Focusing on the similarity between the process of drawing and the semiotic triangle, elucidating their relationship with the sub-abilities that constitute the abstraction ability, it devises a drawing education programme that focuses on 'observing' rather than 'drawing'. The drawing education programme formulated is implemented on 177 students, and the result is determined using tests that enable objective evaluation to prove the effectiveness of the program in helping students acquire the 'three sub-abilities' that constitute the abstraction ability.The educational programme proposed in this research, which focuses on the universality of the effects of learning drawing, as well as the quantitative criteria for evaluating it, will contribute to familiarize practical education in the field of art to the gener...

In system development process, a construction of Using System is developed into function of Object System, and then continued with development of construction of Object System. Construction can be represented by DEMO Construction Model and function can be represented by Business Model Canvas. To manipulate a function system, we need to define a specification or construction of that system. Therefore we need to be able to generate a construction from a function. This study attempts to create a linkage between Business Model Canvas and DEMO Construction Model as a construction design process. A methodology of generating DEMO Construction Model from Business Model Canvas is proposed. Case study of City Logistics is used to illustrate the proposed methodology. We found the correspondence between Business Model Canvas and DEMO Construction Model, and the proposed methodology proved to be able to create DEMO Construction Model from Business Model Canvas through step-by-step process.

The latter two concepts are redefined as the achievement of business objectives by the use of IT or digital technologies in a balanced scorecard approach. The concepts of 'Knowledge Creating Capabilities' and 'Balanced SECI' are leveraged. Balanced SECI (Riera, Senoo and Iijima, 2009) refers to the balance of the four knowledge creation processes from Nonaka and Takeuchi's SECI model (1995). This framework is applied to Japanese small and medium enterprises. A positive relationship between the achievement of business objectives by IT and the achievement using digital technologies was verified. On the other hand, although a relationship of 'Balanced SECI' with 'IT Business Value' or 'Digital Business Value' was not statistically significant; the observations showed that higher levels of 'Balanced SECI' were negatively related to the achievement of Financial, Customer and Business Processes types of business objectives and; positively related to Learning & Growth. Analysis from each SECI process confirmed such behaviour.

Formal Specification of DEMO Process Model and Its Submodel - Towards Algebra of DEMO Models

In general, a submodel is a part of a given model. An earlier work proposed how submodels of a given DEMO Construction Model (CM) can be attained by a set-theoretic formalization. However, it remains unclear how to expand the formalism to the notion of submodels of a given PM. Since the given PM should align with the corresponding CM, a submodel of the given PM should not only be a PM, but also conform to the corresponding submodel of the CM. These two independent constraints indicate the desired definition and formalization of submodels of PMs. The proposed approach is shown to be applicable to a common demonstration case. Through the formalization, this paper shows the closure, commutativity, and associativity of the merge operation over submodels of a given PM. Moreover, it is found that the consistency between CMs a...

Yet, there are un-pioneered challenges for the people who lead and manage smart tourism projects and realize its value in smart tourism (we call them as ‘Smart tourism initiatives’), such as coordinating of tourism complexity, planning and sharing tourism strategy, sustaining tourism projects and innovation. In light of these challenges, the overall objective of this work is to design a holistic capability maturity model for smart tourism governance enabling sustainable tourism innovations via tackling the challenges above. The Dynamic capability theory was adopted as a theoretical lens, and the Design science research methodology was introduced to develop a new capability maturity governance model as a design artifact. And We could synthesize findings from iterations of the design research cycle based on the IT Capability Maturity Model. The results of the study propose a potential capability maturity mod...

However, most attempts have yet to be realized completely. The lack of theoretical discussion and modelling in tourism governance is a major contributing factor. This paper empirically explores the potential of systematic governance in achieving sustainable competitive advantage in smart tourism. We conducted a case study via qualitative interviews with tourism initiators from one of the leading tourism cities in Tokyo, Japan. In the theory building process, we adopted absorptive capacity as the theoretical foundation, and we could synthesize the outcome of our analysis into the proposed framework-Smart tourism dynamic capability governance Model. The model demonstrates how a city could dynamically manage their tourism resource and capabilities in their ecosystem toward sustainable tourism prosperity. Throughout this study, we contribute to the body of knowledge by introducing a successful tourism governance approach to compete with tourism resource rich cities.

Present trends of business modeling methodologies are to include the social context of an organization. Although various methodologies have been developed specially for the business process field and have a social context, it is not in terms of goals and customers, but processes, activities, and tasks. We describe our stance on business process modeling, based on the viewpoint of goal and customer. First, we formalize a goal-oriented business process model and its evaluation mechanism. Second, we propose a methodology of business process modeling, which starts from perceiving and describing interactions between organization and customer from the customer's viewpoint.

This is due to the complexity of the related information. Therefore, an abstract model of the enterprise is needed to focus on people and their needs before developing any information system. To respond to this need, new modeling methodologies that focus on modeling the enterprise as a social system have got a wide acceptance. DEMO and i* are an example of these modeling methodologies. They focus on modeling the people and the interaction between them. Although DEMO is a based on strong theories, it is not used much as i* in requirement engineering. Therefore, this research compares these two modeling methodology in identifying the functional requirements for developing information system. The comparison is to highlight the strong and the weak part of both modelings. Moreover, this research draws guidelines for improving both methodologies in modeling enterprise as a prior step in developing information system. As a result, the concept of modeling the interaction between DEMO and i* is different. DEMO is more formal inmodeling the interaction rather than i*. Moreover, DEMO models both the structure and the behavior through its different diagrams. But i* does not capture the behavior. In contrast, i* allows to model the non-functional requirements, too. Sometimes it is useful to analysis them during the first stages of requirements analysis.

Integrating shared location delivery systems with home delivery has been a new trend in tackling last mile delivery challenges. This paper studies the Capacitated Vehicle Routing Problem with Delivery Options (CVRPDO). In this problem, customers can choose between picking up their requests from a shared location or receiving them at their homes within a preferred time window. The problem is formulated mathematically to minimize the total delivery costs considering the customers’ preferences. Results include comparisons between delivery costs in the standard Capacitated Vehicle Routing Problem (CVRP) and those in the CVRPDO. Results demonstrate that the CVRPDO outperforms the CVRP by a considerable margin for varied-size instances providing a justification for substantial investment in establishing shared locations for deli...

To create a new system, we can perform manipulation of existing systems. A construction system can be decomposed into several subsystems, and those subsystems can be merged into another construction system. Construction of an enterprise can be represented by DEMO (Design & Engineering Methodology for Organizations), specifically DEMO Construction Model. This research attempts to demonstrate the process of construction model generation using DEMO, and also develops the criteria for submodels and merged models. This article applies a case study of telecommunication industry in Indonesia. By using this framework, one can gather several enterprise models and model them as construction models, generate submodels and create a pool of submodels, merge them to generate a new construction model.

Commonly, mobile commerce is considered to be another new application of existing web-based e-commerce onto wireless networks, but as an independent business area, mobile commerce has its own advantages and challenges as opposed to traditional e-commerce applications. This paper focuses on exploring the unique features of mobile commerce as compared with traditional e-commerce. Also, there are still some limitations arisen in m-commerce in contrast to web-based e-commerce. Finally, current state of mobile commerce in Japan is presented in brief, with an introduction of several cases involving mobile commerce applications in today's marketplace.

To increase the adoption of home care, it is necessary to create a mutual understanding of the current home care system, and to improve the cooperation of stakeholders. From the process perspective, after analysing 6 related organizations in Central Finland, this study created a general model of the current home care system in Central Finland by using DEMO Construction Model, and pointed out several problems in its real implementation. This study demonstrates that DEMO is applicable to the examination of essential processes in health care systems and can offer suggestions for improvement.
