Numerous stationary NO_x emission sources have employed a suitable deNO_x technology that is typically selective catalytic reduction (SCR) of NO_x by NH₃ over V₂O₅/TiO₂-based catalysts with on-demand monolithic structures. These structured catalysts undergo a time-on-deterioration of deNO_xing activity on site. Thus, we need more efficient, more deactivation-tolerant, more economic deNO_x systems and for which, their performance management is essential. This review has covered details of strategies to successfully manage the performance of SCR catalysts and timely replace them to new or rejuvenated ones. Key considerations to maintain the catalyst activity will be reviewed. Details of the sequential addition of new catalysts and the replacement of life-end catalysts and their regeneration will be discussed with general guidances to determine the time for such a replacement. Finally, a better way to get more economic approaches to deNO_x system management will be proposed here.

The recent movement toward the better environment urges the shift of pollution prevention strategy from traditional "command/control" and "end-of-pipe" technologies to clean technologies. Development of Clean Technology, which makes products without creating pollutions, is a way to solve Environmental problems fundamentally. The main objective of this study is to define the long-term strategy to develope "Innovative Clean Technology". "Innovative Clean Technology" is an active way of solving the environmental problems arising from industrial activities. It aims to find ways either to make products without creating pollution, to produce environmentally benign end-products, or else to recover and re-use the materials which have hitherto considered waste.

Companies have to take agility against change of environment and build up the capacity of new value creation in today's management environment. Until now, there are so many management method for efficiency of management, rationality of management and IT (information technology) supported this method by integration of enterprise task and process automation. but company's competitiveness through the efficiency of management realized the limitations recently. so companies needs the new management method to raise core value of enterprise. This study applies strategy intelligence which is some part of Business Intelligence. We can identify the core value driver by using this method. and the core value driver is connected the KPI (key performance indicator) of processes in BPM (Business Process Management). This help the management of process focused on value driver. and some part of activity driver that effect the process performance can be use the Six Sigma method to strategic business process. This study first introduces the concept of Business Intelligence, Business Process Management and Six Sigma. and then efficient connection plan for value based strategic business process is introduces.

In the 21st century, the Information Revolution caused unpredictable kinds of complications. Human society conducts a tactical network war like Swarming. Network war simultaneously consists of merits such as global monitoring and anti-dictatorship campaign, and violent demerits like terrorism. It has been becoming a generalization of terrorism of the present time to build a brotherhood and ideology to commit terrorism. This is considered as new terrorism, a form of network war. Theses days, terror organizations including Al Qaeda establish a brotherly network to commit terrorism when and where they want. New terrorism is a novel form that harms unspecified individuals. In fact, many countries have been experiencing damage from new terrorism. It is becoming an urgent issue to every country to prepare a suitable plan that cope with new terrorism. This dissertation provides defense strategy in macro and micro aspect as a responding scheme to new terrorism.

Real-time traffic information disseminated through VMS is known to have effects not only on driver to plan a route choice, detour the congestion, and cope with incident, but also on VMS operator to manage the traffic volume indirectly. But, the dissemination of traffic information is operated in the side of provider, not of user. Importance-Performance analysis (IPA) offers a simple, useful method for simultaneously considering both the importance and performance dimensions when evaluating or improving strategy. This technique has been successfully used in a variety of settings to define priorities and guide resource optimization decisions. This study uses IPA to evaluate traffic information strategies through VMS to make resource improvement recommendations. It gained 760 samples by field surveys, which are conducted in Korean Thanksgiving Day, weekday and weekend at the service areas of expressways. The results indicate that the motivations in quadrant I (concentrate here) are dissemination of exactly information and quick transmission, while distance of VMS, most drivers are not satisfied with that is located in quadrant III (low priority).

It is very difficult for ordinary people to commit suicide bombing because of two reasons. First off, suicide bombers have to sacrifice themselves. Moreover, suicide bombers should kill innocent people who are not directly related to their goals. However, suicide bombing increase and 2,670 people were killed in 2011 due to suicide bombing. Ropoport indicated that suicide bombing is related to the fourth wave in modern terrorism. This study explored the current situation of suicide bombing and analyze suicide bombers' motivation with several cases. The suicide bombers' motivations were explained by two categories, which are individual and organizational(or social) aspects. The individual aspect included the loss of family, trauma, and distorted recognition of society. The organizational(or social) aspect consisted of religion, ideology, and strategy. It was found that these aspects influence suicide bombing. There was no suicide bombing in Korea, but we need to prepare for suicide bombing because of high possibility.

Since the launch of WTO. the global telecommunications market has been accelerated to ensure interoperability between the various telecommunications or services and this effort is emerging as the realization of an importance of standardization. In addition, in recent years as standardization is recognized not as just a means of ensuring interoperability but as a key strategic means of economic survival in the new trade order at the international regional, and national levels. Thus, each country is working actively to process telecommunications standardization through such means as multilateral cooperation and collective counter-strategies, which are mapped out, in the various regional and global fora and consortia. In keeping with these trends, Asia-Pacific Telecommunity, which is taking charge of telecommunications affairs of Asia-Pacific region, has been pursuing not only regional common interests but enhancement of its status in the world market by standardization on the basis of intimate collaboration, obtained by establishing regional standardization organization named ASTAP(APT Standardization Program). Bearing in mind the consideration outlined above, this paper aims to analyze telecommunications standardization policy intended by Asia-Pacific regional standardization organization and accordingly, to suggest a strategy for strengthening telecommunications standardization activities in Asia-Pacific region.

산업혁명 이후 인간사회의 산업화 및 도시화의 가속으로 지구온난화는 기후변화를 야기해 왔으며, 이로 인한 각종 부정적인 영향과 심각성은 날로 커져가고 있는 현실이다. IPCC(Intergoverment Panel on Climate Change)는 기후변화의 주범인 온실가스를 감축할 지라도 기후의 탄성 때문에 앞으로 수세기 이상 계속 진행될 것으로 전망하였으며, 기후변화 영향의 근원적 방지는 불가능하기 때문에 결국 수자원 관리 측면에서도 기후변화에 적응하기 위한 각종 적응전략 개발의 필요성을 강조하였다(IPCC, 2007). 또한, 극한강수의 발현비율이 도시 및 비도시 지역의 구분 없이 과거 30년에 비해 크게 증가하고 있으며 이러한 추세는 수공구조물의 치수안전도 저하에 큰 영향을 준다. 우리나라는 그동안 하천, 유역 홍수저감 시설물과 댐 등 대형 수공구조물에 대한 안전성 평가를 주기적으로 수행해 왔으나 단순히 모니터링을 통하여 현재의 안전기준의 부합 여부만을 판단하는 수준에 그치고 있다. 장래 증가하는 홍수피해에 대처하기 위해서는 다양한 극한강우 및 극한홍수시나리오를 기반으로 시설물 설계기준별 홍수 위험도와 취약성을 평가하고, 극한홍수 방어기준을 재설정하여 현재 설계기준을 제고할 필요가 있으며, 시설물별 안전도 평가와 위험도 저감계획 및 경제성 평가를 종합적으로 고려한 실행프레임워크 개발이 시급한 실정이다. 따라서 본 연구에서는 도림천 유역에 대하여 최적화된 도시유출모형을 통하여 기후변화가 도시유역에 미치는 유출영향을 분석하였으며, MCS(Monte Carlo Simulation)을 통한 극치수문사상의 적용 및 유출분석을 통한 하천제방의 취약성 평가와 위험도 분석을 실시하여 도시하천의 기후변화 영향을 정량적으로 표현하고자 하였다. 또한 기후변화에 따른 도시하천의 수문특성 변화분석 결과를 바탕으로 향후 발생할 수 있는 극치 수문사상의 값을 반영한 설계기준 강화 수방시설 계획 등의 연구에 활용하며, 여러 가지 수문학적 불확실성에 의하여 가변 가능한 도시하천 유역의 취약성 평가 및 위험도 분석을 통한 기후변화 대응과 수공구조물 설계 및 수방전략 수립에 활용하고자 한다.

산업혁명 이후 인간사회의 산업화 및 도시화의 가속으로 지구온난화는 기후변화를 야기해 왔으며, 이로 인한 각종 부정적인 영향과 심각성은 날로 커져가고 있는 현실이다. IPCC(Intergoverment Panel on Climate Change)는 기후변화의 주범인 온실가스를 감축할 지라도 기후의 탄성 때문에 앞으로 수세기 이상 계속 진행될 것으로 전망하였으며, 기후변화 영향의 근원적 방지는 불가능하기 때문에 결국 수자원 관리 측면에서도 기후변화에 적응하기 위한 각종 적응전략 개발의 필요성을 강조하였다(IPCC, 2007). 또한, 극한강수의 발현비율이 도시 및 비도시 지역의 구분 없이 과거 30년에 비해 크게 증가하고 있으며 이러한 추세는 수공구조물의 치수안전도 저하에 큰 영향을 준다. 우리나라는 그동안 하천, 유역 홍수저감 시설물과 댐 등 대형 수공구조물에 대한 안전성 평가를 주기적으로 수행해 왔으나 단순히 모니터링을 통하여 현재의 안전기준의 부합 여부만을 판단하는 수준에 그치고 있다. 장래 증가하는 홍수피해에 대처하기 위해서는 다양한 극한강우 및 극한홍수시나리오를 기반으로 시설물 설계기준별 홍수 위험도와 취약성을 평가하고, 극한홍수 방어기준을 재설정하여 현재 설계기준을 제고할 필요가 있으며, 시설물별 안전도 평가와 위험도 저감계획 및 경제성 평가를 종합적으로 고려한 실행프레임워크 개발이 시급한 실정이다. 따라서 본 연구에서는 SEEP/W 모형을 이용하여 일반적인 하천 제방을 바탕으로 침투해석을 실시하여 그 결과를 이용하여 안정성 평가에 대하여 검토하였다. 또한 기후변화에 따른 도시하천의 수문특성 변화분석 결과를 바탕으로 향후 발생할 수 있는 극치 수문사상의 값을 반영한 설계기준 강화 수방시설 계획 등의 연구에 활용하며, 여러 가지 수문학적 불확실성에 의하여 가변 가능한 도시하천 유역의 취약성 평가 및 위험도 분석을 통한 기후변화 대응과 수공구조물 설계 및 수방전략 수립에 활용하고자 한다.
