본 연구는 상품추천을 위해 필요한 고객선호도 추정모형을 제안하고, 이러한 선호도 추정결과에 따른 선호도 정보를 이용하여 궁극적으로 상품추천의 성과를 제고시키기 위한 방법을 제시하였다. 즉, 고객의 행동패턴만으로 고객의 제품선호도를 정확히 추정할 수 있는 새로운 선호도 추정모형을 제안하였다. 이 제안모형은 선호도에 영향을 주는 요인들의 상대적인 가중치를 학습을 통해 최적화시킴으로써, 보다 정확한 선호도 평가를 가능하게 해 주다. 한편, 이 모형의 타당성을 검증하기 위해서 본 연구에서는 가상서점 고객들을 대상으로 고객선호도 정보를 수집한 후, 본 제안모형을 적용했을 때의 협업 필터링 성과와 단순선호도 계산식을 이용했을 경우의 성과를 비교 분석하였다. 이에 대한 실증분석결과는 본 제안모형을 적용했을 때의 협업 필터링 성과가 단순 선호도 모형을 적용했을 때의 성과보다 더 우수한 것으로 나타났다.

Recently, some universities and university libraries have implemented performance management system as a part of managerial innovation, and they have either implemented or are considering implementing BSC. Thus there are needs to develop performance indicator, which is a tool measuring performance of university libraries, based on BSC, and to assess the developed performance indicator's relative weights to analyze which indicators are essential to fulfill and improve the university library's mission. The performance indicators are also affected by the characteristics and perspectives of the people who develop them during the development process. Therefore, it is necessary to analyze the differences among the professional groups in relative weighting of the performance indicator. The purposes of this study are to derive a university library performance indicator model based on BSC, to analyze the importance of each evaluation factor of the derived performance indicator model, and to analyze the differences among the professional groups in relative weighting of the performance indicator model.

IT분야에 대한 정부의 각종 R&D사업 수행 시 과제 선정 및 연구결과에 대한 평가의 투명성, 객관성 및 효율성을 확보하여 사업의 신뢰성을 확보하고 성과를 제고하여야 한다. 1999년 대학기초연구지원 사업에 시범적으로 적용한 전자평가시스템 개발 내용과 그 결과를 위원회 평가와 비교 분석하였다. 1999년에 처음 시도한 전자평가시스템은 과제 제안자 관점에서는 과제접수가 용이하고, 과제 공고부터 결과 정리 시 소요되는 총 소요기간 단축으로 과제 선정을 조속히 확정 가능하여 대민 서비스 제고 차원에서 유용한 평가시스템으로 판단되며, 과제 관리 차원에서도 총 평가비용의 30% 정도의 예산절감 및 10배정도 업무량의 감소 효과를 주는 것으로 분석되었다. 이와 같은 결과를 바탕으로 전자평가시스템이 적용 가능한 사업을 발굴하여 점진적으로 확대 적용하는 것이 타당하며 향후 추진 과제로 산업체가 제안하는 과제내용이 제안자 동의 없이 외부로 유출 방지 등 검토가 필요하다.

The purpose of this study is to establish the Balanced Score Card for 'I Company' which is a small and medium sized manufacturing company in Busan City. It is suitable for SMEs and suitable for the management environment. The study was intended to contain the detailed needs of managers and employees when developing the performance measurement system. It also allowed other SMEs to benchmark through this study. We also proposed a solution to the problems after BSC construction. In addition, BSC has been developed for the purpose of shifting business strategy from RDS to SSS in accordance with changes in the demand market environment. Strategy Maps were divided into the whole company level and each team level. You can look at strategic goals, core success factors, and key performance indicators at each glance. Finally, we developed a smart performance evaluation system that can easily calculate the score, strategic goal, key success factor, weight of key performance indicators, target score, performance, and achievement rate by creating a smart chart. Have significance.

Recently, as economic property it has become necessary to acquire and utilize the framework for water resource measurement and performance management as the property of water resources changes to hold "public property". To date, the evaluation of water technology has been carried out by feasibility study analysis or technology assessment based on net present value (NPV) or benefit-to-cost (B/C) effect, however it is not yet systemized in terms of valuation models to objectively assess an economic value of technology-based business to receive diffusion and feedback of research outcomes. Therefore, K-water (known as a government-supported public company in Korea) company feels the necessity to establish a technology valuation framework suitable for technical characteristics of water resources fields in charge and verify an exemplified case applied to the technology. The K-water evaluation technology applied to this study, as a public interest goods, can be used as a tool to measure the value and achievement contributed to society and to manage them. Therefore, by calculating the value in which the subject technology contributed to the entire society as a public resource, we make use of it as a basis information for the advertising medium of performance on the influence effect of the benefits or the necessity of cost input, and then secure the legitimacy for large-scale R&D cost input in terms of the characteristics of public technology. Hence, K-water company, one of the public corporation in Korea which deals with public goods of 'water resources', will be able to establish a commercialization strategy for business operation and prepare for a basis for the performance calculation of input R&D cost. In this study, K-water has developed a web-based technology valuation model for public interest type water resources based on the technology evaluation system that is suitable for the characteristics of a technology in water resources fields. In particular, by utilizing the evaluation methodology of the Institute of Advanced Industrial Science and Technology (AIST) in Japan to match the expense items to the expense accounts based on the related benefit items, we proposed the so-called 'K-water's proprietary model' which involves the 'cost-benefit' approach and the FCF (Free Cash Flow), and ultimately led to build a pipeline on the K-water research performance management system and then verify the practical case of a technology related to "desalination". We analyze the embedded design logic and evaluation process of web-based valuation system that reflects characteristics of water resources technology, reference information and database(D/B)-associated logic for each model to calculate public interest-based and profit-based technology values in technology integrated management system. We review the hybrid evaluation module that reflects the quantitative index of the qualitative evaluation indices reflecting the unique characteristics of water resources and the visualized user-interface (UI) of the actual web-based evaluation, which both are appended for calculating the business value based on financial data to the existing web-based technology valuation systems in other fields. K-water's technology valuation model is evaluated by distinguishing between public-interest type and profitable-type water technology. First, evaluation modules in profit-type technology valuation model are designed based on 'profitability of technology'. For example, the technology inventory K-water holds has a number of profit-oriented technologies such as water treatment membranes. On the other hand, the public interest-type technology valuation is designed to evaluate the public-interest oriented technology such as the dam, which reflects the characteristics of public benefits and costs. In order to examine the appropriateness of the cost-benefit based public utility valuation model (i.e. K-water specific technology valuation model) presented in this study, we applied to practical cases from calculation of benefit-to-cost analysis on water resource technology with 20 years of lifetime. In future we will additionally conduct verifying the K-water public utility-based valuation model by each business model which reflects various business environmental characteristics.
