The Battery Energy Storage System(BESS) has lots of advantages such as load levelling, quick response emergency power(spinning reserve), frequency and voltage control, improvement of reliability, and deferred generation and transmission construction. The economic feasibility requires justification from the customer side of meter to promoting the dissemination of BESS nationally. In this paper, we proposed the economic assessment model of customer owned Battery Energy Storage System(BESS) which is complemented and improved the existing model. The proposed model is applied to the typical customer type(light-industrial commercial, and residential) which are taken from the statistical analysis on the load profile survey of Korea Electric Power COmpany (KEPCO). The economic assessment performed for each customer type to justifying their economic feasibility of BESS installation from the economic measures such as payback period, overall benefits, ROI, and ROR. The results of this paper are useful to the customer investment decision making and the national energy policy & strategy.

Climate technology applied to address climate change requires a comprehensive review such as environmental and social acceptability in addition to economic feasibility. Not only mitigation and adaptation technologies, but also integration of climate technologies into a business model with other relevant technologies including ICT, finance, and policy instruments could enhance technical, economic, and environmental performances to respond to climate changes. However, many climate projects (and business models) are currently not designed to consider adequately complex climate?related issues. In addition, there is a lack of research on assessment systems that can comprehensively evaluate business feasibility of such models. In this study, we developed a system consisting of nine major indicators in four fields to assess climate technology-based business models. Each indicator was weighed using the analytic hierarchy process (AHP) for systematic assessment of business models. The process can be utilized as a tool to guide improvement of climate technology business models.

The present study the feasibility of the new subjective assessment devise; Real-Time Subjective Assessment Digitizer (RTSAD). The subjects were instructed to evaluate their sensibility during the presentation of the positive and the negative visual stimuli using RTSAD. After the presentation of each of the stimulus, a questionnaire was used for comparing the results with those from RTSAD. It was argued that the biggest utility of the RTSAD is the capability of measuring and figuring out the trends of the subjective assessment in real time. The results from the questionnaires unlike the results from RTSAD, reflects only the averaged human sensibility for the entire time of the presentation of the stimulus.

고속도로의 확충과 산업발전에 따른 물동량 증가로 인하여 도로 구조물의 내구성 저하와 취약구간의 반복적인 하자가 발생하고 있다. 따라서 국외에서 사용하는 품질보증제도 도입방안에 대한 연구가 진행되고 있다. 국내의 경우 한국도로공사는 점검위주의 품질관리에서 목적물의 품질성능 위주의 품질관리 체계로의 전환을 위하여 목적물의 품질 수준 측정이 가능하도록 정량적 평가 지수인 품질성능지수(QPI : Quality Performance Index)를 개발하여 적용하고 있다. 품질성능지수에서 콘크리트포장 평가인자는 포장두께, 압축강도, 평탄성, 기포간격계수로 구성되어 있다. 콘크리트 평가인자의 경우 국외에서 경험적 판단에 의해 자체적으로 선정된 인자를 사용하고 있는 실정이다. 따라서 본 연구에서는 콘크리트 포장 평가인자를 수명예측 시뮬레이션 및 실측 자료를 활용하여 분석하고 평가인자의 적정성을 검토하였다. QPI의 콘크리트포장 평가인자인 포장두께, 압축강도, 평탄성, 기포간격계수는 포장수명, 공용성 및 내구성을 적절하게 판단할 수 있는 인자로 사료된다.

In this study, we investigated the site feasibility for the construction of the incineration facilities in Won Ju City. To assess the environmental impact of its construction, we examined the current status of air quality in the selected candidate sites and predicted the extent of air quality change upon its operation through modification of stack type. If the stack height is assumed to be 70 m, the concentrations of $SO_2$ and dioxin in the surrounding area were predicted to increase by 0.05 ppb and 0.09 pg/$m^3$, respectively. The impact of its operation was assessed and compared among different sites. According to this analysis, more impact was expected from the residential area for the Dan-Gye site than from agricultural areas of the Kwan-Sul and Sa-Je site.
