Used detached houses in Japan become valueless in 20-25 years since construction. This makes it difficult for the owners to have an incentive to maintain their own buildings. Although both public and private sectors have tried to lengthen the value of buildings, no decisive measures have been found yet. We consider a game of two buyers of used detached houses of the same quality. We regard evaluation of the economic life of the building at the time of purchase as a strategy and the capital gain at the time of sale as a payoff, and model the relation between the time period until buildings are sold and the gain. We study effective policies for lengthening the value of buildings.
The development which is increasingly is expected of these days and the fitness industry health-consciousness accelerates. The enterprise the sales raise more than 5 years before is most indeed by a major overall gym operation enterprise, but achievement is piling up at a part enterprise. So major number company is chosen and a management strategy of an enterprise and the feature are analyzed based on financial data and all kinds' opening to the public information.
It is necessary to be allowed to work remotely due to workstyle diversification and women's social advancement. It is allowed to work from home in some companies. And there are variety of application software for online conference. It is therefore going to drive new environment for remote-work. On the other hand, it is said that there are less small talks in online than off-line conference in which all participants get together in one place. It seems to be disconnection between Socialization and Externalization. It is hence said that online conference is inferior to off-line conference in terms of knowledge creation force. We are, in this paper, aiming at making sure obstructive factor and its countermeasure for knowledge creation in online conference, and create research strategy.
In recent years, a representative service is a robot advisor as a case where FinTech is paying attention in the securities industry. A robot advisor is a service that proposes an optimal portfolio and supports investment according to the person's intention according to a program when individual investors answer a few questions. In this research, we compare the performances of multiple robot advisers and how consciousness to investment changes when people without investment experience use robot advisors.
Why does Bitcoin attracts attention now? That's because using systems such as a block chain makes Bitcoin higher reliable. The number of altcoins and projects called Bitcoin 2.0 are now increasing as Bitcoin's system is easy to use and spreading its high reliability. We could have great hope for possibilities of Bitcoin 2.0 particularly some kind of bitcoins like Counterparty that uses Bitcoin as new ways and others like Ethereum that uses a unique block chain. In this report we consider reliability of Bitcoin and possibility of application to Bitcoin 2.0.
A shift of a social system may possibly be prevented by conflicts among participants with respect to cost allocations associated with the shift, even if the new system is much more beneficial than the present system. For instance, a shift of the pension system in Japan from pay-as-you-go system to funded system is not achieved partly because there is supposed to be a cost allocation conflict among generations. In this study, a cost allocation conflict associated with a social system shift is modeled as a normal-form game, and best responses of each player and equilibria are investigated. Conditions under which whole cost is allocated and the social system shift is achieved are examined.
In recent years, the market of P2P Lending is expanding. In a certain company in japan, amount of loan contracts in October 2016 is 1.6 times as much as the same month of the previous year and it is growing now. P2P Lending is the system which connect investors to borrowing people and combine on an auction form and so on. It can be said that P2P Lending is a kind of Cloud Funding, but it is different that investors don't want a repayment. In addition, matching platform conducts credit administration. In this paper, we compare and discuss business models of P2P Lending companies in Japan.
How to model and forecast the volatility, which is the risk of financial assets, is one of the important issues in the financial institution management. Therefore, many prior studies have proposed various models reflected real financial markets. In this study, we attempt to apply the Recurrent Neural Network architecture (Simple RNN, LSTM, GRU) to modeling the volatility clustering and forecasting the future volatility. Using the Recurrent Neural Network architecture, there is a possibility that we could automatically capture structures of the conditional volatility, as ever we have designed manually. In comparison with the GARCH (1,1) model, we analysis a predictability for the conditional volatility.
Recently, the new settlement services like Applepay and Square have appeared. Although the movement of "FinTech" started in Japan, this movement is still in the first step to grow up. For examples, in China, the services which is the frontier in the world have expanded like "Alipay" which is the settlement service ZHIFUBAO provides and "Tencent" which provides a lot of games and social networking services. It is widely expected that Japanese settlement services will improve more and more in the future. In this research, we consider the present condition of "FinTech" and the potential to develop in Japan with comparing with Chinese ones.
This study investigates the influence of organizational slack, that is, surplus resources, and licensing-out of firms in the chemical industry on R&D capability. Organizational slack consists of absorbed slack measured by excessive cost, unabsorbed slack measured by excessive current assets, and potential slack measured by borrowing capacity. This study uses the panel data of firms in the chemical industry for?statistical?analysis. Results indicate that organizational slack and licensing-out?increase the?R&D expenditure and licensing-out improves the R&D capability of firms. It indicates that the firm can invest the revenue earned from the technological-out in R&D expenditure. Furthermore, firms can focus their resources on new technology that is suitable for their business.
This study demonstrates the influence of patents on the formulation of firms' external network. The prior research indicates that patents are an index of a firm's research and development (R&D) capability for product innovation. We employ a network analysis using a panel data from the petrochemical industry. In addition, this research also employs a statistical analysis using the index from the network analysis and firm data. The result shows that high R&D capabilities'firm has the external organizational network of technology-in that has a characteristic of high knowledge diverseness and knowledge acquisition efficiency.
Critical elements in the process of predicting business failures are selection of financial indicators and construction of a forecast model. Many traditional methods implement these two tasks separately, and do not guarantee the optimality on the whole process. This study uses the AdaBoost algorithm so that these two processes can be realized within a single coherent framework. Setting financial ratios generated from arbitrary two items in the time-series financial data as candidates of indicators, our proposed method selects the effective financial ratios and derives the discrimination function which can predict companies going bankrupt in a few years. Experimental results show that our method can distinguish failed firms from continuing ones with higher accuracy by using the proposed temporal financial ratios.
To evaluate enterprises,it is important to consider not only enterprise financial states but also enterprise strategies or those changes. In this article, we propose a method which extract the strategy words with differences among enterprises and changes in time sequence, based upon the stratified N-Gram method which is able to extract coined and proper words that are difficult to extract by morphological analysis. Proposed method supposes three appearance patterns of important strategy words as follows: (1) domain trend: spread to many enterprises in domain, (2) enterprise unique: appear in only one enterprise, (3) period specific: appear for a specific period. Then it extracts the strategic words with differences and changes, which fit any of three appearance patterns.
In dawning (1999 - 2002) of online securities trading service business, Matsui Securities Co., Ltd. had been having great advantages against other companies. After 2006, however, those advantages changed due to growth of other companies. In this article, we develop a dynamic model which are able to explain the causes of advantage changes and impacts which are affected by them. We developed the simulation model, by using systems dynamics methodology, which are able to demonstrate the impacts with considering three viewpoints as follows: (1) in two customer segments which have different dealing policy, (2) within the changes on business environment (fluctuations of deals volume as investment boom), (3) management policy (choice and focus on customer segment) each company took.
Recently, data mining methodologies, which computationally extract valuable information from huge data, have been applied to various areas. In this article, we try to extract companies and periods, which are presumed that they had been under characteristic business conditions (e.g. unique management policy), by identifying financial indicators that show characteristic behavior against other competitors for any period. We propose a method, which extract characteristic triplets of financial indicator, company and period by three evaluation criteria such as uniqueness of wave shape, uniqueness of variation, and uniqueness of level, from financial data as time sequences. Then we report the extracted results by the proposed method.
In IT systems development businesses as labor-intensive industries, acquisition of human resources is essential. It is difficult to adjust amount of human resources for ordered works in tempestuous change (e.g. Lehman Brothers' financial crisis) of demand, because of poor employment mobility in Japan. In this article, we develop a simulation model which can explain the financial impacts affected by human resources adjustment policies (emphasizing regular employments/subcontractors in shortage/excess). We developed the systems dynamics simulation model with considering four viewpoints as follows: (1) fluctuation of demand and amount of ordered works, (2) adjustment policies in shortage or excess, (3) decision on options adjusting human resources and amount of them according to those policies, (4) time lag of each option.
This paper discusses how the power of differentiation factors among the Subscribed Video On Demand (SVOD) servive changes before and after the consumer uses the web site. The paper points out that before using the SVOD both product factors and Internet-related factors, such as number of the contents, and good reviews, have power. But after using SVOD, the quality of the contents and usability factor have more power.
Mobile advertisements are growing rapidly with the spread of smartphones, but research on the latest mobile advertisements is limited. In this research, based on the technical acceptance model, we analyze the characteristics of service of mobile homepage, interactivity, mobility reliability, stability, security, information characteristics and characteristics of small businesses personal innovation, self-efficacy feeling, Analyze the relationship between immersion tendency and usefulness and ease of use and consider the influence of consumers on purchasing intention.
The asset management company enrolls in human resources who are required to have specialized knowledge related to mutual funds . I often hear that the personnel of the asset management company are motivated monetary compensation, while Knowledge workers with advanced skills are said to be motivated by factors other than monetary compensation. The category of knowledge workers is expanding and new knowledge on motivation is needed. Therefore, in this research, I investigated and analyzed as purpose to clarify the actual condition of how much human resources of the asset management company emphasizes monetary compensation and how motivated by other factors.
In order to promote the problem solving and structural reform of the Japanese economy, through the performance examination test system, the ability really needed in society, namely leadership, perseverance, creativity, breakthrough power, Identity, reliability, ambitious To realize capacity improvement, to stimulate human resources within the campus, within the company, the birth of venture companies, and the purpose of linking to the driving force of the Japanese economy
In this research, we conducted a survey of learning opportunities outside the workplace, and investigated and analyzed what learning methods people learning outside the workplace are doing. Working people learn a lot through work. Work experience promotes the development of working people and changes them like another person. However, Learning is not limited to only the workplace. Actually, many working people are studying independently outside the workplace. Studying sessions outside of the workplace that is a place of learning such as this are a private activity, so it is difficult to grasp the actual situation. Questionnaire survey and interview survey were conducted for those who are actually learning outside the workplace.
The purpose of this study is to explain how organizational contexts are created through phenomena that emerge from inter-personal relationships. I show the substantive theories that create a context within the organization, briefly described as follows: 1. Interpersonal relationships and behavior will be formed by the institutional norms of the organization. 2. A “person-to-person relationship" and its management will follow the institutional norms. 3. Management that forms “person-to-person relationships" will also form a “cooperational relationship" within the group. Qualitative aspects of the “co-operational relationship" will depend on “person-to-person relationships." 4. Organizational context will be formed by the behavior of the “co-operational relationship," which will be inherited by future generations and become institutionalized in the future organization.
Factors that security countermeasures for small and medium-sized enterprises do not advance are important.The top does not fully recognize the threat of advanced cyber attack and the magnitude of influence.Therefore, in order for the top to recognize the risk of cyber attack and to be able to judge whether or not countermeasure is necessary, consider the way to notice the necessity.We will also be able to proceed with the introduction and coping of CSIRT etc. in small and medium-sized enterprises. As an approach to this we try to consider risk recognition and countermeasures.
IoT leverage is out proceed, various smart world such as smart city, smart factory, smart infrastructure and smart grid has become a hot topic. However, there is the impression that has not been taken up about the common changes in those, because of the very large difference in each smart world. As a result, there may be a risk to trivialize or limit the influence of the undercurrent understanding of the changes that have occurred as a whole. From such awareness of the problem and the side of the new customer service obtained through the recent topic of sharing economy analysis, I try the common denominator search of changes that are expected in the future. Mention take a smart infrastructure as a specific example.
We are faced with a problem to make use of knowledge from experiences in tsunami-stricken area in the Great Tohoku Japan Earthquake. This study examines knowledge formalisation and its problem with implementation through a perspective of knowledge-based management. The aim of knowledge formalisation is to put knowledge in order, clarify knowledge and to simplify knowledge transfer. Formalising knowledge leads to contribution in various areas without reference to the spatial limit. This research deals with the problem of knowledge formalisation. Knowledge is not information. This paper examines how to formalise knowledge in consideration of traits of knowledge. Some principles for knowledge formalisation are made a study. In addition, difficulties will be pointed out about formalising tacit knowledge.
Vcn(g), one of the goal selection criteria in goal-oriented requirements engineering, has been proposed. Vcn(g) is a function defined on a preference matrix. In a preference matrix, only one stakeholder belonging to the same position must be set. However in fact, it is conceivable that there are stakeholders each of which has a different preference for a goal among them, even if they belongs to the same position. To resolve this problem, by three-dimensional extension of preference matrix, we extend preference matrix to make it possible to treat multiple stakeholders belonging to the same position, thereby, we define a novel goal selction criterion named Vcn3(g). Furthermore, in this paper, the result of an application experiment to a small goal graph of Vcn3(g) is described.
Artificial Intelligence drive "Smart city" more flexible and dynamic. Investment for corporate knowledgement and API economy will lead traditional companies as networked intelligent companies. Desiginig rule of such networked intelligent companies change the city more efficient and effective. Rules can change the function of "city", because such companies will change work-style and life-style by their knowldge power.We can design cities not only static things but also dyanamic "software deifined" life forms.
At the Tokai branch, the research activities which cooperated with the ITC Chubu are performed from last year. In this workshop, researchers and business men report the details of research from the view of each position, and make deepen an understanding about the subject of the management innovation of small companies through discussion with participants.
The innovation making in corporation is an organizational process. A wide perspective and creative thinking ability of the member and lively communication among members are required to stimulate innovation making. Cybozu, Inc, which has a high market share in groupware market, adopts its own SNS for internal communication. However its organizational dynamism comes from not from the SNS alone, rather from its tight linkage with the management philosophy and systems, corporate culture and business ecosystem.
Through practical learning such as field work and group study, to set academic goals and to improve problem-solving abilities and mutual communication skills are called Project Based Learning (PBL). Faculty of Business Administration in many universities practices PBL with third parties like private companies and public organizations. This report describes one year activity regarding the cooperation of Ishigaki-City, Okinawa and Sanno University, school of management for the promotion of the local industry. In these activities, the relationship made the students have more fun in learning and to stimulate their intellectual curiosity. Also, we found that the practical activity and lecture-style learning was not alternative but complementary to create practical and innovative solutions.
Today, many universities, in collaboration with industry, government and civil society, are working on “Civic Pride Development" (City of Yokohama Policy Bureau), a topic raised by the “Challenge! Open Governance 2016" program. While many collaborative projects and contests are being undertaken, most are based on fieldwork and hearings. Few are data driven. However, data utilization has recently become easier due to the increasing availability of open-source data, as exemplified by the Regional Economy Society Analysis System (RESAS). Still, many problems remain. This paper uses a PBL-based methodology to address the problems and possibilities of learning involving cooperation between industry, government, academia and civil society.
The essence of PBL is that it is learning by community form, and synchronization pressure etc. within the group and is expected to work effectively for learners. Academic-Social Cooperation based PBL is an attempt to introduce a "weak tie" by a third party to a learning community consisting of learners and teachers (tutors). However, academic-Social Cooperation based PBL appear companies and other entities become community members. Through research group, we conducted hearings, questionnaires, etc. on students, faculty members and on the social side who have PBL experience, and organized the expectations of mutual roles, expectations of PBL, etc. From there, it became clear that the need for "a strong learning community" is being constructed for weak ties to work.
The problems of the conventional style knowledge transfer class have become an important issue in school education. In this report, we describe what kind of learning can be expected for both sides from the experience gained from learning tasks through joint group work between primary school students and university students. A diverse group of learners of elementary school students familiar with group learning and university students who exceeded the target knowledge was created on the theme of social change in the postwar high growth period. The hypothesis that it is necessary to clarify and strengthen mutual roles was obtained for PBL with a diversity of learners.
When management is regarded as a system, discussions on numerous management are being developed. However, it should be recognized that the reality changes with changes in the times, and there is always a gap between the theory and the actual situation. The inability to maintain consistency between management ideals and reality causes various problems and decreases confidence as management. Based on the basic structure of management, we will try to develop logical and unified thinking of management based on the contents of management functions and actions.
Previous way of model businesses from static process models is no more effective nowadays, where enormous data like IoT or Bigdata is produced and should be properly handled. To solve the situation, new way of modeling business, which catches Business Events ( the business situations should be taken care of ) through data and present actions needed dynamically, is needed. Business Event Management enables us to model businesses from view point of Business Event and Action, and provides the way to handle businesses dynamically and quickly.
As part of the open data policy, the Japanese government has established and operated a data catalog site "Data.go.jp", and about 17 thousand data sets have been released. A function to send opinions and questions is provided to this site, and responses to them are also released. In this research, we conduct a case analysis on the "Opinion ・ Answer release corner" shown in "Data.go.jp". Through this analysis, we discuss the possibilities and challenges for the government to promote open data.
Japan started the issue of my number card in October, 2015. However, the spread of my number cards is largely late by system failure at the time of the card publication.If my number cards do not spread, the improvement of the convenience of the nation cannot be accomplished.The purpose of this study is to analyze the twitter data at key points in time using technique of the text mining.In addition, I performed it including analysis about the government public information using twitter.As a result of analysis, the effect of the public information was proved not to penetrate enough at this stage.
In this paper, we conducted a case study in the field of life science to propose a method to detect expected researchers by analyzing co-authorship networks from the academic paper database of Japan Science and Technology Agency (JST). We define the researchers with high centralities in the co-authorship networks as excellent researchers, then we propose a method to detect expected researchers by analyzing growth of the centralities in the course of time. In addition, we aim to clarify the characteristics of expected researchers by analyzing relationship between these researchers and their research fields and/or institutions they belong.
Agriculture is seen to promise a growth industry now in Japan with special concern to foreign free trade movements. Whereas in cities agronomy is seldom known also ones in remarkably progress. In everyday fresh use agrifood must be indispensably readied in mass, cheap and stable manners. Proceeding domestic local reduction clarifies metropolis efficiently fed by near Kanto farms. However Kanto not necessarily shows prospective system yet. I would try to research A prefecture case in Kanto in various media in charge.
Sales, which is the main objective of business activities, are realized through sales activities. Therefore, sales activities are regarded as one of the most important activities in business activities. In recent years, replacement of human work by artificial intelligence has attracted attention, but sales activities are regarded as one of the most difficult tasks to replace. For these reasons, it is meaningful to accumulate analysis based on academic approaches for sales activities. This research analyzes the text data answers of the questionnaire survey conducted to sales personnel. Open-ended questions asked salespersons' perception of the most important and the most difficult issues in conducting business activities. We will show the results of analyzing the answer by using text mining.
In the food supermarket industry, it begins to take a community-based strategy. However, consumer's recent purchasing by the diversification of the life style has been complicated. Therefore, it is difficult for the enterprise to take measures of goods in stock and the coupon distribution, etc. by thinking about the timing to come to a store and customer's needs. In the research of the past, characteristics of the region are not considered though the customer's segmentation was tried from the ID-POS data. Then, it was assumed to be a research purpose to propose the sales strategy technique for considering characteristics of the region by segmenting the customer in consideration of regional information in addition to the ID-POS data in this research.
In despite of using shared service, it is difficult to say that office workers work in an efficient manner. We conducted ethnography research on the relationship between shared service operators and their customers. As a result, we have found that it has five communication barriers from the view of business rules, knowledge, mutual understanding, psychology and physical characteristics. And then, we tried to introduce concierge service providing advice, connection and teaching roles, and have found the effect of the lowering of psychological barriers to be hard to approach and knowledge one to ask for an undefined work. We can get the opportunities to eliminate all of communication barriers with more strengthening the mutual relationship to increase reliability.
We clarified the following two points about the success factors in Japanese crowdfunding by analyzing the data of the Japanese crowdfunding platform and comparing it with the research in the U.S. Firstly, as common points between Japan and the U.S., it is confirmed that the increase of target amount and duration were negatively associated with success rate, and the increase of publicity were positively associated. It is suggested that similar tendencies may exist in regions other than Japan and the U.S. Secondly, as differences between Japan and the U.S., it cannot be said that videos were positively associated in Japan despite existing research that videos were positively associated in U.S. It was suggested that utilizing videos is necessary in Japan.
Many enterprises or countries are driving forward the 4th Industrial Revolution, based on IoT technologies. However, the Revolution is bringing changes not only to industrial world but also to private lives and further consumptive society. Moreover, the IoT technologies are bringing revolutionary changes to the cyber space being materialized with computing technologies, and also generate new business models. Therefore, it is discussed re-systematizing the business models.
Recently, there have been a growing number of communities which aim to establish a brand image as a “Bike-Friendly City". The branding strategy, however, varies depending on the target markets, such as tourists or local residents. This study focused on a branding strategy which targets cycle tourists, and discussed how to develop a cycle tourism information system. Therefore, in the draft, we will conduct research focusing on bicycle use for residents about the "bicycle city" that is used ambiguously. Specifically, we attempt to reconsider daily use of bicycles, try to clarify the "information on bicycles" needed by residents, and also consider the way local governments disseminate information on bicycles.

The newest BSC allowed us to align IT investments with the company strategy. On the other hand, we have the EA framework to design the entire enterprise information systems. Because EA should contribute the achievement of the company strategy, BSC and EA must be unified. In this report we present the unified management model according to 'Enterprise Architecture Maturity Stages'.
Social business is attracting attention to work by using the technique of business to social issues. To solving social issues by using ICT, it is expected to create new value and solutions. However, a method of used ICT in social business has not been established. Therefore, this study pays attention to changes in the business processes of the social business, and analyzed the success factor of the social business. As a social business used ICT, pick up the case of the Uchiko Fresh Park Karari which has been conducted in Uchiko Town, Ehime Prefecture. Through analysis using DEMO which is a kind of business modeling approach and interviews research, some characteristics of ICT in social business are clarified.
Accelerated technology development ebables us to realize decetralized netowok system such as SNS, Uber and block chain algorithm. These autonomous and decentaralized End to End platform system, where shring information is mutually apprecitaed, may cause chage participants' notion regarding so called sensitive infoamation, especailly privacy information. This presentation attempts to refer a possibility of change of trust architecture.
