국민소득 증가와 고령화 사회에 진입하면서 다양한 의료소비가 의료서비스산업에 영향을 미치고 있으며, 이러한 사회 구조 및 환경변화에 따라 새로운 질병에 대한 대응 또한 절실히 요구되고 있다. 질병 예측을 위한 연구는 기후변화와 질병, 건강행태와 질병, 사회적 위치와 질병 등 질병에 영향을 주는 많은 요인들이 있다. 그러나 이러한 요인들을 통합, 분석 활용하는 데는 해결해야 할 문제들이 많이 있다. '정부3.0 공공데이터 개방 정책' 을 통해 질병에 관련된 자료가 공개 되면서 본 연구에서는 2010년부터 2012년까지의 질병에 영향을 주는 공공데이터를 연도별로 통합하여 지리정보시스템(GIS)기반 데이터베이스를 구축하고 활용 할 수 있게 하였다. 향후 기후변화에 민감한 질병을 찾기 위해 해당기관의 자료를 활용하여 월별로 데이터베이스를 구축하고, 이를 기반으로 의료서비스의 활성화 및 효율성에 기여 할 수 있다.

This paper presents a business models of the robot industry for copying with aging society that facilitates to create new business opportunities in the convergence age. In order to identify the market drivers for both convergence and aging society, the trends of them analyzed. Through constructing and analyzing market value chain, we design a set of the business model of the robot industry focused on u-health robots of a convergence service type integrated ubiquitous, health and robot. In addition, we describe the evolution path of the proposed business model in terms of technology development and market. Finally, we develop a matrix based evaluation framework to measure and assess the effectiveness of the business model.

Digital convergence which means the convergence of industry areas related to digital technologies is an important phenomenon in business, which will decide the fates of firms in the near future. The only firms which can create synergy effects from digital convergence are expected to be the winners in the fierce competition of digital convergence era. In our analysis, we examine the strategy of an integrated firm which has businesses in two different industry areas which are related to each other. By using a game theoretical model, we show how the integrated firm can win over two single separated firms which have business in only one industry area each by leveraging the two businesses the integrated firm has. In our welfare analysis, we also show that this convergence may be even beneficial to consumers, which seems counter-intuitive to social concerns about anti-competitive behaviors by integrated firms. Additionally, we study comparison between industry convergence and product convergence.

The information and communications construction business has the characteristics of an infrastructure industry and responsibility for the construction and maintenance of all ICT infrastructures. With the recent proliferation of the smart convergence of various industries based on ICT infrastructure, the role of the information and communications construction business has been highlighted to accommodate the convergence and implementation environment in construction and medical industries. Therefore, this paper seeks policy measures to establish the new role of the information and communications business under the rapidly developing smart convergence environment and the priorities of policy measures to strengthen the capability of the information and communications business using a quantitative model. The analysis result suggests that the difference in importance of each policy measure should be considered in order to execute effectively the policy of promoting the information and communications construction business. Given the constraint of limited budget, policy priorities include the development of new markets, and establishment of incentive for new technology. This study is significant for its theoretical contribution, being the first quantitative approach to policy priorities for the promotion of information and communications construction business under the smart convertgence environment.

This study investigates the convergence of the optimal consumption and investment policies in a binomial-tree model to those in the continuous-time model of Merton (1969). We provide the convergence in explicit form and show that the convergence rate is of order ∆t, which is the length of time between consecutive time points. We also show by numerical solutions with realistic parameter values that the optimal policies in the binomial-tree model do not differ significantly from those in the continuous-time model for long-term portfolio management with a horizon over 30 years if rebalancing is done every 6 months.

This study investigates the effects of convergence firefighter helmet attributes on consumer attitude toward the product and willingness-to-pay. The results of empirical analysis are as follows. First, consumer attitude toward the convergence product is more favorable when conciseness, economical efficiency, and the utility value of the convergence product's attributes are high, while consumer attitude toward the convergence product is less favorable when the perceived risk of the convergence product's attributes is high. Second, consumer willingness-to-pay for the convergence product is higher when conciseness, economical efficiency, and the utility value of the convergence product's attributes are high, while consumer willingness-to-pay for the convergence product is lower when the perceived risk of the convergence product's attributes is high. Based on our results, the implications are discussed for the further development of convergence products.

This study examines how the characteristics of cooperative research and development (R&D) projects in the public domain impact information and communication technology (ICT) convergence. Based on the analysis of 416 cooperative R&D projects under the ICT-based industry convergence R&D program in Korea, the study finds that the characteristics of cooperative R&D projects significantly impact ICT convergence. Moreover, the participation of public research institutes and universities is critical for ICT convergence compared with that of firms. However, in firm-to-firm cooperation, the participation of small and medium enterprises contributes to cross-sectional convergence, while the participation of large firms leads to overall and longitudinal convergence. R&D inputs such as the number of partners and government subsidies exhibit an inverted U-shaped relationship (negative quadratic effect) with technology convergence. Project duration and homogeneous partners are also critical factors for ICT convergence. The results indicate several implications and guidelines on how to effectively organize cooperative R&D projects to facilitate technology convergence.

In this paper, we proposed the next generation mobile convergence service business model creation methodology. In order to establish such a business model creation methodology framework, we first introduce the service model based on our previous research results on next generation mobile convergence services. The service model contains several components such as infrastructures, operations, and provision of services that are indispensible for providing the next generation mobile services. Finally, by adding service and value flows to the developed service model, we propose the next generation mobile services business model creation methodology. To achieve this objective, we first derive necessary components of business model including actors, their relationships, and roles. In addition, we propose service composition methodology for creating new mobile services and its corresponding business models.
