The subject this paper is the signal control strategy under oversaturated conditions. The nature of traffic control for oversaturation is essentially different from the standard control modes. While under non-saturated situation traffic control is needed for the sake of safety and efficiency, the throughput is essential under oversaturated conditions. Therefore berth objective and strategies differ. For an oversaturated stream the cycle time and the signal offset are thought to be of rather secondary importance. For this case the green split may well be the most important control variable to serve the excessive demand. Up to now, however, most efforts have concentrated on the strategy with the concept which lies just on the extension of Webster's. "Green-split Coordination Strategy for Over-Saturated Networks", presents newly contrived three types of strategies named Forward-coordination, Backward-coordination and Network-coordination respectively and describes the algorithms with the evaluations. The forward coordination strategy treats the forward wave of flow between two signals. The aim is to prevent the outbreak of queue due to the accumulation of temporary excess of demand in near-saturation or saturation flow. The backward coordination strategy treats the backward rave of flow between two signals. The goal is to prevent the waste of green time caused by the exit block at the upstream signal. for this purpose a feedback regulation is provided of the upstream green-split so that the inflow-outflow balance is kept zero. The resultant surplus of green time is alloted to other signal stages. Also here the examination is made of the appropriate value of the feedback control parameter. The network coordination strategy is operated to maximize the network throughput in a specific direction applying a bang-bang control at the bottleneck intersection. This is a type of intervenient control for policy reasons. For this strategy the green-split coordinations, particuarly the backward coordination, are essential as the tactical elements. In order to evaluate the preposed strategies those are compared with the latest existing strategy called saturation-degree-ratio control by the simulation experiments in an assumed 4$\times$4 grid network. The results are satisfactory showing a 10-15% reduction in delays and a 15% increase in network capacity.

The UK is a service superpower with solid and well-developed financial and insurance services, including FinTech. Much of the UK's service industry is digital and becoming increasingly so. Primary sources constituting the UK's comparative advantage in services could be factored in business conditions driving innovation in the digital age and world-leading digital competitiveness. Therefore, this study examined the UK's digital policies. This research's focal strands were the UK's digital strategy, national artificial intelligence strategy, and digital trade objectives. As an essential insight for policymakers and other stakeholders, this study proposes that government policies in response to the digital economy are inextricably linked, leading to a critical driver for the UK's digital competitiveness.

Introduction of BIM(Building Information Modeling) was led by public institutions, and all buildings over a certain size were obligated to apply BIM. However, through various attempt to apply BIM to actual practice, people had doubt whether it is a usable technology in reality appeared. Therefore, this study investigated cases about implementation strategies of foreign countries, and conducted survey on BIM performances and preparation in architectural design firms. On the basis of this, it suggests the long-term development strategy of BIM and the basic direction of road map to adopt BIM effectively to domestic architectural design market. After considering the cases abroad and the results of survey, it is identified that incentive policies supporting finance and education should be carried out together with partially obligation method led by government in order to introduce BIM into architectural design market effectively by reflecting current situation of architectural design firms.

Recently, the green business/IT-related issues such as $CO_2$ emission and energy consumption have become spread out rapidly through the world. EU, the United States, Japan and other developed countries are using IT-related environmental regulations as trade barriers. Korea which has high rate of IT exports needs to establish systematic strategies to respond to these environmental regulations. However, it is not easy to find the related research about making green business/IT strategies. This research aims to deduce the green business/IT strategy framework and the suitable green business/IT strategies for the Korean situation. The green business/IT strategy framework is constructed from the analysis of preceding researches and those of the green business/IT strategies of Japan, the United States, and EU. The Korean green business/IT strategies are deduced from survey of experts using Delphi method. We expect that the results contribute to establish the systematic policy and action plan to reduce $CO_2$ emission and energy consumption of IT industry.

Many of logistics-related research in automobile industry has focused on inbound logistics and procurement. Research into outbound logistics is relatively few. As a starting research into outbound logistics in automobile industry, this paper examined its logistics network problems with three aspects - location strategy, inventory strategy and transportation strategy. We proposed alternatives of logistics network design resolution, and presented three practical scenarios based on those alternatives. Based on interview, on-site visit and internal data collection processes, we identified major domestic outbound logistics problems such as redundant logistics bases, inefficient delivery policy, insufficient inventory capacity, inventory stock quality deterioration, inefficient transportation system, and etc. In order to cope with those problems, we proposed such strategic alternatives as introduction of hub-and-spoke system, integration of logistics bases, introduction of (automatic) parking building, diversification of transportation mode, and etc. At the same time, we constructed three practically executable scenarios based on those ideas. The first is "Center Hub" scenario, the second is "Metropolitan Hub" scenario. The third and last scenario is "Regional Consolidation of Warehouses (distribution centers)".

Investment in FA facilities has been accerelated since 1986, turning point by labor strife in Korea firms. Most commonly adopted automation tech, in their manufacturing process consists of NC. Robotics, PLC, CAD/CAM now on and further confused system oriented FMS, CIM, etcs. undergoing. But for all their remarkable notices in manufacturing systems, The competitive position on product cost, quality, shorten delivery and profit has never been recovered in global swing market. To make some empirical suggestions with a view to competitive strategy of Korea firms by FA, to the conclusion largely FA tech. adoption can be justified only when its application on new product productions and improved the structure of products comparatively. Because of when it was applied in old production process. The effectiveness is very doubtful to the lacks of consistent and integrate manufacturing policy with the strategy of the fim and their poor standardization level in shop floors.

This study attempts to define IT high-level human resources and to investigate past IT high-level human resources development (HRD) policies in order to promote IT HRD policy efficiently. Benchmarking implications were derived from comparative studies of foreign high-level HRD policies and we suggest IT high-level HRD Policy in the framework of National Future Strategy. The results of this study are rich in implications for implementation of IT HRD related to national R&D road-map in the field of information technology, the supply spread maintenance and the vision change of high-level HRD to cultivate global competitiveness, IT-based Fusion Technology HRD, and R&D related HRD policies and action plans.

South Korea had encouraged farmers to breed bear to increase farmer's income since 1981. Currently farmers breed over thousand number of bears, however but the policy measures for breeding bears is expected to conflict the main stream of bear conservation due to South Korea belong to the member of CITES, which categorizes and manages bears under Wild Fauna and Flora Protection Act. Government needs to establish a special law containg the win-win relief strategy not only for farmers of breeding bears, but international corresponding policy. So, we have reviewed the domestic status and international trends on breeding bears, and suggest the alternative strategies of the policy such as a bear park, a bear village, use of species recovery center, use of a preservation organization. This policy should be accompanied with more detailed fact analysis, management agency, well equipped welfare facility and financial preparation for proper management of breeding bears against changing international trends on wildlife conservation.

The value chain of a country is achieved in cooperation with other countries. Accordingly, the international technical cooperation in the field of R&D is known to be one of the innovation strategies. But the efforts on research in the international technological cooperation is lacking in Korea. Europe expects technological progress in the industrial area in order to create employment in the near future but Science and Technology Research should also create this endeavor for the future. EU recognizes that the current trend of scientific and technological research will have a negative impact on future job creations in Europe. Therefore EU has developed the 2020 strategy. The purpose of this paper is to seek the technological cooperation policy especially on the basis of the EU's 2020 strategy. In accordance with the results of this paper, our government will pursue future EU FP 8 policy to be developed on the basis of EU's 2020 strategy.
