The change in environment of construction industry and the advancement of information technology require the improvement of construction project efficiency. However, construction industry still lacks performance-measuring tools that are the requirements of efficient project management system. In case of the schedule management system, schedule is usually being managed by result-oriented measurements such as completion time, spent cost, and progress rate, which are not good enough to control the overall continuity of work-flow. This research aimed to systemize the overall construction process and to develop the indicators for measuring performance of TACT activities during finishing work period that can contribute to the systemization of TACT management. 건설산업의 환경변화와 정보기술의 발달에 따라 건설사업 효율성 향상의 필요성이 커지고 있다. 그러나 건설사업의 효율성 제고를 위한 관리시스템의 필수요건이 되는 성과측정 도구는 여전히 부족한 실정이다. 한편, 공정관리의 경우, 공사수행 결과로 나타나는 시간, 비용, 진도 율 등의 실적위주로 관리되고 있으며, 진행단계에서의 전체 작업간의 연속적 흐름에 대한 관리는 제대로 이루어지지 못하고 있다. 따라서 본 연구에서는 건축공사의 계획단계에서부터 진행단계, 최종 평가에 이르는 프로세스의 시스템화를 시도하였고, 특히 택트 공정관리의 시스템화를 통하여 공사수행 과정 중의 마감공사 수행 정도를 측정할 수 있는 지표를 개발하고 이를 활용하는 방안을 제시하였다.

Purpose: In the case of mass disaster, the establishment of temporary medical facilities for the first aid and treatment is required for the stable accommodation of patients caused by the disaster. However, the criteria for decision making related to the deployment of field emergency medical facilities are not specified. So, The purpose of this study is to draw considerable factors needed for the deployment of field emergency medical facilities and to make proposal for site selection process of field emergency medical facilities on the basis of the factor. Methods: This study performs text mining of disaster-related laws, guidelines and documents to derive key factors affecting site selection, also proposes a decision making process and conducts virtual deployment to validate the process. Results: The key factors for the site selection derived as the size of the damage, the size of the DMAT inputs, the location of available place, and distance to the disaster base hospital. As a result of virtual deployment following proposed decision making process, It is confirmed that the site of field emergency medical facilities is changed depending on the type of disaster, even if the scope of the disaster damage was the same. Implications: The deployment of field emergency medical facilities requires a separate criteria for each type of disaster, not uniform, as a future research a quantitative approach of the criteria needs to be performed.

건축공사에서의 리스크 관리자들은 전체 공기에 영향을 미치는 공정리스크 관리에 대한 중요성에 대해 공감하고 있지만 그 에 대한관리 절차 및 도구 등이 체계화되어 있지 않아 공정관리에 어려움을 겪고 있다. 또한 기존의 리스크 관련 연구에서의 리스크 분류체계는 현장업무 중심으로 이루어지지 않아 실용화되기에 한계가 있다. 따라서 본 연구에서는 전체 공정에 많은 영향을 미치는 철골공사를 대상으로 공사 프로세스 중심의 리스크 분류체계와 주요 공정 리스크 요인과 연계한 업무 플로우를 제시하였고, 공정리스크 관리업무의 효율성을 제고하기 위해 공정리스크 중요도를 분석하였으며, 이를 기반으로 공정 리스크 요인별 대응방안 및 세부대책으로 이루어진 공정 리스크 관리 도구를 개발하였다. The purpose of this study is to develop a supporting tool for efficient management, at preconstruction phase, of the schedule risk that is able to generate at construction phase. The main contents of this study to develop a practical tool are as follows. First steel work was selected as a relevant trade and a risk breakdown structure focused on the process of steel work having large effect on total construction process was made. Secondly, the work flow considering schedule risk factor was made and schedule risks that must be managed preferentially through analyzing the grade of importance for risk was selected. Finally, based on above two procedure, the management form for schedule risk was developed It is necessary to accumulate abundant data for schedule risk for other construction process and to develop a manual and a schedule risk management system.

The amount of delivered parcels have been increasing according to the change and expansion of consumption pattern through e-commerce, and they are required to minimize breakout or failure under the delivery. In this study, we measured and analyzed the distribution environment data (vibration and impact) occurred in the packaging, which were prepared with 5 types by the weight and dimension, distributed from Seoul to Busan in Korea by 2 parcel delivery service companies through e-commerce order. Date showed the parcels had 3-5 times of drop impact and 0.3-0.7 m of drop height on average, and 0.8 Grms of vibration acceleration from equivalent equation to the vertical direction. The significant gap in service quality was not found between 2 parcel delivery service companies. This study is expected to be useful for designing the suitable packaging in order to enhance safe transportation of the delivered packaging, and furthermore useful for developing Korean testing method for Field-to-Lab simulation.

This study was conducted to find out the soil CO2 emission characteristic due to rain fall pattern and intensity changes. Using Automatic Opening and Closing Chambers (AOCCs), we have measured annual soil respiration changes in Pinus koraiensis plantation at Seoul NationalUniversity experimental forest in Mt. Taehwa. In addition, we have monitored heterotrophic respiration at trenching sites (4×6 m). Based on the one year data of soil respiration and heterotrophicrespiration, we observed that 24% of soil respiration was derived from root respiration. During the rainy season (end of July to September), soil respiration at trenching site and trenching with rainfall interception site were measure during portable soil respiration analyzer (GMP343, Vaisala, Helsinki, Finland). Surprisingly, even after days of continuous heavy rain, soil water content did not exceed 20%. Based on this observation, we suggest that the maximum water holdingcapacity is about 20%, and relatively lower soil water contents during the dry season affect the vital degree of trees and soil microbe. As for soil respiration under different rain intensity, it was increased about 14.4% under 10 mm precipitation. But the high-intensity rain condition, such as more than 10 mm precipitation, caused the decrease of soil respiration up to 25.5%. Taken together, this study suggests that the pattern of soil respiration can be regulated by not only soil temperature but also due to the rain fall intensity.

최근 전 세계적으로 다양한 유형의 재난이 발생하고 있으며, 재난으로 인한 피해를 최소화하기 위한 재난관리 체계구축의 중요성이 대두되고 있다. 국내에서도 마우나리조트, 세월호 사건 이후 국민안전처 신설, 국가안전관리기본계획 발표 등 재난안전과 관련하여 많은 정책적 개선을 추진하였으며, 재난거점병원을 확충하는 등 시설 확보에도 많은 노력을 기울였다. 그러나 미국, 유럽, 일본 등 선진국과 비교하여 인구 당 응급의료시설이 부족한 실정이며, 재난 시 다양한 기관의 미흡한 협조체계로 효율적 재난관리가 이행되지 못하고 있는 실정이다. 따라서 본 연구에서는 재난상황에 요구되는 응급의료시설의 효율적 구축과 체계적 운영방안을 제시하고자 하며, 이를 위해 선진국 대비 국내 응급의료시설의 현황을 파악하고, 재난현장 응급의료시설 유형 및 상황별 구축 방안을 제시하고자 한다. Recently, various types of disasters have been occurring all over the world, and the importance of disaster management system to minimize damage caused by disasters is emerging. In Korea, we have made many policy improvements related to disaster safety, such as the establishment of the National Security Service and the announcement of the National Safety Management Plan and made a lot of effort to secure facilities such as disaster relief hospitals after the Mauna Ocean Resort Gymnasium Collapse and the Sewol-ho incident, However, compared to advanced countries such as the US, Europe, and Japan, there is a shortage of emergency medical center per population, and disaster management systems have not been implemented efficiently due to lack of coordination among various agencies. The purpose of this study is to propose the efficient construction and systematic management of emergency medical facilities required for disaster situations. For this purpose, it is necessary to identify the current status of domestic emergency medical facilities compared to developed countries.
