The public SW market is 3 trillion won, which is less than 10% of the total SW market. However, due to the nature of the domestic market, it is an important market with a relatively large impact on small and medium-sized software companies. In this market, government is operating the Public SW Project Demand Forecasting System in order to support the marketing activities of small and medium sized SW companies and establish a fair market order. The current system has limitations such as lack of user convenience, insufficient analysis capability and less business connection. This study was conducted to identify the problems of these systems and to propose a new system for improving the convenience of users and expanding the information utilization of SMEs. To this end, we analyzed the requirements of each stakeholder. We proposed the 2-phased forecasting cycle, the management cycle, and the system life cycle of public SW projects and created a unified identifier (UID) so that the information of those projects can be identified and linked among them. As a result, an integrated reference model of project information management based on system life cycle was developed, which can explain the demand forecasting and project information, and the improved processes was also designed to implement them. Through the result of this study, it is expected that integrated management of public SW projects will be possible.

2009년 11 월 KT의 애플사의 스마트폰인 아이폰(i-phone)의 국내 도입과 함께 촉발된 국내 스마트폰시장의 확산은 2010년 구글을 중심으로 삼성전자, SKT등 기존 대기업들의 갤럭시폰을 비롯한 OS기반의 스마트폰을 선보이면서 스마트폰 가업자가 2010년 말까지 약 600만병에 이를 것으로 전망된다. 이러한 스마트폰의 확대와 함께 2009년말 기업, 하나은행 등 일부 은행들이 처음 스마트폰뱅킹을 시작한 이례 2010년 상반기, 이미 국내 대부분의 시중은행들이 아이폰용 iOS를 비롯한 주요 스마트폰의 OS 플랫폼을 기반으로 한 스마트폰뱅킹 서비스를 제공하고 있다. 그러나 금융산업의 특성상, 금융거래의 신뢰성과 안정성 측면에서의 개인정보보호 및 금융정보안과 관련한 법규가 채 정비되지 않은 가운데 국내 은행들은 스마트폰뱅킹 출시경쟁에 치중한 나머지 보안 및 개인정보보호에 대한 대책수립은 미흡하며 정부당국의 정보보호관련 지침에 의존, 고객의 자발적인 주의에 호소하고 있는 설정이다. 이처럼 스마트폰뱅킹의 도입이 활발히 진행되면서 금융 서비스 혁신 등 기술적 편의성외에도 개인정보보호를 위한 보안 및 법적 안정성의 중요성이 높아지고 있다. 본 논문은 국내 은행의 스마트폰뱅킹 현황과 고객정보보호 및 관리에 대한 법률적 고찰과 규제환경 변화를 중심으로 국내 은행의 스마트폰뱅킹 도입에 따른 고객정보보호 방안을 제시하고자 한다.

Estimating the sales price of a residential building development project is difficult because of it has many complex variables such as location, environment, and economic conditions. Many previous studies related to influence factors of the sales price is to identify by survey of experts and it is few studies by comparing with actual sales price. Accordingly, the purpose of this study is to identify the factors influenced on the projects by using correlation analysis from collected actual data in this study. For the purpose, first, the factors such as economy, location, housing, financial environmental factors were identified from previous studies. Second, data were collected on actual sale prices and selected factors. Finally, the actual sales price and factors were compared and analyzed by using correlation analysis. As a result, the R² values of economy, location, housing and financial environmental factors were over 0.5 respectively. Therefore, it was confirmed that these factors were significantly correlated with actual sales price. The results of this study are expected to be utilized as basic data for research and development of a new sale prices prediction model.
