The existence of mathematical objects was considered through diorism which was used in ancient Greece as conditions for the existence of the solution of the problem. Proposition I-22 of Euclid Elements has diorism for the existence of triangle. By discussing the diorism in Elements, ancient Greek mathematician proved the existence of defined object by postulates or theorems. Therefore, the existence of mathematical object is verifiability in the axiom system. From this perspective, construction is the main method to guarantee the existence in the Elements. Furthermore, we suggest some implications about the existence of mathematical objects in school mathematics.

A business model (BM) can be developed based on a business model framework (BMF) consisting of key components such as value proposition, customers, and resources. To systematically generate and analyze emerging BMs such as healthcare BM, an integration of diverse BMF components is needed. The present study is to establish a comprehensive BMF and evaluate its applicability to healthcare BMs. Based on a review of eight BMF studies, ten BMF components were identified and classified into five major components (value proposition, resources, organizing model, customers, and revenue model) and five minor components (technology, service platform, delivery, competitive strategy, and growth/exit) by analyses of frequency and functional importance. Lastly, the BMs of three emerging healthcare companies (WellDoc, Inc., CFW Shops, and Aravind Eye Care System) were analyzed and compared in terms of the proposed BMF components. The comprehensive BMF components presented in the study can be of help for developing new BMs and analyzing the strengths and weaknesses of BMs.

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.

Online consumer activities have increased considerably since the COVID-19 outbreak. For the products and services which have an impact on everyday life, online reviews and recommendations can play a significant role in consumer decision-making processes. Thus, to better serve their customers, online firms are required to build online-centric marketing strategies. Especially, it is essential to define core value of customers based on the online customer reviews and to propose these values to their customers. This study discovers specific perceived values of customers in regard to a certain product and service, using online customer reviews and proposes a customer value proposition methodology which enables online firms to develop more effective marketing strategies. In order to discover customers value, the methodology employs a text-mining technology, which combines a sentiment analysis and topic modeling. By the methodology, customer emotions and value factors can be more clearly defined. It is expected that online firms can better identify value elements of their respective customers, provide appropriate value propositions, and thus gain sustainable competitive advantage.

Success in Knowledge Management depends critically on the evaluation system that managers of an organization evaluate objectively performance of members of the organization. In particular, the differences in the standard of Performance evaluation used by managers in Governmental Institution or Agency of make an issue of the standardization of Performance evaluation. Therefore, in this paper we propose the alternative evaluation method, which minimizes the bias resulted from the different standards by measuring ranking of knowledge workers, instead of quantitative analysis, using Median Rank method in Reliability and verify our proposition using the analysis of examples.

In this paper, the neuro-fuzzy inferene system for the effective object recognition is studied. The proposed neuro-fuzzy inference system combines learning capability of neural network with inference process of fuzzy theory, and the system executes the fuzzy inference by neural network automatically. The proposed system consists of the antecedence neural network, the consequent neural network, and the fuzzy operational part, For dissolving the ambiguity of recognition due to input variance in the neuro-fuzzy inference system, the antecedence’s fuzzy proposition of the inference rules are automatically produced by error back propagation learining rule. Therefore, when the fuzzy inference is made, the shape of membership functions os adaptively modified according to the variation. The antecedence neural netwerk constructs a separated MNN(Model Classification Neural Network)and LNN(Line segment Classification Neural Networks)for dissolving the degradation of recognition rate. The antecedence neural network can overcome the limitation of boundary decisoion characteristics of nrural network due to the similarity of extracted features. The increased recognition rate is gained by the consequent neural network which is designed to learn inference rules for the effective system output.
