원전 일차계통 HyBRID 제염공정에서 발생되는 제염폐액에는 황산이온과 방사성 핵종을 포함한 금속이온 및 발암성 물질의 하이드라진을 포함하고 있어 이를 안전한 수준으로 처리할 수 있는 기술개발이 필요하다. 본 연구에서는 모의 제염폐액 내 황산 및 금속이온의 제거와 하이드라진의 분해시험을 실시하여 황산이온, 금속이온 및 하이드라진을 효과적으로 제거할 수 있는 HyBRID 제염폐액 처리공정을 도출하였으며, 1 L 규모에서의 반복실험과 Pilot 규모(300 L/batch)에서의 평가시험을 통해 도출한 HyBRID 제염폐액 처리공정의 성능 재현성과 적용성을 검증하였다.

Performance evaluation has been done using financial indices which are generally regarded as inappropriate for the organizations which are innovative and progressive. Thus, the Balanced Scorecard(BSC) was developed considering long term performance and invisible performance. This BSC has four perspectives of finance, customer, internal operation, and learning. Based on the BSC, a new BSC has been derived with a fifth view of environmental and social perspective, which is now called as a Sustainability BSC. In this study, we evaluated Green IT initiatives using the Sustainability BSC. The initiatives are categorized as RFID, telepresence, paperless office, logistics management etc. The initiatives were evaluated from the view of five perspectives, resulting in high cor relationships among finance, internal operation, and environmental and social perspectives. Namely, good initiatives from the view of environmental/social perspective are also evaluated as good from the view of finance and internal operation perspectives. In this study, we recommend organizations to introduce Green IT initiatives by showing how Green IT initiatives have contributed to the organizations.

Many systems using RFID/USN were and are being developed. Some systems are used in practice and some are not. Generally, the main reasons not being used are: The prices of chips are too high considering the effects. The application domain is not appropriate for RFID/USN. So, various skills for higher sensing precision have been introduced like using multiple sensors and avoiding metals which deter sensings seriously. Now, it is time to evaluate systems which were developed using RFID/USN technology. However, no systematic approach has been made for the evaluation. In this paper, a framework using BSC is introduced for the evaluation of systems using RFID/USN. In this framework, some Critical Success Factors(CSF) are derived and some Key Performance Indices(KPI) are developed for each CSF.

We don't have time to waste, time is running, and the global warming is an issue that concerns to all of us. Information technology, which on a global level is responsible for 2% of emission of greenhouse gases. However, the remaining 98% is seen as an opportunity for IT to help our planet, our companies and our society. The purpose of this paper is to analyze green information technology (IT) initiatives and their strategic impact. And to have done this, we develope and create a very useful balanced-scorecard framework to explain, understand, and identify the direct and indirect contribution of green IT initiatives. The green IT evaluation framework, called here a sustainable green IT balanced scorecard, integrates the four BSC-IT perspectives with the Zuboff's automate/informate goals of information systems and the contribution of the sustainability (economic, social and environment). This study also seeks to answer the following questions: 1) what are the driving forces for implementing green IT initiatives? 2) How can an analytical framework be built to systematically analyze the benefits and strategic contribution of green IT initiatives? And 3) how green IT initiatives impact the strategic goals of a firm and how they can contribute to the triple bottom line? The framework demonstrates to be useful as a management tool to hopefully integrate environmental and social management with the general management of a company. Besides, the strategy map and measures for each cell of the framework are provided.
