It is well-known that a kind of wheel drive mechanism is usefully employed in various service robots. One of the essential requirements for such robots is regarded as the capability of climbing that enables them to run on an inclined road smoothly. So, this paper considers the capability of climbing in a wheel drive robotic mechanism and proposes a necessary discriminating condition to determine the specification of a driving actuator which will be employed. Consequently, it is expected that the proposed discriminating condition can be applied to wheel drive robotic mechanisms in the design aspect.

Recently, many software companies are trying to improve the software quality and project outcome with more costs and efforts in development time. In the software convergence and integration environments, it is required efforts to gain high quality of software. In other words, it is required to utilize software engineering knowledge and technology for higher software quality and better software project productivity. The Software development productivity can be varied by software process capability according to building a framework for software development, selection and use of appropriate technology, human resource management. Software process capability will influence software project outcome which is the general opinion. This study provides empirical evidence about software engineering efforts and investment approach to lead software project performance. We measured the software engineering efforts by SW engineering level and analyzed the corelation between software engineering level and schedule deviation. And, we verified that this performance is affected by the size of software company. As a result, software process capability is important to build a infrastructure and develop systematically software project. The higher software engineering level can lead to improved software project performance.

The purpose of this study is to investigate how software policy shows the moderating effects between organizational capability maturity and organizational performance. The software policy includes the proportions of development personnel and development budget that can affect organizational performance. It is important to empirically identify whether the ratios of budget and personnel, which are some of the main policy indexes of the organization can promote the causal relationship between organizational maturity and organizational performance. These personnel and budget may be assumed to affect the causal relationship between organizational capability maturity and organizational performance. The results of this study shows that the moderating effects of software policy are partially proved. The two policy indexes, personnel ratio and budget ratio, showed a moderating effect between process implementation and organizational performance, but did not show any moderating effect between quantitative management and organizational performance. This is because the companies participating in the survey are still in the early stages of quantitative process management and quantitative management does not show the differentiated results among the participating organizations. The significance of this study is as follows. In the academic aspect, the causal relationship between organizational maturity and organizational performance was examined empirically, and it was analyzed whether the two adopted policy indicators have a moderating effect between organizational maturity and organizational performance. On the practical side, the analysis suggested that the ratios of budget and personnel emphasized by the government or organization played a role of facilitating the organizational maturity and organizational performance.

This paper provides the results of performance investigation of gas insulated switches(G/S) for distribution power system. In order to investigate anti-contamination capability of G/S we carried out electrical tests and material analysis on the body of G/S and it's accessories. Through this experiment we found out the lead cable of G/S had not anti-contamination capability and G/S had insufficient interval between each phase. In order to improve the performance of G/S for heavy contamination area it is indispensable to replace the lead cable to the new cable which has anti-contamination ability.

This study was initiated to inquire as to why Wal-Mart failed in the Korean market. For multi-national corporations, environmental differences such as cultural and social differences among countries require business strategies to vary country by country. In Korea, Confucian Ethics are penetrated in every aspect of people's lives. An important aspect of Confucian Ethics is the role and responsibility of women in society. Considering this, businesses need to understand Korean women's preferences as consumers and develop business strategies accordingly. This study emphasizes that IS strategy is one component of the business strategy and, as such, must be rooted in business issues. Understanding that IS strategy should fit to national contexts, this study investigates the underlying process in which IT-based strategic capability is developed according to national context to gain competitive advantages.

This paper proposes a Direct Power Control (DPC) scheme of improved command tracking capability for Permanent Magnet Synchronous Generator (PMSG) Medium Voltage (MV) Wind Turbines. Benchmarking is performed based on a neutral point clamped three-level back-to-back type voltage source converter. It is introduced to design the DPC modeling and propose DPC scheme of a three-level NPC (3L-NPC) converter. During the fault condition in wind farms, the proposed control scheme directly controls the generated output power to the command value from the hierarchical wind farm controller. The proposed control scheme is compared with conventional control scheme as respect to loss and thermal analysis. The DPC scheme of improved command tracking capability is confirmed through PLECS simulations. Simulation result shows that proposed control scheme achieves a much shorter transient time in a step response of generated output power. The proposed control scheme makes it possible to provide a good dynamic performance for PMSG MV wind turbine to generate a high quality output power under grid fault condition.

This research proposes a conceptual framework to highlight the importance of change management after firms implement ERP systems. With ERP, firms need to rework their business processes to make information flow smoothly within organizations. Firms cannot realize expected returns from ERP investments unless changes are effectively managed after ERP systems are put into operation. The research model is empirically tested using data collected from over 170 firms that had used ERP systems at least for more than one year. Our analysis reveals that the eventual success of ERP systems depends on effective change management after ERP implementation, supporting the existence of the 'valley of despair.
