An efficient method is developed for classifying fingerprint data based on 2-D discrete wavelet transform. Fingerprint data is first converted to a binary image. Then a multi-level 2-D wavelet transform is performed. Vertical and horizontal subbands of the transformed data show typical energy distribution patterns relevant to the fingerprint categories. The proposed method with moderate level of wavelet transform is successful in classifying fingerprints into 5 different types. Finer classification is possible by higher frequency subbands and closer analysis of energy distribution.
u-City 건설사업 시나리오에 따른 건설기업의 대응전략 수립에 관한 연구

u-City건설사업은 최근 건설사업이 창출할 수 있는 새로운 부가가치 영역으로서, 건설기업이 신시장을 개척하기 위해 적극적으로 도전해야 될 분야로 주목받고 있다. 하지만, 건설기업의 입장에서는 u-City건설시장의 주도권을 IT업계에서 선점하고 있으며, 관련 연구 개발이 IT분야의 주도로 추진되고 있다는 점 때문에 u-City 건설시장에 선뜻 참여하지 못하고 있다. 따라서 본 연구에서는 u-City 건설사업과 관련하여 제기되고 있는 불확실성 요인들을 개요화하고 각 불확실성 변수별로 그 방향성을 분석하여 개연성 있는 시나리오를 도출하였고, 이를 기반으로 각각의 시나리오 상황에 대응하기 위한 건설기업의 전략적 방향을 제시하였다. 이를 통하여 건설기업의 시장분석 및 전략수립의 기초자료로 활용할 수 있게 하며 결과적으로 u-City 건설사업에의 건설기 업의 참여를 유도하고자 한다. The u-City construction project has become a hot topic In the construction market because it seems economic value-added field for construction firms. However, construction firms don't willingly participate in the u-City construction market because the future business environments for the u-City are very uncertain. Scenario planning is a very powerful method in managing this complex planning situation and is based on scenarios that help each enterprise appropriately adapt itself to its own business environments. Therefore it Is based on the main principles of systems thinking and multiple futures. For the purpose of dealing with such uncertainties, this paper attempts to develop the possible market scenarios of the u-City construction market through a scenario planning approach. From this perspective, we considered various aspects of the u-City construction such as market demands, technology development, policy level and management environment. After considering the relevant issues, we identified the main trends and key uncertainties. Then, we developed three coherent u-City construction market scenarios. On the basis of the proposed scenarios, the business strategies of potential construction firms in the u-City construction market has been formulated. Therefore, construction firms can use these scenarios as a basic data for market analysis and business strategy. Therefore, this paper is able to enhance the participation of construction firms in the u-City construction market.
