The Korea Electric Power Research Institute (KEPRI) has been developing planar solid oxide fuel cells (SOFCs) and power systems for combined heat and power (CHP) units. The R&D work includes solid oxide fuel cell (SOFC) materials investigation, design and fabrication of single cells and stacks, and kW class SOFC CHP system development. Anode supported cells composed of Ni-YSZ/FL/YSZ/LSCF were enlarged up to $15{\times}15\;cm^2$ and stacks were manufactured using $10{\times}10\;cm^2$ cells and metallic interconnects such as ferritic stainless steel. The first-generation system had a 37-cell stack and an autothermal reformer for use with city gas. The system showed maximum stack power of about $1.3\;kW_{e,DC}$ and was able to recover heat of $0.57{\sim}1.2\;kW_{th}$ depending on loaded current by making hot water. The second-generation system was composed of an improved 48-cell stack and a prereformer (or steam reformer). The thermal management subsystem design including heat exchangers and insulators was also improved. The second-generation system was successfully operated without any external heat source. Under self-sustainable operation conditions, the stack power was about $1.3\;kW_{e,DC}$ with hydrogen and $1.2\;kW_{e,DC}$ with city. The system also recuperated heat of about $1.1\;kW_{th}$ by making hot water. Recently KEPRI manufactured a 2kW class SOFC stack and a system by scaling up the second-generation 1kW system and will develop a 5kW class CHP system by 2010.

Purpose: This paper uses the resource-dependency theory to present the case of the Pakistan sugar industry to highlight how the industry uses a strategic alliance to gain a powerful bargaining position over its critical dependencies. The case of the Pakistan sugar industry is well-known and it is common knowledge that the alliance or the cartel within it is responsible for frequent price hikes and sugar supply shortages in the country. Research design, data and methodology: We use a case study, qualitative document analysis design to trace how the alliance overcomes its various dependencies, and in doing so, how does it harm various stakeholder interests. Results: This paper finds that the sugar industry alliance maintains its bargaining power by manipulating sugar supply through horizontal alliances, political affiliations, underselling and under-reporting sugar stocks, purchasing sugarcane from the black market, and by gaining billions of rupees in export subsidies by hoarding stock and using its political connections. Conclusion: The paper concludes by providing a summary of the measures which the government has taken to curb this anticompetitive conduct; the most important of which is the removal of protectionist measures for sugar trade and allowing market forces to control the demand and supply of sugar in the local market.

The corporate image is one of the key elements improving competitiveness of the business, and is conveyed to the public through a design management strategy and its activities with design identity. Therefore, it is important to enhance the corporate image through systematic design management. Recently, in the field of communication services, as a technical gap between corporations has been narrowed, and the importance of design has been magnified, more and more corporations have adopted the design management. It is, however, not easy to build and convey the corporate image to the public systematically, because not only do the corporations run a communication service, the corporations face various business areas and targets. In this study, we analyzed the relationship between the intended image of the corporate and users' visual experiences based on the surveys on the case of KT, which pioneered design management and has made outstanding design results. According to the result, KT's strategic image concepts have positive effects on users' visual experience in each subarea of its design identity. In conclusion, it is necessary to narrow the gap between users' experiences and images that a corporate intends to convey through continuous research on users' experiences and improvement in a design management system.

Construction designs are often produced with insufficient considerations on the constructability aspects. Poor constructability has resulted in delay, cost increase, disputes, safety hazards and inconvenience to the public. Increasingly, there has been a call for more systematic input of construction knowledge in the planning and design processes of modern day's infrastructure development. In some countries, notably the US, the practice of constructability reviews is on the rise, with concomitant benefits. It is advocated that construction plans and designs be subject to constructability reviews as early as possible. It should be made part of the project management strategy driven by the client. This paper outlines the constructability review process and benefits, whilst drawing lessons from a number of case studies.

The change of digital convergence service environment converted the subject of design into user -centric one instead of developer-centric one, and changed the existing design environment focused on product development into the new user -centric design environment. Accordingly, GUI considering user's usability come to take big shares in those contents being used for multimedia equipments. However, as the present educational contents provide complex interface due to its design produced based on the existing e-learning system, they have many problems in that they don't consider user's usability. Thus this paper aimed to analyze actual examples through GUI elements of educational contents being used for multimedia equipments and attempt to suggest some directions for development. additionally, consider the various characteristics of digital convergence environment and educational contents, and try to set up strategic directions possible to utilize user'-centric interface elements more usefully and properly at the time to produce designs.

In the past, a strategic management of work demands has been increasingly challenged to design-build (DB) firms. Such a management is capable of providing sufficient profitable impact of a project on them. Total project profit is mainly related to actual resources, work completion time, amount of rework, and costs. The degree of recycling work packages in the DB project delivery system is used as a measure of the quality of the performed work. However, there are few models available to evaluate the impact of a demand management strategy on the DB firms and to predict its behavior. We propose a decision-making support model as an aid for assessing the amount of rework and for predicting project profit resulting in a convincible demand management strategy. This model is constructed by using a dynamic feedback approach that can analyze the problems arising in complex managerial systems. For the purpose of illustration, widely acceptable strategies were applied into the model to explore their impacts on the DB firms. The results indicate that the model is helpful for the managers in selecting the most appropriate demand management strategy for successfully achieving their objectives.

Since a government design department office was set up in 2007, active design projects have been implemented. With this opportunity, each local self-governing organization has improved its administration and institutions, and are planning intensive research on public design for efficient execution of public design projects. However, recent public design projects have caused many problems due to unspecialized design processes, a lack of cooperation with relevant organizations, and unsatisfactory management systems after projects. Therefore, to overcome such problems in the execution of public design projects, a procedure-centered model should be developed. This study aims to analyse the process structures for the strategic execution of public design projects, and the methods and content of the execution process. For this purpose, this study looked into the process structures of public design projects based on design management strategies in order to draw suggestions needed for the execution process through advanced cases. The study is summed up as follows: First, when the process of public design projects was examined in terms of management strategies and design management strategies, it included two dimensions: the management structure of general projects and the design of development projects. Secondly, through the analysis of public design cases, this study discovered useful methodologies and the main programs used and drew suggestions needed for each step in public design projects. It is expected that the results of this study will be helpful for the development of a process model appropriate for national public design projects based on the current status of the project execution and to make a contribution to systematic development in national public design.
