  • The purpose of this study is to propose a scientific performance evaluation framework for measuring and managing the overall outcome of complex types of projects that are linked to public demand-based commercialization, such as information system projects and public procurement, in integrated national R&D projects. In the case of integrated national R&D projects that involve multiple research institutes to form a single final product, and in the case of demand-based demonstration and commercialization of the project results, the existing evaluation system that evaluates performance based on the short-term outputs of the detailed tasks comprising the R&D project has limitations in evaluating the mid- and long-term effects and practicality of the integrated research products. (Moreover, as the paradigm of national R&D projects is changing to a mission-oriented one that emphasizes efficiency, there is a need to change the performance evaluation of national R&D projects to focus on the effectiveness and practicality of the results.) In this study, we propose a performance evaluation framework from a structural perspective to evaluate the completeness of each national R&D project from a practical perspective, such as its effectiveness, beyond simple short-term output, by utilizing the Hourglass model. In particular, it presents an integrated performance evaluation framework that links the top-down and bottom-up approaches leading to Tool-System-Service-Effect according to the structure of R&D projects. By applying the proposed detailed evaluation indicators and performance evaluation frame to actual national R&D projects, the validity of the indicators and the effectiveness of the proposed performance evaluation frame were verified, and these results are expected to provide academic, policy, and industrial implications for the performance evaluation system of national R&D projects that emphasize efficiency in the future.

  • Recently, the Field Programmable Stateful Logic Array (FPSLA) was proposed as one of the most promising system integration technologies which will extend the life of the Moore's law. This work is the first proposal of the FPSLA design automation flow, and the approaches to logic synthesis, synchronization, physical mapping, and automatic placement of the FPSLA designs. The synchronization at each gate for pipelining determines the x-coordinates of cells, and reduces the placement to 1-dimensional problems. The objective function and its gradients for the non-linear optimization of the net length and placement density have been remodeled for the reduced global placement problem. Also, a recursive algorithm has been proposed to legalize the placement by relaxing the density overflow of bipartite bin groups in a top-down hierarchical fashion. The proposed model and algorithm are implemented, and validated by applying them to the ACM/SIGDA benchmark designs. The output state of a gate in an FPSLA needs to be duplicated so that each fanout gate can be connected to a dedicated copy. This property has been taken into account by merging the duplicated nets into a hyperedge, and then, splitting the hyperedge into edges as the optimization progresses. This yields additional 18.4% of the cell count reduction in the most dense logic stage. The practicality of the FPSLA can be further enhanced primarily by incorporating into the logic synthesis the constraint to avoid the concentrated fains of gates on some logic stages. In addition, an efficient algorithm needs to be devised for the routing problem which is based on a complicated graph. The graph models the nanowire crossbar which is trimmed to be embedded into the FPSLA fabric, and therefore, asymmetric. These CAD tools can be used to evaluate the fabric efficiency during the architecture enhancement as well as automate the design.

  • Today, businesses have to respond with flexibility and speed to ever-changing customer demand and market opportunities. Service-oriented architecture (SOA) is the best methodology for minimizing the complexity and the cost of enterprise-level infrastructure and for maximizing the productivity and the flexibility of an enterprise. Most of the enterprise-level SOA delivery strategies deal with the top-down approach, which organization has to define the business processes, to model business services, and to find the required services or to develop new services. However, a lot of peoples want to maximally reuse legacy component-based systems as well as to deliver SOA into their organizations. In this paper, we propose a bottom-up approach for identifying business services with proper granularity. It can improve the reusability and maintenance of services by considering not data I/O of components of legacy applications but GUI event patterns. Our proposed method is applied to MIS with 129 GUIs and 13 components. As a result, the valiance of the coupling value of components is increased five times and three business services are distinctly exposed. It also provides a 49% improvement in reducing the relationship problems between services over a service identification method using only partitioning information of components.

  • The Changes in management environment in SMEs such as rapid development of information communication technology, worldwide expansion of FTAs, enlargement of global outsourcing, etc have changed various aspects in industry-academy or industry-academy-government cooperation. It has been away from the cooperation focused on research and development and industrial training, and advanced to the cooperation focused on the business fields and practices where the executive ability and professionalism are required to commercialize major products of local SMEs. Compared with the existing model, the new model of industry-academy-government cooperation can provide effective and customized supports to local SMEs and expect better performance than ever before through the choice and focus. However, the existing support programs of government and related organizations are just top-down pattern to SMEs. In addition to the development of industrial technology, education and training for labor force and knowledge interchange between industry and university, the new cooperation model would also provide practical tasks such as enhancement of business competences and abilities to cultivate foreign markets. This study deals with Gyeongbuk PRIDE Products support project that is the new model of industry-academy-government cooperation and evaluates the effectiveness of this support project by empirically analyzing the survey results from the target SMEs.

  • The numbers of multi-year droughts due to climate change are increasing worldwide. Boryeong Dam, located in Chungcheongnam-do, South Korea, was also affected by a 4-year drought from 2014 to 2017. Since traditional unilateral decision making processes to alleviate drought damage have, until now, resulted in conflicts between many of the involved groups, the need for active participation from both stakeholders and policymakers is greater than before. This study introduced Shared Vision Planning, a collaborative decision making process that involves participation from various groups of stakeholders, by organizing Water Policy Council for Climate Change Adaptation in Chungcheongnam-do. A Shared Vision Planning Model was then developed with a system dynamics software by working together with relevant stakeholders to actively reflect their requests through three council meetings. Multiple simulations that included various future climate change scenarios were conducted, and future drought vulnerability analysis results of Boryeong Dam and districts, in terms of frequency, length, and magnitude, were arrived at. It was concluded that Boryeong Dam was more vulnerable to future droughts than the eight districts. While the total water deficit in the eight districts was not so significant, their water deficit in terms of spatial discordance was proved to be more problematic. In the future, possible alternatives to the model will be implemented so that stakeholders can use it to agree on a policy for possible conflict resolutions.

  • This study analysed theory and application of holistic innovation policy in the 3rd generation innovation policy with cases of Finland and Korea. Innovation policy areas of both countries are expanding from simple goal of economic development to extensive goals such as sustainable development, quality of life, balanced growth etc. Also administrative system changed in order to let technical innovation on the center of national operation and reorganized relation and structure of relative policies like manpower, education, region policy. Particularly, Korea is in embryo standing for S&T driven society since Noh's government. But, there are differences in embodiment degree and feature between both countries. Finland reinvigorate field of public opinion due to corporatism tradition as a Scandinavian institution. Government support system developed co-program and co-policy beyond territory of individual ministry to raise policy effectiveness. However, concept of the Korean innovation policy is ahead of the times but maintained framework of developing country. And there is no active participation of private sector and civil society because transition process accomplished on the top-down method, It could hardly progress toward transition in spite of various efforts to carry out a reform.

  • A city is like a living organism that is born, grows and become extinct within an ecosystem. In recent years, more and more cities have been planned by designers rather than spontaneously growing over time. This planning means that if a city is not appropriately designed at the beginning, it is very hard to fix or adjust it later. A poor urban design inconveniences many people, and forces them to adjust to it. For this reason, it is important to design a city as optimally as possible at the design phase. One of the reasons why a city is not designed optimally is complexity. Previous urban design methods have attempted to resolve the complexity by using a top-down problem-solving method based on the experience and knowledge of the urban planner. However, such an approach does not have the organic characteristics of a bottom-up problem-solving method of an artificial life, based on the creation principle of the ecosystem. Therefore, in this study the general principle of artificial life, which can provide a solution to the bigger problems that accumulate as a result of the solutions to small units of problems, is adopted. This enables us to draw various urban design alternatives, and it proves that the alternatives, despite being drawn through a limited modeling method, have almost no differences from those designed by an expert, and its possibilities of future development has also been verified.

  • Most of the SOA solutions applicable to businesses and organizations are taking a top-down methodology. It starts with an analysis of an organization's requirements, followed by definition of business models and identification of candidate services and ends with finding or developing required services. Challenges in adopting SOA while abandoning legacy systems involve time and cost required during the process. Many businesses and organizations want to gradually migrate into SOA while making the most of the existing system. In this paper, we propose A Method for Migration of Legacy System into Web Service(M-LSWS); it allows legacy system to be migrated into web service accessible by SOA and be used as data repositories. M-LSWS defines procedures for migration into reusable web services through analysis of business processes and identification of candidate services based on design specification and code of legacy system. M-LSWS aims to migrate of legacy system into web service appropriate for SOA. The proposed method consists of four steps: analysis of legacy system, elicitation of reusable service and its specification, service wrapping and service registration. Each step has its own process and guideline. The eligibility of the proposed method will be tested by applying the method to book management system.

  • Emission reduction targets to respond to climate change have been discussed and set locally, nationally and globally. After Korean government set the national target in 2009, 16 metropolitan cities established voluntary emission reduction targets by 2020. This study review and compare historical greenhouse gas emissions, reduction target by 2020 and strategies in 16 metropolitan cities. Most cities chose a consumption-based inventory approach. Some cities set the reduction target excluding land use change and forestry (LUCF) at 30% against business-as-usual by 2020, while others set the absolute reduction target against past year including LUCF. The stringency of reduction target in metropolitan cities was evaluated differently according to the comparative indicators such as the targets against BAU or past year and per capita emission, etc. Key mitigation sectors were different across metropolitan cities. It is suggested that national government share detailed raw data for metropolitan cities' emission inventory with the local government. Using advanced mitigation model and two types' target based on BAU and historical year and integrating local government's climate change plan with its energy plan are also required.

  • 수자원장기종합계획은 수자원의 안정적인 확보와 효율적인 이용 개발 및 보전을 위하여 "하천법" 제23조에 근거하여 수립되는 물 분야의 최상위 법정계획이다. 수자원장기종합계획은 20년 단위로 수립되며, 5년마다 그 타당성 여부를 검토하여 필요한 경우에는 계획을 변경하고 있다. 국토교통부는 지난 2016년 12월 수자원장기종합계획 제3차 수정계획(2016~2020년)을 수립 고시하였다. 그런데 수자원장기종합계획과 같이 상위 개념의 법정계획의 수립을 위해서는 관련 법정계획 및 부처 간의 수평적 수직적 연계가 중요한데, 현행 법체계는 이에 미흡한 측면이 있어 보인다. 우선적으로 수평적 연계를 위해서는 수자원장기종합계획 수립과정에 이수 치수 및 방재 분야의 업무를 담당하고 있는 관련 부처의 적극적인 참여를 독려할 필요가 있다. 현재 "하천법" 제23조제4항은 수자원장기종합계획을 수립하거나 변경할 경우, 중앙행정기관의 장과 협의하도록 규정하고 있다. 그러나 현행 규정에 따른 부처별 '협의'는 국토교통부가 수자원장기종합계획을 수립한 후 관련 부처의 의견을 수렴하는 소극적 형태의 협의라고 볼 수 있다. 효율적인 수자원장기종합계획 수립을 위해서는 "하천법" 소관 부처인 국토교통부가 수자원장기종합계획 수립을 위한 기본적인 지침을 수립하여 관련 중앙부처인 환경부(환경), 국민안전처(치수), 산업통상자원부(공업용수) 및 농림축산식품부(농업용수)에 시달하고, 각 부처는 담당 분야별 계획을 수립하여 국토교통부에 송달한 후, 국토교통부는 이를 취합 검토하여 수자원장기종합계획을 수립하는 적극적 형태의 연계를 고려할 필요가 있다. 수직적 연계를 위해서는 기존의 하향식(top-down)에서 벗어나 상향식(bottom-up)의 계획수립이 필요해 보인다. 즉 국토교통부의 수자원장기종합계획 수립에 따라 하위 개념의 유역종합치수계획("하천법" 제24조) 및 댐건설장기계획("댐건설 및 주변지역지원 등에 관한 법률" 제4조) 등을 수립하는 것이 아니라, 지역별 유역별로 수자원계획을 우선적으로 마련하도록 하고 이를 기초로 전 국토를 대상으로 하는 수자원장기종합계획을 수립하는 방안이 적절해 보인다. 이를 위해서는 수자원장기종합계획 수립하기 이전에 지역별 또는 유역별로 수자원계획을 수립할 수 있도록 "하천법"에 관련 규정을 신설할 필요가 있으며, 이수뿐만 아니라 환경, 방재 분야의 하위 법정계획의 수립 시기 및 주요 내용에 대한 종합적인 검토가 요구된다.
