최두회,방홍순,김옥규 대한건축학회지회연합회 2018 대한건축학회연합논문집 Vol.20 No.4
Plant projects are increasing with the development of construction projects. Between 2011 and 2012, it had the best results, and its overseas expansion is on the rise. As construction companies and plant businesses develop, they face more risk factors. Risk factors have a potential personality and are difficult to predict when and where they will occur. Preliminary studies and past reports show that to reduce risk factors, you must deal with the initial parts of the project. The risk management process for each prior study is based on different methods, and the criteria and items are also different for each plant company. Accordingly, this study analyzed the risk management processes considered during the plant project stage and proposed the risk management process at the plant winning phase by compiling the expert opinions in the risk - related advance study process and past case analysis. Application to the current projects has led to a review to see if actual use is possible.
플랜트 PRM (Project Risk Management) 체크리스트 항목 선정을 위한 연구
최두회,방홍순,이태형,김옥규 한국건설관리학회 2018 한국건설관리학회 논문집 Vol.19 No.1
Currently, as construction businesses develop and diversity, risk became one of the most crucial considerations. Risks are potential and difficult to predict by nature. Also, they are important as they influence delay in construction period and increase of project costs. In construction projects in South Korea and elsewhere, the importance of risk management widely recognized and relevant research is being conducted continuously. The companies use PRM checklist but apply different criteria and items. For efficient risk management in plants, plant PRM checklist is necessary. This study analyzed risk factors that are taken into account in construction projects and proposed a plant PRM checklist based on case analysis and opinions of experts. Also, it rated the frequency and importance of each risk.

유기 자연농법 실천농가기술에 대한 객관적인 평가를 위해 이들 농법 실천농가에 대해 실태조사 및 현지 포장에서 작물재배 시험을 실시한결과, 다음과같다 유기 자연농법 실천농가의 토양화학성은일반토양보다 pH가높았으며 , 인산, 칼숨함량이 많았고, 특히 유기농법실천농가의 유기물함량이 높았으며 , 작물별 소득은 시설고추〉시설오이 〉과수(배) )상추〉벼 순이었다. 유기 자연농법 농가에서 사용되고 있는 농자재 는 22~25종이었고 이들 자재의 화학적 특성은 pH가 낮고 비 료성분함량이 적었으며 자재에 소요되는 경비는 토양 검정 +최소방제보다 3 ~5배 높았다. 유기 , 자연농법 재배에 의한 작물 수량은 토양검정 + 최소방제구보다 낮았으며, 농약대체 활용자재 시용에 의한 병충해 방제효과는 적었다 유기 자연농법구 모두 화학비료를 사용하고 있었으며 시험 후 토양의 화학성은 토양검정구보다 유기 자연농법구에서 가축분퇴비 시용에 의해 유기 물 및 인산,칼리,석회 함량이 높았다. 1n order to evluate me effectiveness of me organic and narural farming rechniques, me acrual conditions of me rechniques were surveyed and some crops were cultivated in siru. The contents of available P,Os, exchangeable Caι and organic matter of me organic and natal farming soil as well as soil pH were higher than mose of me non-organic and non-narural farming soil, and especially me coment of organic matter amouming 54.0 g/kg was dominam. 1ncome of me farmers cultivating me different crops wim me organic and natural farming was high in order of red pepper in vinyl house > cucumber in vinyl house > fruit(pear) > lettuce in vinyl house >rice. The agriculrural materials used in organic narural fàrming were ranged from 22 to 25 ands, representing low pH amoumed from 2.9 to 4.5 and low comems of fertilizer ingrediems. The expense for purchasing me materials was from mree to fìve rimes higher than thar of soil testing plot. The yields of resr crops in the organlc and narural farming plors were lower man mose of soil resring plor, and the efficiencies of me disease and pesr control by me application of me subsrimres for pesticide were lower than mose by pesticides
