오늘날 데이터를 표현하고 교환하는 표준 언어로 XML을 사용하고 있다. XML의 개념적 모델을 정의하기 위해서는 XML이 가지는 다양한 요소들을 다이어그램으로 표현하는 표현 규칙과 생성된 다이어그램을 논리적 모델인 XML로 변환하는 변환 알고리즘을 정의해야 한다. 본 논문은 XML의 개념적 모델로부터 논리적 모델을 생성하기 위한 변환 기법을 제안한다. 본 논문에서 사용하는 개념적 모델로는 CMXML을 이용하고, 논리적 모델로 XML 스키마를 생성한다. 이를 위해 다이어그램으로 표현되는 CMXML을 정의하고, 이 다이어그램으로부터 XML 스키마를 생성하기 위한 자료구조를 정의하고 생성규칙을 정의하고, 변환 알고리즘을 제시한다.

일반적으로 시뮬레이션 프로젝트는 목적에 부합되는 수준에서 연구 대상 시스템과 유사하게 작동되는 모델을 개발해야 하기 때문에 시간과 비용이 많이 소요된다. 따라서 적절한 개념 모델 설계와 이를 바탕으로 시뮬레이션 모델을 자동 생성하여 모델 개발 과정의 시행착오를 최소화함으로써 모델링 시간을 단축하기 위한 연구가 요구되고 있다. 본 논문에서는 실무에서 많이 사용되고 있는 Microsoft Excel과 Visio를 활용하여 개념 모델을 개발하고 이를 Arena 모델로 자동으로 변환하는 툴을 제안하였다. 예제를 이용하여 본 논문의 모델 자동 생성 툴의 효용성을 보였다.

Objective: This study presents the conceptual framework and the conceptual model to account for user experience by expanding the existing concepts of usability, in particular considering the user-interface environment in digital convergence. Background: To better understand a variety of users interacting with a converged product based on digital technologies, there seems to be a limit to consider the existing concepts of usability. All possible aspects of user's interaction with a product in a context of use need to be taken into consideration. Method: This study identifies the concept of user experience through a comprehensive literature review. Results: First, this study reviews the existing concepts of usability and user experience. And then this study describes four main components in the conceptual framework of user experience: user's internal states, user's external states, a product, and various outcomes, each of which encompasses distinct sub-components. The conceptual model of user experience accounts for how user's internal states change over time and for how different sub-components affect actual behavior of use. Conclusion: It is expected that these user experience concepts can be used in basic resources to better understand different behavioral characteristics of users and to better design interactive products in converged digital environments.

A conceptual system dynamics model is developed to represent the dynamic mechanism between the number of hepatitis B virus and the defense system of the body. The simulation results shows that the model behaves within the reasonable ranges. The developed conceptual model is a first attempt to quantify the dynamic mechanisms of the hepatitis B virus, where only feedback structures are considered without bio-organism data. The next step would be to incorporate the model with bio-organism theory and to carry out case studies to identify personal characteristics. Since the current model is a conceptual model where quantitative results are not based on the sound background, the usage is limited only within the qualitative basis. It could be a effective educational tool for the patients. It also shows what-to-do lists in order to be used for forecast purposes.

This paper dealt with developing conceptual model for making public policy on consumer product safety. The matters of consumer safety, public health and environmental protection are essential parts of making policy for consumer products. Moreover, policy authority should consider all measures based on consumer safety. In the process making regulations, policy authority has to have some methods to prevent errors on treating eligible persons as persons disqualified under uncertainty decision making of public policy. To recognize and ensure fairness on public policy, policy authority needs to establish basic policy making and fundamental concepts. Therefore, we developed conceptual model for consumer products safety, CPSPcon in this paper. The conceptual model is one part of SSM(Soft System Methodology) and can support specific policy target. The CPSPcon model can assist in evaluation of responses to an adapting or considering model.

This paper describes the intent of learners to acquire university education, the basis for selecting study courses, the means to assess the quality of higher education, what the challenges faced by the learners are, as well as suggestions for improvement. The design and system thinking approach has been adapted to address the well-being issues of B40 young people in Bangladesh, through understanding their need, followed by building conceptual business models using modeling tools, i.e., Business Model Canvas (BMC) and Value Proposition Canvas (VPC) model. The main objective of this paper is to investigate the contribution and the role of a Malaysian University to solve problems of quality of higher education in Bangladesh and what initiatives should be taken to overcome this problem. This paper offers a validated conceptual Malaysian University of the Future (UotF) business model with the focus on international community engagement programs to help Bangladeshi students to acquire knowledge, abilities, skills, and values toward developing a harmonious and sustainable society. The contribution of this paper is the presentation of a conceptual, validated business model in both BMC and VPC formats. This conceptual business model can further be applied to civic engagement operations by other universities.

도로 및 철도 신설에 따른 터널 굴착으로 지하수가 유출될 경우 지하수 자원 고갈, 농업용수 및 생활용수 부족 및 지표수 유량의 변화 등이 예상된다. 이러한 터널 굴착에 따른 지하수계의 변화를 예측하기 위해 3차원 유한차분 모형인 MODFLOW가 가장 널리 이용되고 있는 추세이다. 지하수 유동 모델링 실무에서 개념모델의 설정은 가장 중요한 요소 중 하나이다. 개념모델을 너무 단순화하였을 경우 모델링 결과로부터 필요한 정보를 얻어낼 수 없는 상황이 발생할 수 있고, 혹은 너무 복잡하게 개념모델을 설정하였을 경우 필요한 현장 자료가 부족할 수 있으며, 수집이 되었더라도 모델을 구동하는데 과다하게 많은 시간과 자원이 소요될 수 있다. 본 연구에서는 터널 굴착에 관한 지하수 모델링을 수행할 경우 개념 모델 설정에 따른 모델링 결과를 비교하여 현실에 보다 적합하고 효율적인 개념모델 구성에 대해 고찰하였다.

In this paper, we develop a new conceptual framework for finding new business opportunities in the cloud computing environment. We propose a service model framework for cloud computing business. In the service concept of the proposed business model, we categorize customer needs and service offering value, while we analyze customer behavior for developing revenue model. In addition, we analyze cloud computing market drivers for finding an evolution path of the proposed business model. Finally, we develop cloud computing business strategies for Korean IT service industry.
