The value of universities in driving economic development has been understood for a long time. However, with the increasing importance of the 'science-entrepreneurship' relationship in giving science its modern economic value there is growing interest in how this dynamic can be enhanced. One of the strategies that has been widely adopted has been the creation of research-science-technology parks although commonly these projects were being established prior to the theoretical approaches that justify their development. This paper reports on a study that measured the financial value of the links between the University of Surrey and tenants on its Surrey Research Park project and also looks forward at strategies being adopted by the University concerning the continuous improvement of its technology transfer offering to increase the value of these links and put some empirical data behind the claims of the value of research-science-technology parks as part of a wider innovation strategy.

Poor logistical infrastructure and agri-food supply chain management leads to significant food waste in logistic system. The concept of the sustainable value added agri-food chains requires defined approach to the analysis of the existing situation, possible improving strategies and also assessment of these changes impact on further development. The purpose of research is to provide scientific substantiation of theoretical and methodological principles and develop practical recommendations for the improvement of the agri-food logistics distribution system. A case study methodology is used in this article. The research framework is based on 4 steps: Value Stream Mapping (VSM), Gap and Process Analysis, Validation and Improvement Areas Definition and Imitation Modelling. This paper presents the appropriateness of LEAN logistics tools using, in particular, Value Stream Mapping (VSM) for minimizing logistic losses and Simulation Modeling of possible logistics distribution system improvement results. The algorithm of VSM analysis of the agri-food supply chain, which involves its optimization by implementing the principles of sustainable development at each stage, is proposed. The methodical approach to the analysis of possible ways for optimizing the operation of the logistics system of the agri-food distribution is developed. It involves the application of Value Stream Mapping, i.e. designing of stream maps of the creation of the added value in the agri-food supply chain for the current and future state based on the minimization of logistic losses. Simulation modeling of the investment project on time optimization in the agri-food supply chain and economic effect of proposed improvements in logistics product distribution system functioning at the level of the investigated agricultural enterprise has been determined. Improvement of logistics planning and coordination of operations in the supply chain and the innovative pre-cooling system proposed to be introduced have a 3-year payback period and almost 75-80% probability. Based on the conducted VSM analysis of losses in the agri-food supply chain, there have been determined the main points, where it is advisable to conduct optimization changes for the achievement of positive results and the significant economic effect from the proposed measures has been confirmed. In further studies, it is recommended to focus on identifying the synergistic effect of the agri-food supply chain optimization on the basis of sustainable development.

An accruable point scenario study was applied to examine the effect of the point-accumulation trend (diminishing vs. increasing) and the nominal value (small vs. large) of a medium for repeated consumption on program loyalty. The results showed that both factors affect consumer loyalty toward a reward program. Consumers who received a medium with an increasing accumulation trend and a large nominal value perceived a reward to be more valuable than those who received a diminishing trend and a small nominal value. The results confirmed that a large nominal value or an increasing accumulation trend increased the perception of reward and program loyalty. However, when the desirability of the medium was controlled, the effect of trend was reduced to almost negligible whereas that of the nominal value remained the same. These findings suggest how consumer perceptions of loyalty programs can be practically managed through point accumulation processes.

Objective: To evaluate the effects of sit-to-stand (STS) imagery group training (IGT) on STS movement and balance performance for chronic hemiparetic stroke. Design: Randomized controlled trial. Methods: A total of 30 people with chronic hemiparetic stroke (15 for STS-IGT group and 15 for control) were recruited in this study. The STS-IGT group participated in a videotape-based STS-IGT for 30 minutes a day, five days a week for six weeks, while the control group watched a documentary on television for the same period. The STS-IGT focused on a five-stage protocol. Specifically, external imagery was used during the four phases of the STS movement from the seat of the chair to standing up. All of the participants also participated in a regular rehabilitation program. STS movement and balance performance were assessed using three clinical measures. Results: After training, time to perform the 5-repetition STS test significantly increased in the STS-IGT group (change value, $4.0{\pm}2.0$ sec) compared with the control group (change value, $0.9{\pm}0.7$ sec) (p<0.05). There was a greater improvement in Berg balance scale scores in the STS-IGT group (change value, $0.2{\pm}4.1$ points) compared with the control group (change value, $0.3{\pm}0.9$ points) (p<0.05). There was a greater improvement in Timed Up and Go scores in the STS-IGT group (change value, $2.6{\pm}1.5$ sec) compared with the control group (change value, $0.9{\pm}1.0$ sec) (p<0.05). Conclusions: STS-IGT can be considered as a useful option for restoration of STS movement and balance performance for individuals with chronic hemiparetic stroke who are unable to fully participate in physical activities.

This study was surveyed from May to October, 2008 in order to classify type distribution and evaluate the function of inland wetland as a ecological axis in Chungnam province. Assessment was done by modified-RAM (Rapid Assessment Method). RAM is consisted of total 8 functions and divided into high, moderate, low. The conservation grade of RAM is divided into 4 grades; absolute conservation, conservation, improvement and restoration. Throughout survey on total 13 wetlands of Lacustrine, Palustrine wetland which are distributed in Chungnam province, their function was assessed. As result, the 2 wetlands were judged as absolute conservation grade by assessment of 8 functional contents, and 7 sites were improvement wetlands and 4 sites were conservation wetlands. The function of wetlands assessed as conservation grade showed high in water quality protection and improvement. Also, showed high in vegetation diversity, wildlife habitat and aesthetic recreation. Meanwhile, showed low in Water quality purification, Shoreline/Stream Bank Protection. Of wetlands evaluated as conservation grade, Jeong-juk Ji and Dun-ri reservoir were assessed as absolute conservative area. These wetlands are essential to be managed continuously as a area having high ecological value. Farther, these wetlands will be done as a axis of ecological network related to 'Kumbuk jeongmaek' ecosystem.

The uncertainty assessment is important to improve the reliability of emission inventory data. The DARS (Data Attribute Rating System) have recommended as the uncertainty assessment technic of emission inventory by U.S. EPA (Environmental Protection Agency) EIIP (Emission Inventory Improvement Program). The DARS score is based on the perceived quality of the emission factor and activity data. Scores are assigned to four attributes; measurement/method, source specificity, spatial congruity and temporal congruity. The resulting emission factor and activity rate scores are combined to arrive at an overall confidence rating for the inventory. So DARS is believed to be a useful tool and may provide more information about inventories than the usual qualitative grading procedures (e.g. A through E). In this study, the uncertainty assessment for 2009 CAPSS (Clean Air Policy Support System) emission inventory is conducted by DARS. According to the result of this uncertainty assessment, the uncertainty for fugitive dust emission data is higher than other sources, the uncertainty of emission factor for surface coating is the highest value, and the uncertainty of activity data for motor cycle is the highest value. Also it is analysed that the improvement of uncertainty for activity data is as much important as the improvement for emission factor to upgrade the reliability of CAPSS emission inventory.

A multi-objective design exploration for a three-element airfoil consisted of a slat, a main wing, and a flap was carried out. The lift curve improvement is important to design high-lift system, thus design has to be performed with considered multi-angle. The objective functions considered here are to maximize the lift coefficient at landing and near stall conditions simultaneously. Kriging surrogate model which was constructed based on several sample designs is introduced. The solution space was explored based on the maximization of Expected Improvement (EI) value corresponding to objective functions on the Krigingmodels. The improvement of the model and the exploration of the optimum can be advanced at the same time by maximizing EI value. In this study, a total of 90 sample points are evaluated using the Reynolds averaged Navier-Stokes simulation(RANS) for the construction of the Kriging model. In order to obtain the information of the design space, two data mining techniques are applied to design result. One is functional Analysis of Variance(ANOVA) which can show quantitative information and the other is Self-Organizing Map(SOM) which can show qualitative information.
