최근 이상기후의 영향으로 특정지역 중심의 국지성 집중호우 발생 빈도가 증가하고 있으며, 집중강우의 영향으로 하천의 범람 사고 또한 증가하고 있는 추세이다. 이와 관련하여, 본 연구에서는 수문시설의 안전성 확보를 위해, 기후변화 측면에서 현재 운영 중인 안전점검 및 정밀안전진단 세부지침의 개선 사항을 검토하고, 이에 대한 개선방안을 제시하고자 한다. 먼저 본 연구에서는 수문시설의 안전성평가 실시 현황, 현장적용 사례 및 평가기준 비교 검토를 통해 개선사항을 도출하고자 하였으며, 검토된 결과는 다음과 같다. 시설물의 안전성 평가는 선택적으로 수행할 수 있도록 규정하고 있어, 주기적 평가가 수반되지 않고 있으며, 최근 수위 변동에 대한 시설의 안전성 확보여부가 확인되고 있지 않은 실정이다. 또한 수문시설의 조작대 접근성 및 문비 구조검토 안전성 평가는 설계 당시의 홍수위를 기반으로 한 평가항목으로, 하천의 홍수위 상승에 취약적 요소가 내재되어 있으며, 수문시설의 기존 평가체계에서는 시설물의 기능적 특성에 따른 평가결과를 확인하기 어렵다는 한계점이 있다. 이에 본 연구에서는 기존의 조작대 접근성, 내하력 및 문비 구조검토 안전성 평가 항목 외에 추가적으로 홍수조절능력에 대한 안전성평가 항목의 신설의 필요성과 기준을 마련하고, 수문시설의 기능적 특성을 고려한 단계별 평가 체계를 구축하였다.

With the introduction of COBie (Construction Operation Building Exchange) in BIM technology enabling an automatic transfer of design and construction information to operation and management (O&M) phase, the BIM centric O&M management system development process has been tested on the subject of architectural types of building. However, for now, there is a need to investigate the technical feasibility of COBie application to civil structures including industrial facilities. This study takes both "O&M Guideline for Public Wastewater Treatment Plant" and a real wastewater treatment plant into account for the purpose, in which the latter is intended to supplement the result of the first. The findings are three-folds: (1) COBie, as an asset modeling, is not sufficient enough to encompass commissioning data, (2) more relevant IFC development and family library build-up useful to modeling wastewater treatment plant is imperative, and (3) well-planned coordination and organization of COBie data-set in line with O&M practice will enhance the feasibility of the COBie in industrial facilities. The result could be used for a basis study for COBie application, particularly in industrial facilities.

Park-and- Rides are intermodal transfer facilities providing a staging location for travellers to transfer between transportation modes. They are an alternative to alleviate transportation problems such as traffic congestion and air pollution in metropolitan areas. Siting Park-and-Ride facilities belongs to a kind of multi-criteria spatial decision making problems being associated with a combination of various location factors. The purpose of this paper is to provide a method and procedure to evaluate the location suitability of Park-and-Ride facilities using GIS(Geographic Information Systems). Using GIS-based suitability analysis, land value, landuse, road accessibility, public transportation accessibility, possibility to intercept automobile trips, distance to activity center and competition with existing facilities were evaluated as location factors. The suitabilities of individual factors were combined to produce a composite map with a specific weight scheme. Then a given number of sites with high suitability score were selected as potential facility locations and their demand were evaluated based on a commutershed with parabolic shape. The suggested method and procedure will provide useful information in determining Park-and-Ride sites and designing their structure.

The objective of this study was to evaluate the efficiency of a modified filtration system treating non-point source (NPS) pollutants. The developed Best Management Practice (BMP) technology was designed based on the geographical and climatic characteristics of the site. A lab-scale test experiment was conducted using three different hydraulic loading rates representing the first flush flow, average flow and overflow conditions during a rainfall event. Water quality analysis was performed on the water samples taken at the inflow, outflow and infiltration during the test experiment of the lab-scale BMP. Also, the water and mass balance at different hydraulic loading rates was determined. Results from the lab-scale test experiment showed that the lab-scale BMP had a high removal efficiency of 80-90% for all NPS pollutants. The overflow test condition obtained the lowest removal efficiency among the hydraulic loading rates because it gave less opportunity for the pollutants to be filtered and retained inside system. The infiltration ratio was approximately 1 % of the inflow and outflow. Increasing the infiltration ratio requires technical approach of soil amendment where the BMP is installed.

Major countries stay to expand invest in R&D to promote new growth engines in the future and to secure new technologies and Korea is also expanding to R&D investment. Quality of R&D investment is getting more Important than quantity of R&D investment because Korea's indicator related to R&D investment is already world class with other countries's investment scale by comparison with GDP. According to this trend, Korea's policy in R&D is focusing the R&D Innovation Plan and "Utilization of R&D Facility and Equipment(F&E)" has been getting important. In this research, it research on facility and equipment management plan through Defense R&D Equipment information System(DRES). It analyzes existing process F&E in Defense field and Nation. Furthermore, it explains major process, function, and menu reflecting Defense F&E management rule enacted recently. Lastly, it shows the development direction for Defense F&E management.

As the future national defense plan of government focus on advanced weapon system, military maintenance facility becomes more important. However, military maintenance facility has been managed by director's experience and simple mathematical calculation until now. Thus, the optimization for the management of military maintenance facility is suggested by more scientistic and logical methods in this study. The study follows the procedure below. First, simulation is designed according to the analysis of military maintenance facility. Second, independent variable and dependent variable are defined for optimization. Independent Variable includes the number of maintenance machine, transportation machine, worker in the details of military maintenance facility operation, and dependent variable involves total maintenance time affected by independent variable. Third, warmup analysis is performed to get warmup period, based on the simulation model. Fourth, the optimal combination is computed with evolution strategy, meta-heuristic, to enhance military maintenance management. By the optimal combination, the management of military maintenance facility can gain the biggest effect against the limited cost. In the future, the multipurpose study, to analyze the military maintenance facility covering various weapon system equipments, will be performed.

For the fire-fighting industry to advance, it is necessary to conduct research on which parts of the fire-fighting law should be changed from the system level, and to study the opinions of the fire-fighters whoa re working in the fire-fighting industry today, and to identify what needs to be changed. Moreover, it is necessary to become aware on the preventive measures to take to avoid fire so that the citizens can lead stable life. Design business among the fire-fighting facility business, it is the fire-fighting facility business that serves as the most basic when constructing building structure. This is an important legal matter that follows the fire-fighting business, fire-fighting audit business and even the maintenance and management business. This research sought to help the fire-fighting industry to contribute to the life of the general public and to increase welfare by identifying the problems pertaining to the fire-fighting facility design business among the fire-fighting industry so that the industry can become the fire-fighting industry that the citizens are interested in. Moreover, direction for advancement is proposed. As for the improvement measures for the fire-fighting policy pertaining to the fire-fighting facility design business, it is divided into the machinery and electricity fields in terms of the legal system pertaining to the general fire-fighting facility design business. Likewise, specialty in design is deficient. Thus, it should be integrated in a systematic level to contribute to the safety of the general public.
