  • The widespread concern regarding the management of spent fuel that mainly contributes to nuclear waste has led to the development of the sodium-cooled fast reactor (SFR) as one of the most promising future types of reactors at both national and international levels. Various reactor deployment scenarios with SFR introductions with different conversion ratios in the existing PWR-dominant nuclear fleet have been assessed to optimize the SFR deployment strategy to replace PWRs with the view toward a reduction in the level of spent fuel as well as efficient uranium utilization through its reuse in a closed fuel cycle. An efficient reactor deployment strategy with the SFR introduction starting in 2040 has been drawn based on an SFR deployment strategy in which burners are deployed prior to breakeven reactors to reduce the amount of PWR spent fuel substantially at the early deployment stage. The PWR spent fuel disposal is reduced in this way by 98% and the cumulative uranium demand for PWRs to 2100 is projected to be 445 ktU, implying a uranium savings of 115 ktU. The SFR mix ratio in the nuclear fleet near the year 2100 is estimated to be approximately 35-40%. PWRs will remain as a main power reactor type until 2100 and SFRs will support waste minimization and fuel utilization.

  • Patient education is one of the most important roles of a physical therapist. Physical therapists have to teach and provide information about illness, instruct for home exercise, and give advice relating to correct posture and daily activities et al. For an efficient education some strategies are required. The purpose of this article is to review general learning methods, to introduce elements that influence the procedure of patient education and learning, and to plan an education strategy.

  • We investigate rate scheduling and power allocation problem for a delay constrained CDMA systems. Specifically, we determine an energy efficient scheduling policy, while each user maintains the short term (n time slots) average throughput. More importantly, it is shown that the optimal transmission strategy for the uplink is same as that of the downlink, called uplink and downlink duality. We then examine the performance of the optimum transmission strategy for the uplink and the downlink for various system environments.

  • The purpose of this paper is to investigate the development strategy for the Hub of Northeast Asia. Those countries such as Singapore, Taiwan, Hong Kong and China competing us are trying to concentrate on their core capacity. Based on the severe competition surrounding us, we are confronting with a transitional period to upgrade competitiveness. It is acknowledged that the building of economic hub of Northeast Asia is essential to become an advanced country. Therefore, it is becoming an urgent task that Korean government should formulate the development strategy of building efficient transportation network, economic special zone and financial hub.

  • The various research on Communities of practices (CoP) for propagation of softer type knowledge in new Knowledge Management (KM) strategy having been performed for past couple of years. CoP is one of effective process innovation tool for diffusion of knowledge. Based on CoP's voluntary and spontaneous characteristic, it performs a function of delivering softer type knowledge of workers to the other colleagues of organization. But one step further to CoP's function of propagation of internal knowledge, research on function of CoP's contribution in enterprise strategy are insufficient yet. This paper presents enterprise CoP should be managed and aligned to strategic objectives of enterprise, and also, suggests the methodology for CoPs to maintain a lifecycle as a tool to contribute in strategic goal attainment. Although CoPs are voluntary and spontaneous informal organization, it can display a contribution as tool for KM strategy when it is aligned to strategy properly and form efficient lifecycle.

  • Nowadays, domestic hospital business is under the great threat from the environmental changes caused by the entrance of foreign hospitals and the technical changes related to information systems. In such a situation, to enhance the competitive edge of a hospital, it is needed to set up a competitive strategy and to construct an efficient information systems to back up the competitive strategy. If the hospital information systems(HIS) is consistent with a competitive strategy backing up, the competitive force of a hospital will be enhanced. For this respect, the influence of the competitive strategy and HIS construction environments on the performance of HIS was examined. The results suggested that if a HIS should be newly constructed or should be restructured, it is necessary to select construction environments of HIS such as physical environments, development methods and development tools to support functional strategy effectively based on the competitive strategy adopted by a hospital.

  • Indigenous innovation is the main strategy for China during 2006 - 20 period. China may hope that indigenous innovation policy will spur on industrial upgrading. The purpose of this paper is to evaluate the indigenous innovation policy. The paper begins with the background of the strategy, follows the detailed content of the national strategy, then analyzes how the strategy is implemented. We find that the package of indigenous innovation policy is constructive and efficient for a catch-up economy with clear industry targets but not good for innovation. If China want to be an innovative country, it needs to give market competition more space to incubate and eventually yield increment or disruptive innovation, even radical innovation. Chinese enterprises cannot close themselves off to the global technology system. Only open innovation can give Chinese enterprises the possibility to win in the next wave of innovation in the world and make China an innovative country.

  • A series hydraulic hybrid vehicle(SHHV) concept has been explored as a potential pathway to an ultra-efficient city vehicle. Improvements in SHHV fuel economy with reduced emissions strongly depend on their supervisory control strategy. Thermostatic control is simple and reliable but it's cause of frequent engine on-off. Therefore, power follower strategy is presented. In this paper, thermostatic control strategy and power follower strategy is compared for the SHHV model developed using AMESim.
