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 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...

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.

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...

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.
