Among the various disasters caused by climate change, flooding has account for more than 70% for domestic disaster. This study develops an integrated system that be able to express and spread the disaster information, which can corresponds to the flooding. DRiMSS developed in this study consists of four modules, including RASS, LeVAS, FROK, and FRIENDs. DRiMSS is applied to Sungseo industrial complex in Daegu, and it is confirmed that DRiMSS can produce, express, and spread various disaster information according to the progress of the flooding.

This paper presents the experimental results for reinforcement effect for FRP strengthened steel structures. Bond behavior, flexural, and compression were conducted. First, from bond test, it was able to examine the interfacial behavior and to evaluate the interfacial bond stress between AFRP plate and steel plates. Second, for flexural test, maximum load was increased with increasing FRP layer. Also, debonding failure was observed between steel plates and FRP plates. Third, for compression, for short columns it was observed that two sides would typically buckle outward and the other sides would buckle inward. Also, for long columns, overall buckling observed. The maximum load was increased up to 33% for slender section short columns. From the test, it was able to verify the reinforcement effect for FRP strengthened steel structures.

By amending of the special law on the safety management of the facility, pumping station has been incorporated into kinds of facilities. In this paper, a case study for condition assessment of pumping station is conducted according to the detailed guidelines established for pumping stations. Evaluation index between new and existing guideline is compared.

The results of considerations on the current state of PSC Box girder safety maintenance with external tendons, it appears the extra suggestion of safety maintenance and popularization of technique is needed.

석유화학, 발전 플랜트와 같이 대단위 면적에 대해서 효율적인 비용으로 고위험 시설물 및 설비에 대한 지속적인 모니터링을 위해 서는 무선통신기술에 대한 요구가 증가되고 있다. 그러나 현재의 지그비(Zigbee), 블루투스(Bluetooth) 와 같은 USN기술은 신뢰성 및 보안성 이 취약하여 대규모 플랜트 환경에 적용이 불가하다. 따라서 플랜트 현장에 무선기술을 도입하기 위해서는 ISA(International Society of Automation)과 같은 공신력 있는 표준화 기구에서 제안한 새로운 무선 표준기술의 적용이 필요하다. 본 연구에서는 무선 트랜스미터 기반의 석 유화학 플랜트 안전관리 시스템을 개발하였다. 이를 위해 ISA100.11a 통신모듈 및 LTE 통신모듈을 탑재한 방폭형 무선 트랜스미터를 개발하 였다. 그리고 개발 된 무선트랜스미터를 기반으로 IoT기술을 적용한 석유화학 플랜트 안전관리 시스템을 구축하였다.개발된 시스템은 다양한 방법의 테스트 및 테스트베드 구축을 통해 현장적용성을 검증하였다.

Pumping Station is amended ('15.1.6) a special law (hereinafter siteukbeop) on the safety management of the facility has been incorporated into kinds of facilities. This study aims to introduce siteukbeop drainage pumping stations as part of condition assessment techniques detailed guidelines established for drainage pumping stations being incorporated into the new facility as amended.

The three natural zeolites collected in Yungil-gun, Kyungsangbuk-do, Korea, were analyzed by means of chemical wet methods and X-ray diffraction. The results indicated that the primary species of those zeolites were clinoptilolite mixed with heulandite, feldspar, montmorillonite, and quartz. These zeolites were chemically treated with NaOH, Ca(OH)_2, and HCl solution and their differences were also studied with X-ray diffraction method. The capabilities of removing Cs^+ and Sr^2+ ions with chemically untreated zeolites, chemically treated zeolites, and also with synthetic zeolites were compared. The effect of other cations in removing Sr^2+ ions was also studied. The experimental results showed that Cs+ and Sr^2+ ions could be removed up to 98% and 95% respectively out of 5 ppm with chemically untrearted natural zeolites. The treatment of 0.02N-Ca(OH)_2 and that of 2N-NaOH were most effective in removing Cs^+ and Sr^2+ ions, respectively. It was found that the mountaintop of Sangjung 1-dong natural zeolite treated with 2N-NaOH was most efficient in removing Sr^2+ ions mixed with other cations, compared with any other chemically treated and untreated natural zeolites in this work.
