The Adoption of programming education has become a global trend. In Japan, the Japan Revitalization Strategy 2016, announced by the Headquarters for Japan's Economic Revitalization in 2016, set forth the aim of making programming education compulsory in primary and secondary education. The purpose of this is to cultivate basic logical thinking skil...

Japan in recent years has seen a succession of cases of accounting improprieties. For example, a study by Tokyo Shoko Research shows that 57 publicly traded companies disclosed improper accounting or bookkeeping during 2016 (January-December), reflecting a rapid increase of 2.2 times from the 25 companies that did so in 2008. The increase in such c...

In this paper, we deal with three-dimensional computational model, k-neighborhood template A-type two-dimensional bounded cellular acceptor on three-dimensional tapes, and discuss some basic properties. This model consists of a pair of a converter and a configuration-reader. The former converts the given three-dimensional tape to
two-dimensional c...

The purpose of this paper is an analysis of survival in the Japanese information service industry. Information service firms are generally classified into two typical patterns. One is the group of independent firms such as software vendors, and the other is the group of non-independent such as subsidiaries established by spinning off and so on. We...

This paper investigates the factors that influence the motives of make-or-buy decisions on information systems from the viewpoints of Transaction cost economics (TCE) and the resource-based view (RBV). Using our original questionnaire survey data carried out in 2007 targeting Japanese firms, we analyze the relationships between the recognition rela...

In line with the global trend toward enhancing education on computer programming, Japan has begun to consider making programming a required subject at the elementary-school level. While traditionally some programming education has been conducted starting at the level of secondary education, this policy would introduce it as a required subject at an...

In this paper, we investigate multi-dimensional computational model, k-neighborhood template A-type three-dimensional bounded cellular acceptor on four-dimensional tapes, and discuss some basic properties. This model consists of a pair of a converter and a configuration-reader. The former converts the given four-dimensional tape to three-dimensiona...

This paper deals with the study of four-dimensional automata. Recently, due to the advances in many application areas such as dynamic image processing, computer animation, augmented reality (AR), and so on, it is useful for analyzing computation of four-dimensional information processing (three-dimensional pattern processing with time axis) to expl...

We have proposed a new method of advancing from CS Unplugged through the new process of CS Plugged to full-fledged computer programming languages, as a means of deepening understanding in computer programming education. We also have proposed a new Five-Step Method consisting of the following steps: Step 1, A CS Unplugged activity; Step 2, A CS Plug...

The course we teach has about 40 students per class, aged 16 through 17 years. Since the students' major field of study is Management Information, they need to learn programming techniques. However, the results of the survey described below show that not a few students consider themselves to have insufficient understanding of programming or think t...

Cellular automata were investigated not only in the viewpoint of formal language theory, but also in the viewpoint of pattern recognition. Cellular automata can be classified into some types. A systolic pyramid automata is also one parallel model of various cellular automata. A homogeneous systolic pyramid automaton with n-dimensional layers (n-HSP...

Although two major Japanese manufacturers, Toyota and Mazda, compete in the automotive market, their corporate performance, respectively, is different because the internal resources and the way they coordinate interrelationships among their network partners is known to be divergent. Both these two companies have their own collaborating organization...

The study of four-dimensional automata as the computational model of four-dimensional pattern processing has been meaningful. However, it is conjectured that the three-dimensional pattern processing has its our difficulties not arising in two-or three-dimensional case. One of these difficulties occurs in recognizing topological properties of four-d...

In theoretical computer science, the Turing machine was introduced as a simple mathematical model of computers in 1936, and has played a number of important roles in understanding and exploiting basic concepts and mechanisms in computing and information processing. After that, the development of the processing of pictorial information by computer w...

This paper proposes and empirically tests a model of the relationship between green supply chain management (GSCM) practices and corporate performance. Based on a literature review, we identified five determinants, namely, environmental commitment, supplier collaboration, supplier assessment, information sharing among suppliers, and business proces...

Cloud computing services have not been yet deployed widely by the SMEs in Japan. Due to its many advantages, special skills and support techniques for the SMEs need to be developed in order to implement cloud computing services. A research of the relevant literature reveals that virtually no published academic research has focused on the rational r...

Recently, due to the advance in dynamic image processing, computer animation, augmented reality (AR), and so forth, it has become increasingly apparent that the study of four-dimensional pattern processing (three-dimensional pattern processing with time axis) should be very important. Thus, the study of four-dimensional automata as the computationa...

M. Blum and C. Hewitt first proposed two-dimensional automata as a computational model of two-dimensional pattern processing in 1967, and investigated their pattern recognition abilities. Since then, many researchers in this field have investigated many properties of automata on a two- or three-dimensional tape. However, the question of whether pro...

Informally, the parallel Turing machine (PTM) proposed by Wiedermann is a set of identical usual sequential Turing machines
(STMs) cooperating on two common tapes: a storage tape and an input tape. Moreover, STMs which represent the individual processors
of a parallel computer can multiply themselves in the course of computation. On the other hand,...

A multi-marker automaton is a finite automaton which keeps marks as pebbles in the finite control, and cannot rewrite any input symbols but can make marks on its input with the restriction that only a bounded number of these marks can exist at any given time. An improvement of picture recognizability of the finite automaton is the reason why the mu...

A characteristic feature of the outsourcing of information systems (IS) in Japan is the use of quasi-outsourcing primarily by large-scale firms. In most such cases, an IS subsidiary is established by spinning off the firm's own information systems department. However, in recent years, there have been many firms which strengthen capital alliances be...
