권석현(Suk-Hyun Kwon),임광수(Kwang-Soo Lim),김민지(Min-Ji Kim) 한국철도학회 2011 한국철도학회 학술발표대회논문집 Vol.2011 No.5

Following public expectations from the emergence of an international agreement with greater legal force after the expiration of the 2012 Kyoto Protocol, Korea is also making efforts to effectively and systematically initiate the mitigation policy and enforce the terms of the international climate change agreement. The majority of domestic industries are candidates for greenhouse gas emission regulation, thereby requiring the proposal of a method that effectively reduces environmental contaminate substances released from railway facilities, following the prediction of an increase in railway usage as an environment-friendly transportation method in the future. Accordingly, this study has quantitatively calculated the amount of released environmental contaminates through the life cycle assessment (LCA) on railway facility constructions, and has evaluated the environmental load and the amount of greenhouse gas emissions through the resulting values. The results of the LCA analysis showed that the amount of environmental load was the highest at the early stages of material implementation and construction, and that the value of global warming was viewed as the highest among the effects. As officially announced by the World Meteorological Organization and the United Nations Environment Program that CO₂ is the main culprit of global warming, the analytical values confirmed that the amount of CO₂ emissions accounted for more than half of the released greenhouse gases at 2.90E+04tons. The environmental load and CO₂ emission rates analyzed in this study are judged to be used in the deduction of the optimum environment-friendly method and quantitative environmental effect of railway facility constructions in the future, as the values can be evaluated based on their degree of environment friendliness.

김병수,권석현,Kim, Byung-Soo,Kwon, Suk-Hyun 한국건설관리학회 2009 한국건설관리학회 논문집 Vol.2 No.3

건설공사에 소요되는 공사비의 개략적인 산정은 건설프로젝트의 계획단계뿐만 아니라 기본설계단계에서 예산을 확정하기 위해서 필수적이다. 현재 국내의 개략공사비 산정모델은 단위길이당 단가 또는 단위면적당의 단가를 이용하여 계산하는 선형적인 단순 모델로써 오차율이 너무 큰 문제점이 있다. 본 연구에서는 과다한 오차율의 문제를 해결하기 위하여 RC라멘교의 특성을 고려하였으며 공사비의 변동특성에 따라 그룹핑(Grouping) 및 대표물량방식 그리고 합성단가를 사용한 모델을 개발하였다. 본 연구의 결과 실제 설계공사비와의 오차를 상당히 줄일 수 있었으며 따라서 발주처나 용역업체에서 RC라멘교의 예산을 산정하는데 기여할 것으로 기대한다. The conceptual cost estimation used the construction project needs for confirm budget not only at the planning phase but also at the preliminary design phase of the construction project. Present, the conceptual cost estimation model have problems the rate of error is very large because the linear simple model calculate by use the cost of the unit meter or the unit square. This study development the model used grouping and the key quantity method, the mixed unit cost for solve problem of the very large rate of error. The result of this study reduced difference of between the real design construction cost therefor it expect that contribute to the client or the service company estimate budget of RC rahmen bridge.

Objective : The current study investigated the prevalence and clinical characteristics of sexual exhibitionism and frotteurism, which was conducted for the first time in Korea. Methods : Among 568 total subjects (mean age $19.28{\pm}5.0$ year), 109 were victims of sexual exhibitionism (19.2%, VSE) of which 57 were females (91.9 percent) ; and 57 were victims of sexual frotteurism (10.9%, VSF) of which 57 were females (91.9%). The participants completed the self-reported scale for epidemiological and clinical characteristics. Results : Incident frequencies of above two times of VSE and VSF were 49 (50.0%) and 20 (32.3%), respectively. Incident locations of VSE were school/office 37 (33.3%), street 28 (25.6%), and near home 20 (18.3%). Also, incident locations of VSE were inside of bus 12 (19.3%), subway 12 (19.3%), subway/bus station 8 (12.9%), near home 8 (12.9%), and school/office 7 (11.3%). Notifying rate of VSE and VSF to the police were 7.3% and 0%, respectively. Also, notifying rate of VSE and VSF to family or friends were 72.5% and 58.1%, respectively Conclusion : These results suggested that VSE and VSF had a common prevalence, which could be different from behavioral and emotional characteristics of a control group ; and the victims were shown to require an active intervention by supportive social system.

One-third of total energy and 50% of $CO_2$ emissions arise from construction phase. Because of this global amount of energy consumption and $CO_2$ emission, we must do our best to solve this problem. But our existing ways of meeting this problem has focused on the energy consumption saving of the construction and dwelling stage. On the other hand, we has been treated too lightly for handling the $CO_2$ emissions problem during the maintenance management and the demolition process so far,. In this paper, we quantitatively predicted and evaluated the environmental load in each construction step during all life cycle. And, we developed the environmental load assessment program for each construction step. And we proposed the reliable decision support model for objective and reliable environmental load assessment and reduction. This result must help the development of construction technology and low carbon & green growth. 세계적인 에너지 및 온난화 문제로 이에 대한 개선은 필연적인 과제가 되었다. 그러나 기존의 대응은 건설단계와 운용단계의 에너지 소비절감에 집중되어 왔다. 상대적으로 유지관리 및 해체 폐기단계의 관리는 소홀하였다. 본 연구에서는 건설 전 생애주기에 걸쳐 각 건설단계 별로 발생하는 환경부하를 정량적으로 예측하여 평가하고, 각 공정별로 환경부하를 평가할 수 있는 시스템을 개발하였다. 또한 건설 전과정에서의 환경부하 평가 및 저감을 위한 객관적이고 신뢰성 있는 의사결정 모델을 제시하였다. 또한 프로그램의 현장 적용성을 검토하기 위해 실제 해체공사를 대상으로 시험평가를 실시하였다. 이를 통해 친환경 건설기술 개발에 일조하고 저탄소 녹색성장에 기여하고자 한다.

리스크 평가절차 도입을 통한 VE 대안 평가방법 개선

박진호,김정훈,현창택,김현주,권석현,Park, Jin-Ho,Jin, Zheng-xun,Hyun, Chang-taek,Kim, Hyun-joo,Kwon, Suk-hyun 한국건설관리학회 2018 건설관리 : 한국건설관리학회 학회지 Vol.19 No.5

발주자, 건설사업관리자, 설계자, 시공자, VE 전문가 등 참여자 역량에 의해 성패가 좌우되는 VE 프로젝트에서는 체계적인 절차를 따르는 것이 중요하다. 하지만, 실제 VE 업무에서는 개략평가만을 실시하거나, 개략평가와 상세평가를 통합하여 수행하는 경우가 있다. 이러한 경우, 중요한 대안일지라도 리스크에 대하여 평가하는 것이 어렵다. 이에 따라, 선행단계에서 제안된 대안이 후행단계에서 다시 기존안으로 돌아가는 회귀제안(returning alternatives)이 발생하여, 해당 대안에 대한 반복작업으로 인해 VE 업무효율이 저하되는 경우가 종종 발생한다.이에 본 연구에서는 VE 대안을 구체적으로 분석하고 체계적으로 평가하여 회귀제안 발생을 최소화하기 위해, VE 대안의 리스크 평가절차(risk assessment process for VE alternatives)를 제안하였다. 이는 VE 대안을 구체적이고 체계적으로 평가하여 회귀제안을 최소화하기 위한 평가절차로서 의의가 있으며, 회귀제안에 대한 반복업무를 줄임으로써 VE 업무의 효율을 높일 수 있을 것으로 예상된다. Since the success or failure of VE projects depends on the capabilities of participants, including owners, construction managers, architects, general contractors and VE experts, it is important to follow systematic procedures. However, it is often the case that only a rough evaluation is performed, or the rough and detailed evaluations are integrated in actual VE tasks. In this case, it is difficult to analyze and evaluate the alternatives in terms of risk, even for the important alternatives. This in turn leads to the so-called returning alternatives where the alternatives proposed in the preceding stage are returned to the original plans in the following stage, and thus the repetitive work for the alternatives often decreases the efficiency of the VE task. In this regard, this study proposed a risk assessment process for VE alternatives in order to minimize the occurrence of returning alternatives based on the systematic analysis and evaluation of VE alternatives. It will increase the efficiency of VE tasks by reduces the number of regression alternatives.
