성 해석을수행하였다. 그 결과, 장지간 교량의 경우, 단지간 교량과 비교해 보았을 때 상대적으로 크리프와 강재단면감소의 처짐에 대한 영향이 작았으며, 이에 반해 단지간 거더 교량의 경우 크리프의 진행에 따라 처짐에 많은 영향을 미친다는 것을 알 수 있었다.
