본 논문에서는 생물체의 세포 내에 존재하는 방대한 객체들 사이의 복잡한 관계들로 표현되는 상호작용 네트워크를 효율적으로 구축할 수 있는 시스템을 제안한다. 이 시스템은 바이오 도메인 지식을 사용하여 상호작용 네트워크를 관리 및 활용하기 쉽도록 구축하고, 단백질과 같은 단순 바이오 객체뿐만 아니라 여러 개의 바이오 객체들로 구성된 복합 객체도 관리 할 수 있다. 여기서, 사용자가 바이오 객체들과 이들간의 복잡한 상호작용 관계를 직관적으로 정의 할 수 있는 인터페이스를 제공한다. 또한, 정의된 객체 및 상호작용 관계 정보를 이용하여 바이오 네트워크를 개념적으로 단순하게 표현할 수 있으며, 시각적으로도 네트워크를 자동으로 최적화하여 사용자가 복잡한 네트워크를 쉽게 분석 할 수 있도록 지원한다.

단백질 상호작용 네트워크에는 단백질들로 구성된 패스웨이와 콤플렉스 등과 같은 의미 있는 바이오 컴포넌트들이 존재한다. 하지만, 단백질 상호작용 네트워크는 방대한 단백질들과 상호작용 관계들로 구성되어 있고 많은 잘못된 정보들을 포함하고 있다. 따라서, 사용자가 정확한 단백질에 대한 식별자로 구성된 질의를 통해 원하는 바이오 컴포넌트를 탐색하는 것은 쉽지 않다. 본 논문에서는 사용자가 원하는 바이오 컴포넌트를 식별자뿐만 아니라 단백질 및 상호작용 관계의 다양한 특징들을 이용하여 탐색할 수 있는 방법을 제시한다. 또한 단백질 상호작용 네트워크에는 잘못된 정보들이 많이 포함하고 있으므로 주어진 질의와 근접하게 일치하는 결과들도 제시할 수 있는 질의 연산자들을 제공하여 보다 다양한 관점에서 검토할 수 있도록 하였다.

This study attempted to analyze technology convergence structure and key technology research sectors in bio-health. For this, network analysis was performed based on the patent outcomes achieved through national R&Ds. Then, a patent network was analyzed to derive problems and collect data from the National Science & Technology Information Service. With the five groups obtained through the analysis of IPC network and national R&D patents in bio-health based on a research frame network, topics were chosen based on the bio-healthcare technology system. Then, the technology with the greatest ripple effects was derived and compared to other sectors, suggesting a direction for national R&D investments. It is anticipated that this study would make a contribution to a search for R&D investment direction by additionally analyzing overseas patent data and improving correlation analysis between technology convergence and government-led R&D expenses.

최근 인터넷에 의한 전자 상거래, 전자 정부 등 정보통신 인프라가 널리 보급되고, 이를 통한 서비스가 보편화됨에 따라 패스워드나 PM을 대신할 수 있는 바이오인식 기술에 대한 관심이 증대되고 있다. 하지만, 개방형 네트워크 환경에서 바이오 인식 기술은 바이오 정보의 유출/오용 등 기존 시스템에서와 다른 문제들을 내포하고 있다. 특히, 비밀 번호나 PM과 같이 사용자가 임의로 변경할 수 없으므로 외부로 유출된다면 심각한 문제가 발생할 수 있다. 본 고에서는 개방형 네트워크 환경에서 바이오 인식 기술이 어떠한 종래 기술들과의 융합을 통해 발전해 가는지 살펴본다. 이를 위해, 스마트카드, 암호화 기술 및 DRM기술 등 관련 기술과의 융합 예를 참조하여 발전 모델을 소개한다.

The bio-Sensors, which are sensing the vital signs of human bodies, are largely used by the medical equipment. Recently, the sensor network technology, which composes of the sensor interface for small-seize hardware, processor, the wireless communication module and battery in small sized hardware, has been extended to the area of bio-senor network systems due to the advances of the MEMS technology. In this paper we have suggested a design and implementation of a health care information system(called u-EMS) using a bio-sensor network technology that is a combination of the bio-sensor and the sensor network technology. In proposed system, we have used the following vital body sensors such as EKG sensor, the blood pressure sensor, the heart rate sensor, the pulse oximeter sensor and the glucose sensor. We have collected various vital sign data through the sensor network module and processed the data to implement a health care measurement system. Such measured data can be displayed by the wireless terminal(PDA, Cell phone) and the digital-frame display device. Finally, we have conducted a series of tests which considered both patient's vital sign and context-awared information in order to improve the effectiveness of the u-EMS.

As fossil fuels are depleted worldwide, alternative resources is required to replace fossil fuels, and biofuels are in the spotlight as alternative resources. Biofuels are produced from biomass, which is a renewable resource to produce biofuels or bio-chemicals. Especially, in order to substitute fossil fuels, the research focusing the biofuel (biodiesel) production based on CO₂ and biomass achieves more attention recently. To produce biomass-based biodiesel, the development of a supply chain network is required considering the amounts of feedstocks (ex, CO₂ and water) required producing biodiesel, potential locations and capacities of bio-refineries, and transportations of biodiesel produced at biorefineries to demand cities. Although many studies of the biomass-based biodiesel supply chain network are performed, there are few types of research handled the uncertainty in CO₂ supply which influences the optimal strategies of microalgae-based biodiesel production. Because CO₂, which is used in the production of microalgae-based biodiesel as one of important resources, is captured from the off-gases emitted in power plants, the uncertainty in CO₂ supply from power plants has big impacts on the optimal configuration of the biodiesel supply chain network. Therefore, in this study, to handle those issues, we develop the two-stage stochastic model to determine the optimal strategies of the biodiesel supply chain network considering the uncertainty in CO₂ supply. The goal of the proposed model is to minimize the expected total cost of the biodiesel supply chain network considering the uncertain CO₂ supply as well as satisfy diesel demands at each city. This model conducted a case study satisfying 10% diesel demand in the Republic of Korea. The overall cost of the stochastic model (US$ 12.9/gallon·y) is slightly higher (23%) than that of the deterministic model (US$ 10.5/gallon·y). Fluctuations in CO₂ supply (stochastic model) had a significant impact on the optimal strategies of the biodiesel supply network.

This study is a numerical representative modelling analysis for applying the process that unravels networks between cells in genetics to Network of informatics. Using the probabilistic graphical model, the insight from the data describing biological networks is used for making a probabilistic function. Rather than a complex network of cells, we reconstruct a simple lower-stage model and show a genetic representation level from the genetic based network logic. We made probabilistic graphical models from genetic data and extend them to genetic representation data in the method of network modelling in informatics.

Firm’s social network has been known as an important firm strategy because it could promote technological innovation and also minimize economic uncertainty. In this study, we identify four types of firm’s social network activities such as Collaboration, Manufacturing/Marketing/Distribution Agreements, Financing, and M&A, and analyze how these activities affect firm performance using U.S biotechnology firm data. We found that Manufacturing/Marketing/Distribution Agreements increased firm performance in short-run. Also, collaboration with pharmaceutical and biotechnology firms had a positive effect on firm performance, too. However, collaboration with public institutes or universities had a negative effect on firm performance in short run, which implies its collaboration would be mainly focused on research in pure science area. These empirical results provide two policy implications. First, social network strategy should be encouraged in the Korean biotechnology industry. Secondly, governments should consider developing polices that support collaboration of biotechnology with public institutes or universities, to promote technological innovation.

Organization is increasing the authorizing process to use public certificate and bio information. Certificate, has evolved to be able to parallel distributes the bio authentication and portable bio-authentication device. Authentication using an individual's PC and smart devices continue to generalize, while convenience for authentication is increased by comparison Study on cooperation with the security at the network level's a weak situation. If ask authentication method through the cooperation of the public certificate and bio information work with current network access control, there is a possibility to develop a more powerful security policy. by cooperation weaknesses against vulnerable personal authentication techniques on security token in a reliable and secure personal authentication techniques, such as bio-recognition, Bio Information for identification and to prevent exposing a methodology suggest to validate whether or not to carry out in this paper. In addition, organize the scenario that can work with the 802.1x network authentication method, and presented a proposal aimed at realization.
