The current advancement of mobile devices enables users to collect a sequence of user positions by use of the positioning technology and thus the related research regarding positioning or location information are quite arising. An individual mobility model based on positioning data and time data are already established while group mobility model is not done yet. In this research, group mobility model, an extension of individual mobility model, and the process of establishment of group mobility model will be studied. Based on the previous research of group mobility model from two individual mobility model, a group mobility model with more than two individual model has been established and the transition pattern of the model is represented by Markov chain. In consideration of real application, the computing time to establish group mobility mode from huge positioning data has been drastically improved by use of GPGPU comparing to the use of traditional multicore systems.

In order to estimate the confidence level of the velocity distribution shown in a velocity image reconstructed from a travel-time tomography, the ray coverage and the inversion characteristics of the system matrix were investigated. The targets of the analysis is the first arrival travel-time, the raypath information, and the resulting velocity model. The ray coverage, degree of ray and model coupling, was estimated by the number of rays and total ray length in a velocity grid, and information regarding the resolution and uncertainties involved in the reconstructed velocity model was derived from the results of the SVD analysis of the system matrix that relates the data space (first arrival travel times) to the model space (velocity distribution in tomogram).

This paper proposes a reusable test case extraction technique for modified MATLAB Simulink/Stateflow (SL/SF) model. Creating test cases for complicated SL/SF model like ECU(Electrical Control Unit) of automotive, requires a lot of time and effort. An intuitive way to reduce to create new test cases whenever the model changes, is to reuse some test cases which have been generated for the original model. In this paper, we propose a method to define reusable test cases in SL/SF after defining model behavior and judging model equality by test cases. The proposed technique is evaluated using a commercial automotive controller model.

The mobile phone is the most private device for mobile communication. The goal of this paper is to present function relation model of the individualization and to analyze the task in the model by function pattern and function relation model in mobile phone. Function, activity, activity flow, intent of the activity, function group and influence between function and function group are used to present the function relation model which illustrates the relationship of the function in product. And this model drew up the function relation model for mobile phone. The function relation model for mobile phone based on the function pattern by the newest 3 phone's over 320 functions and 21 function groups. Last, to rearrange the function relation model to center on the individualization, the internal/ external memory to save and use the information for individualization function is placed to middle of the model. The main tasks of the model are storing, inquiry and interlock. The important methods to reinforce the individualization function are to develop the tasks which are the relations between the functions.

This study aims to derive the statistical models for the estimation of the required specifications of a rock TBM as well as for its cutterhead design suitable for a given rock mass condition. From a series of multi-variate regression analysis of 871 TBM driving data and 51 linear rock cutting test results, the optimum models were newly proposed to consider a variety of rock properties and mechanical cutting conditions. When the derived models were applied to two domestic shield tunnels, their predictions of cutter penetration depth, cutter acting forces and cutter spacing were very close to real TBM driving data, showing their high applicability.

Recently, interesting of U-city with ubiquitous computing technologies has increased and u-city services can improve people's quality of life. Among the u-city services, traffice service is actively developed in our lives. In this paper, we propose the business model and business model process in u-car tracking service. To propose the research purpose, we examined the prior business model and investigated u-car tracking information. And also, we draw scenario and used it to identify business model. To efficiently understand proposed business model, we built business model process of u-car tracking service. The results of study, we proposed business model and business model process with stakeholder, benefiter and value model. This study concludes with implications of the study results as well as limitations and future research directions.

최근 인터넷 쇼핑몰에서 고객의 충성도에 관한 연구가 다양하게 이루어지고 있다. 또한 쇼핑몰 사용자의 경험적인 측면의 중요성이 제기되면서 많은 연구에서 이를 플로우란 개념으로 설명하고 있다. 본 연구는 인터넷 쇼핑몰에서의 최적 경험으로서의 플로우와 그 동안 인터넷 쇼핑몰 관련 연구에서 고객 충성도와의 긍정적 관계에 대해 논의가 있어온, 신뢰와 만족과의 관계를 공분산 구조 분석을 통해 경쟁 모델화 하여 비교함으로써 우수 모델을 도출하였다. 그 결과 플로우와 신뢰, 만족, 충성도간의 관계를 모두 고려한 포화모델이 우수한 모델로 도출되었다.

유비쿼터스 컴퓨팅은 네트워크로 상호연결된 프로세서로 구성되며, 하나 이상의 컴퓨터로 이뤄진다. 하지만 기존 보안 솔류션은 존속성에 대한 명확한 정의가 결여되어 있어 본 논문에서는 유비쿼터스 컴퓨팅 시스템을 위한 존속성을 기반으로 하여 시스템의 보안 정도를 정량적으로 측정할 수 있는 기법을 제안한다. 존속성을 모델링하기 위한 논리적 첫 단계가 요구사항 도출이므로 먼저 공격 유형 모델을 도출하고 실제공격 사례 중 Code-Red 웜 공격을 공격 유형 모델과 존속성 모델을 통해 분석하였다.
