Business reengineering (BR) is an emerging idea that attempts to restructure inefficient, current business processes through redesigning jobs and exploiting new information technology (IT), and helps achieving significant improvements in white-collar productivity and returns of IT investment. This research analyzed order-taking and purchasing processes of a company (a coil distributor) using BR concepts, models and principles. We also made proposals for reengineering the present business processes. For this, BR literatures were reviewed to derive BR models and principles to be used for analyses. We applied these ideas to six(6) types of order-taking and purchasing processes of Company T. For each type, current processes, BR analyses, and proposals for BR were described. Finally, findings were summarized and discussed.

Customer population management models can be classified into three categories: the first category includes the models that analyze the customer population at cohort level; the second one deals with the customer population at aggregate level; the third one has interest in the interactions among the customer populations in the competitive market. Our study proposes a model that can analyze the dynamics of customer population in consumer-durables market at aggregate level. The dynamics of customer population includes the retention curves from the purchase or at a specific duration time, the duration time expectancy at a specific duration time, and customer population growth or decline including net replacement rate, intrinsic rate of increase, and the generation time of customer population. For this study, we adopt mathematical ecology models, redefine them, and restructure interdisciplinary models to analyze the dynamics of customer population at aggregate level. We use the data of previous research on dynamic customer population management at cohort level to compare its results with those of ours and to demonstrate the useful analytical effects which the precious research cannot provide for marketers.

Content services for silver users on the ubiquitous technologies are getting attention as a new business model, monitoring users in real-time on the real-world and/or cyber-world. A lot of business and service model have been developed to apply silver or elder user. This study explained a state-of-the-art silver IT service to innovative services for users, ranging from home and finance to support for healthcare and living. Due to the variation of subtle terminologies, this study was conducted to restructure an adaptive terminology including some definitions. Current silver IT service model has been evaluated from the technical, functional, and business analyst, and its suitability has also been expressed in a proposed model and service. The purpose of this study was to propose a systematic approach of new IT service business model for silver users. A proposed model was described to explain the feasibility of the silver IT industry.

Interstate electric power system, as an alternative for energy cooperation under regional economic bloc, has been hotly debated before progressing the restructure in electric power industry and rapidly expanded in many regions after 1990s. Especially, since northeast asia has strong supplementation in resource, load shape, fuel mix etc., interconnection of electric power systems in this region may bring considerable economic benefits. For the economic analysis, we implement ORIRES model developed by ESI, Russia. ORIRES is a linear programming (LP) model for electric power system operation and planning. Since ORIRES requires data relatively less than other model, it is suitable for northeast asia that has considerable restriction against required data acquisition. In this paper, we perform an economic analysis on interconnection in northeast asia.

Interconnection of electric power systems, as an alternative for energy cooperation under regional economic bloc, has been under extensive debate before progressing the restructure in electric power industry and rapidly expanded in many regions after 1990s. Especially, since northeast asia has strong supplementation in resource, load shape, fuel mix etc., electric power system interconnection in this region may bring considerable economic benefits. In this paper, we evaluate economic benefits from CO2 emission abatement and effectiveness on the fuel mix in Korea by the interconnection in northeast asia. For this analysis, we evaluate effects of CO2 emission abatement under various system interconnection scenarios and compare the results of fuel mix in Korean electric power system with and without transacted electricity via interstate electric power system in northeast asia.

Public procurement for innovation is used as one of the major policy tools to stimulate innovation and promote growth of small and medium-sized enterprises (SMEs) in Korea. However, it is evaluated that this policy has not been so effective in promoting technological innovation among SMEs largely because it heavily depends on price competitiveness of SMEs products and services. In order to draw some policy implications, this study examines the PPI policies of selected countries as comparative references and conducts an empirical analysis on Korean Public Procurement Services (PPS) data for identifying challenges of the current policy in Korea. We conclude that in order to enhance technological innovations of SMEs, PPI policy in Korea should 1) focus more on the potential competitiveness of SMEs, 2) enlarge public demands especially on R&D services, 3) encourage private sector participation in the public procurement market, 4) improve the assessment criteria for public procurement market registration, and 5) restructure the responsible organizations.

Purpose: Now a day, Most of the residential house in Korea consists of apartment buildings. However, in the case of old apartment buildings, dwelling environment condition depends on management effort by residents. But we can't rebuild or restructure only old single dwelling unit in apartment buildings. And we can't move every single dwelling unit in the apartment building. Therefore, this study suggests a prototype of combinable container dwelling module apartment. Method: The method of research is exploring the case of previously constructed containers. Based on the case, This study suggests prototypes to create a variable apartment design with dwelling container units. Based on the prototype, various combinations are proposed to produce various types of dwelling space. Finally, this study makes an example plan for the apartment by using the container unit modules. Results: This study suggests combinable container apartment building prototypes. And it may be a fundamental study of changing the apartment building concept.

Additional analyses on the environmental impact of the system interconnection, and sensitivity of key factor inputs have been performed.

The purposes of the study were to identify the present status of the agricultural extension services in Korea and its surrounding environment, and to search the desirable ways of improvement under the serious restructuring period occurred by the nation-wide localization, globalization and development of information technology. Agricultural extension services have made great accomplishment in the education for rural people and agricultural technology diffusion, but agricultural extension service system no longer well fits in the changed environment. Agricultural extension services in Korea should restructure the system, function and methods in order to cope with the changing technology and rural society. The objectives of the extension services should be clear and simplified so that the extension workers can understand their role and duty more clearly. The local governments should encourage the extension workers to carry out their services diligently and with the pride. Also, the extension workers should change their mind to fit in the changing world and should improve their capability for their services.
