This research proposes a new approach to measure corporate contributions to sustainability called Sustainable Value. With some global corporations which recognize the seriousness of environmental crisis and their social responsibility, enterprises are positively accepting the sustainable management. Also, publication of the sustainability report is proliferating which is showing the enterprise's strategy, activity, result and influence in environmental, economic, social cases to the stakeholder. However, to settle and proliferate this current, it rests with how to evaluate enterprises sustainability in reasonable and reliable figure. In this context, what introduced and taking effects are sustainability report evaluation and awarding system. But the quality of sun stainability report and its content's depth and the evaluation of enterprise's sustainability itself should be distinguished. Because the enterprise which published excellent graded sustainability report is not always the enterprise that is sustainable. Then, how could we prove the result of enterprise's sustainable management based on sustainability report? This paper is to find the answer and to utilize it based on sustainability report, particularly sustainable value model as the central figure.

Real-time embedded systems should accommodate many kinds of hardware platforms and resource management policies that vary depending on their operating environments and purposes. It is not an easy job to adapt a multitasking kernel to new system services and hardware platforms, as the kernel must strictly satisfy constraints on its size and performance. This paper describes the design and implementation of an object-oriented multitasking framework that can be reused for implementing microprocessor-based real-time embedded multitasking kernels, In this kernel framework, those parts that can vary depending on hardware platforms and system resource management policies are separated into the hot spots and encapsulated by abstract classes. Our framework thus can be effectively used to implement microprocessor-based real-time embedded kernels that demand high portability and adaptability.

This study attempts to find the relationship between achievement of environmental industry and development of financial sector by analyzing cross-sectional data for OECD countries. Development of financial industry has a positive effect on environmental industry. Green financing also affects improvement of environmental quality. Demand for environmental quality is positively influenced by GDP per capita, while financial crisis has a bad effect on environmental performance. Government-led green financing in Korea has a major role in the Korean environmental policy for years. While market-oriented green financing improves the efficiency of regulation, government-led green financing may delay internalization of environmental cost due to its subsidizing effect. Further study should include systematic analysis on the scope of green financing and its qualitative attribute and fundamental causality between green financing and environmental improvement.

This study tends to apprehend how much public library contributes to a role of upbuilder of digital integrated local society through a survey. For this, I performed the survey on 935 organization of public library in the whole country registered in national library statistical system. As a result, firstly, it's apprehended that equipment infra, Internet infra, etc like computer, laptop, scanner, tablet PC, etc are in relatively high level. Secondly, service or resource like electronic book, digital and virtual reference service, library service mobile App, etc that users can use are in relatively high level but software supporting cooperation and group task, fusibility of participating space, etc are shown very low level. Thirdly, the rate of literacy training relating to technology were only 22.4%, education subject focused on resource searching subject and somewhat future-oriented technical education like directions of video conference technique, cloud computing application education, etc wasn't conducted. Finally, we should consider expansion of providing technology and equipment and provision of future-oriented service and education according to a flow of the time that needs to seek change in various roles of library as enjoying culture space or creative space.

The World Wide Web has become the largest virtual system that is almost universal in scope. In recent research, it has become effective to utilize idle hosts existing in the World Wide Web for running applications that require a substantial amount of computation. This novel computing paradigm has been referred to as the advent of global computing. In this paper, we implement and propose a mobile object-based global computing framework called Tiger, whose primary goal is to present novel object-oriented programming libraries that support distribution, dispatching, migration of objects and concurrency among computational activities. The programming libraries provide programmers with access, location and migration transparency for distributed and mobile objects. Tiger's second goal is to provide a system supporting requisites for a global computing environment - scalability, resource and location management. The Tiger system and the programming libraries provided allow a programmer to easily develop an objectoriented parallel and distributed application using globally extended computing resources. We also present the improvement in performance gained by conducting the experiment with highly intensive computations such as parallel fractal image processing and genetic-neuro-fuzzy algorithms.

이제 더 이상 지구 온난화는 나만 혹은 우리를 제외한 남의 일이 아닌 것이다. 거의 매일 우리는 지구 온난화로 인한 난처한 현상들을 보고 듣거나 직접 느끼고 있는 중이다. 지구 온난화의 주 원인인 이산화탄소 가스의 배출은 비록 다양한 배출 요인들로부터 비롯되고 있다지만 무엇보다도 과다한 생산 제조 활동 때문이라는 것을 모르는 사람은 거의 없을 것이다. 과다한 생산 제조 활동의 증가 추세가 둔화되지 않는 것을 지속적인 신규 생산 제조 활동으로부터 비롯되는 것이라 생각할 수 있다. 이를 막을 수 있는 방안은 말이 쉽긴 하나 재활용 더 나아가 재사용하는 길 뿐이다. 사실상 재활용 역시 상대적으로나 적은 범위의 국한된 생산 제조 활동일 뿐이지 이산화탄소 가스의 배출은 역시 원천적으로 차단하기가 거의 곤란하다. 결국은 재사용의 선택만이 효과적으로 이를 최대한 억제할 수 있는 바른 길이 될 수 있을 것이다. 한편, 최근에 들어서 이른 바 눈에 보이지 않는 자원 전쟁의 분위기가 전세계적으로 고조되고 있는 실정이다. 희귀 금속 자원을 보유하고 있지 않는 국내의 경우는 전반적으로 산업 분야에 걸친 생산 제조 활동에서 요구되고 있는 부품 소재용 원천 금속 자원을 매년 막대한 외화를 지불하며 종속적으로 중국 등의 국가들로부터 수입에 의존하고 있다. 이 또한 매년 일정한 수입 량이 보장되지도 않을 뿐만 아니라 해마다 관세가 높아져 여간 골치 아픈 일이 아니다. 따라서 생산 제조 활동을 주로 하여 수출에 많은 기대를 하고 있는 OECD 국가의 일원인 구내의 경우에는 환경적인 측면과 경제적인 측면을 동시에 고려한 이른바 에코지향형 생산 제조 활동을 더욱 심도있게 추구할 당위성이 제기된다. 이 중의 하나가 바로 생산 제조 활동의 주역을 이루는 매개체 중의 일원인 에코융합형 신개념의 절삭 공구라고 할 수 있다.

The service oriented architecture (SOA) is gaining more momentum with the advent of Web services on internet. A programmable and machine accessible Web is the vision of many, and might represent a step towards the semantic Web. However, security is a crucial requirement for the serious usage and adoption of the Web services technology. This paper proposes design goals for an distributed access control model for CPC(Collaborative Product Commerce). It then design a processor model for CPC components, along with web services standard and concept that can be used as a basis to design an access control processor independent of a particular CPC service implementation.
