In order to help students to understand the essence of prime concepts, this study looked at the history of prime concept development and analyzed how to introduce the concept of textbooks. In ancient Greece, primes were multiplicative atoms. At that time, the unit was not a number, but the development of decimal representations led to the integration of the unit into the number, which raised the issue of primality of 1. Based on the uniqueness of factorization into prime factor, 1 was excluded from the prime, and after that, the concept of prime of the atomic context and the irreducible concept of the divisor context are established. The history of the development of prime concepts clearly reveals that the fact that prime is the multiplicative atom is the essence of the concept. As a result of analyzing the textbooks, the textbook has problems of not introducing the concept essence by introducing the concept of prime into a shaped perspectives or using game, and the problem that the transition to analytic concept definition is radical after the introduction of the concept. Based on the results of the analysis, we have provided several pedagogical implications for helping to focus on a conceptual aspect of prime number.

Purpose: The purpose of this study was to explore the clear concept of organizational commitment for effective nursing personnel management. Method: This study was conducted using Walker & Avant's conceptual analysis framework(2005). Results: Organizational commitment was identified with six attributes: acknowledgment, acceptance, trust, sacrifice, attachment, regulation. Antecedents of organizational commitment were personal characteristics, perceived organizational support, empowerment, fair compensation, job satisfaction, job autonomy, organizational culture, and leadership. Consequences of organizational commitment were turnover intention, job performance and organizational citizenship behavior. Conclusion: Organization commitment is a core concept for understanding the management of nursing personnel. Appropriate instruments to operationalize the concept of organizational commitment including six attributes need to be developed.

Test scenarios can be derived based on some system models for requirements validation purposes. Model-based test suite reduction aims to provide a smaller set of test scenarios which can preserve the original test coverage with respect to some testing criteria. We are proposing to apply Formal Concept Analysis (FCA) in analyzing the association between a set of test scenarios and a set of transitions specified in a state machine model. By utilizing the properties of concept lattice, we are able to determine incrementally a minimal set of test scenarios with adequate test coverage.

Purpose: The purpose of the study was to identify the attributes of rapport, their antecedents and consequences. Methods: Walker and Avant's method for concept analysis was used to analyze the concept. Articles published from January 2007 to May 2017 were searched through PubMed, CINAHL, and RISS databases using "rapport" as a keyword. Results: The attributes of rapport were as follows: 1) understanding; 2) sharing information; 3) empathy; 4) harmonious relationship. The antecedents of rapport were as follows: 1) effective communication skills; 2) relation-oriented attitude. The consequences of rapport were forming trust, therapeutic relationship, improvement of quality of care, increased patients satisfaction and increased nurses satisfaction. Conclusion: Rapport can be defined as a harmonious relationship that understand each other and share ideas and information.

Nursing's traditional concern for human well being includes concern for health promotion. Until recently textbooks of preventive medicine, public health and community health nursing have defined health prevention- the prevention of disease and health protection or maintenace, but not health promotion. Lack of clear definitions inhibit effective communication among health related disciplines. Therefore, this studys task was the analysis and definition of the concept of health promotion using Walker & Avant's concept analysis methodology. This characteristics of the concept of health promotion are 1) orientation toward well - being, 2) empowering, 3) subjectivity, 4) change and 5) expanded connecteness. Antecedent of health promotion are 1) attaining of a healthy state, 2) having purpose and will to act, 3) persistent and realistic behaviour. The consequences of health promotion are 1) prolonged life, 2) self-actualizing potential, 3) increased well-being and a high level quality of life. The future direction of health promotion research should include that identification of the differences in the definition of between health professionals and health clients and research related to nursing theory of health promotion.

A product family design has received much attention over the last several decades, since a product family-based development shortens lead-times and reduces cost, as well as increases efficiency and effectiveness of the product realization process. It is challenging work, however, to define the product family design in the heterogeneous product development environments, due to myriads of products related information described in different ways across products in any companies. In this paper, we provided a way of defining product family design framework using formal concept analysis and ontology language. Based on this, the specific product family can be derived by ontological reasoning, and the new product concept can be also expanded in the framework. The proposed framework is formalized using OWL (Web Ontology Language) and implemented in $Prot{\acute{e}}g{\acute{e}}$. Actual product family design algorithm is carried out using FaCT++ engine, a plug-in to $Prot{\acute{e}}g{\acute{e}}$, and the benefits of the proposed method are also demonstrated through a case study.

Purpose : The purpose of this study is to help understanding nursing application of morale after analysing the concept of morale. Method : With a various investigation of the records on the morale, I identified the characteristics of morale. Result : The characteristics of morale are as follows; 1) The active and voluntary motives of performing in a job. 2) The group phenomena as well as individual ones. 3) The characteristics and changeability according to the situation. 4) The self-esteem and satisfaction in a job. Conclusion : As morale can affect the management and success of organization constantly, the analysis of the concept of morale will be available in nursing administration, so the nursing managers should be interested in morale, And nursing managers should enhance the staff's morale in order that the staffs are willing to participate in their work, to be faithful in an organization, to develop creativity and to do better activities and so they have to contribute to the development of the organization and its members.

In a previous study we proceeded to the remodularization architecture based on classes and packages using the Formal Concept Analysis (FCA)[13] [14] [30]. we then got two possible remodularized architectures and we explored the issue of redistributing classes of a package to other packages, we used an approach based on Oriented Graph to determine the packages that receive the redistributed classes and we evaluated the quality of a remodularized software architecture by metrics [31] [28] [29]. In this paper, we will address the issue of the efficiency of the Oriented Graph in the remodularization of software architectures compared to the Formal Concept Analysis FCA method. The formal method of FCA concept is not popularized among scientists as opposed to the use of the labeled directed graph. It is for this reason that our directed graph approach is more effective in its simplicity and popularity.
