DNA chips are used for experiments on genes and provide useful information that could be further analyzed. Using the data extracted from the DNA chips to find useful patterns or information has become a very important issue. In this paper, we explain the application developed for classifying DNA chip data using a classification method based on the Particle Swarm Optimization (PSO) algorithm. Considering that DNA chip data is extremely large and has a fuzzy characteristic, an algorithm that imitates the ecosystem such as the PSO algorithm is suitable to be used for analyzing such data. The application enables researchers to customize the PSO algorithm parameters and see detail results of the classification rules.

무선 네트워크의 대역폭 향상 및 무선 단말기의 컨버전스화로 인해 다양한 데이터 서비스가 기능해 지고 있으며 특히 대기 화면은 이러한 모바일 서비스의 Entry Poin 로써 서비스 제공자 및 사용자의 요구에 의해 좀 더 많은 Customize 가 가능한 공간으로 점차 진화하고 있다. 이에 따라 국 내외 이동 통신사와 단말 제조사들은 각기 개성 있는 대기화면 모바일 위젯 서비스를 출시하고 있으나 대부분의 경우 서비스 제공자의 관점에서 기획되어 아직까지는 사용자들의 높은 호응을 받고 있지 않다고 판단된다. 본 연구에서는 사용자의 Latent 한 Core Needs 를 파악하기 위해 Ethnographic Observation 조사 기법과 Online Survey 및 FGI 를 병행하여 사용자가 일상생활에서 가치를 두는 시사점을 발굴하고 이를 통해 모바일 위젯 서비스를 기획/개발하는데 반영할 수 있는 UI Feature 들을 도출하였다.

A standard framework of CFD(Computational Fluid dynamics) analysis for railway system has been developed to evaluate the overall aerodynamic performance of railway system and has been adopted to numerical simulation of the pressure field around KTX train. The framework is composed of standard aerodynamic model and standard aerodynamic performance to customize the general CFD solution process reflecting the characteristics of railway system such as various operation mode and performance factors. The results show that the standard framework of CFD analysis for railway system can provide objectivity and consistency to the CFD analysis for railway system and the pressure field around KTX train has been successively solved.

The purpose of this study is to identify issues for an effective safety culture assessment by conducting a case study of an electronics manufacturing plant in Korea. Cooper's safety culture model was used as the assessment method, and Fleming and Hudson's safety culture maturity models were applied as assessment criteria. The results of the safety culture assessment showed that there needs to be a design optimized for study purposes. For example, the correlation between the questionnaire survey and in-depth interview needs to be analyzed. The result of the behavior monitoring should show the relationships with other dimensions. A safety culture maturity model has to be developed to customize the study factors and questions.

As a result of the policy for enforcing the information technology led by government and the effort of companies to get over economic crisis through the reformation of business process, the ERP market is being active. However, because imported ERP products that are supplied currently are designed for standard and rationality, they have a limit to support custom processes of domestic companies in South Korea. On the contrary, ERP products by domestic companies in South Korea are unable to support a consistent methodology of constructing ERP system. This is main reason why much time and costs are consumed than that of an original plan. To succeed in ERP construction, the purpose of ERP setup must be defined. To accomplish this end, it is required to analysis business process completely and to make a plan in detail. For ERP providers, they must support a characterized ERP construction methodology and lower the construction cost by improving an ERP package easy to customize[5].

Active networks aim to provide a software framework that enables active network applications to customize the processing their communications. Active security component architecture focuses on the support of reuse system by active security component. The architecture is standard layer to acquire, understand, and assemble component, and it has to support a guideline for component identification, search and customization. In this paper we present the active security architecture as a standard model of discrete active network solution, and we propose the method for component classification and specification.

In this paper, we design and implement a distributed web-storage and a group office system based on the distributed web-storage. It is easier to customize the proposed group office according to user's demands than existing web-based applications. Our proposed web-storage is distributed system which consists of multiple storage servers. The web-storage provides storage with considering the user's location so as to provide fast storage service.

Many companies are investing in the development of the PDM(Prodct Data Management) system to improve the productivities of manufacturing since people believe that PDM technology can give a new solution from planning to development. As the requirements of PDM grows, so many industries sped their own budget on developing common requirements and functionalities. In this paper, we describe the framework for a PDM application to promote reuse in a PDM system development area. However, developing the framework is not easy. In this paper, the current state and results of our development are described: 1) the phases of developing our framework, 2) abstruction strategies, 3) programing model based on repository. Although frameworks improve software reuse, frameworks are so large and complex that application developers require to understand framework in order to customize the framework. To support the customization of framework, development environment is developed, also.

In this paper, we propose a common simulation model that can be reused for different performance evaluations of networked virtual environments. To this end, we analyzed the common features of NVEs, in which multiple regions compose a shared space, and where a user has his/her own interest area. Communication architecture can be client-server or peer-server models. In usual simulations, users move around the world while the number of users varies with the system. Our model provides various simulation parameters to customize the region configuration and user movement pattern. Furthermore, our model introduces a way to mimic a lot of users in a minimal experiment environment. The proposed model is integrated with our network framework, which supports various scalability approaches. We specifically applied our model to the interest management and load distribution schemes to evaluate communication overhead. With the proposed simulation model, a new simulation can be easily designed in a large-scale environment.

Recently, As smart phone offers rather superior functionality and interface than normal phone, the number of user increase rapidly. for the convenience of user, there are so many case of customize the system. Simultaneously a number of smart phones which vulnerable to security increase Exponentially. The number of malware which targets smartphone increases Annually, namely Threats have intensified. In this thesis, we suggest the Techniques and countermeasures of the vulnerability which targets aviation communication system by Smart-phone RF module with frequency modulation.
