Creativity is a trait necessarily demanded in highly industrial and information oriented society. Accordingly, we should develop creativity through school education. The purpose of this study is to inquire a conceptual model and teaching method for developing creative problem solving skills in home economics education which can work at a platform for the curriculum developer. Although many definitions of creativity consider cognitive aspect more, personal or affective aspect is heavily involved with creativity. Therefore, creativity is a dynamic system which cooperates many contrasting and dialectic components in personal and cognitive aspects. The function of creativity is dependent on diverse environmental system. Environments influence on the extent of the development of creativity. Thus, the person-situation interaction model devised by Woodman and Schoenfeldt, integration of cognitive, affective, and situational aspects, is suggested as a conceptual model for teaching creativity in home economics education. The practical reasoning teaching model is suggested as a teaching method for developing creative problem solving skills in home economics education. The components of creative problem solving which involved with practical reasoning process are general knowledge and skills, specific knowledge and skills, divergent thinking skills, motivation and motives, and critical thinking skills.

Embodying the safety of radioactive waste disposal requires the relevant safety criteria and the corresponding stylized methods to demonstrate its compliance with the criteria. This paper proposes a conceptual model of risk-based safety evaluation for integrating complex potential radiation exposure situations in radioactive waste disposal. For demonstrating compliance with a risk constraint, the approach deals with important exposure scenarios from the viewpoint of the receptor to estimate the resulting risk. For respective exposure situations, it considers the occurrence probabilities of the relevant exposure scenarios as their probability of giving rise to doses to estimate the total risk to a representative person by aggregating the respective risks. In this model, an exposure scenario is simply constructed with three components:radionuclide release, radionuclide migration and environment contamination, and interaction between the contaminated media and the receptor. A set of exposure scenarios and the representative person are established from reasonable combinations of the components, based on a balance of their occurrence probabilities and the consequences. In addition, the probability of an exposure scenario is estimated on the assumption that the initiating external factors influence release mechanisms and transport pathways, and its effect on the interaction between the environment and the receptor may be covered in terms of the representative person. This integrated approach enables a systematic risk assessment for complex exposure situations of radioactive waste disposal and facilitates the evaluation of compliance with risk constraints.

Purpose: The study aims to delineate Shariah Governance Framework (SGF) by applying the components of New Institutional Theory (NIT) to provide an understanding of how Islamic banks theoretically influence Shariah Governance (SG) practice, structure, and process. Design/methodology/approach: As it is a conceptual paper, this paper has prepared based on an analytical approach to show how such institutions could provide a more effective system concerning the contents, procedures, and practices for the multiple users in the SG process of Islamic banks. Findings: The paper critically explores the adoption of NIT to develop SGF with its existing practice, structure, and procedure. Utilizing NIT, a proposed theoretical framework has developed for exploring the SG through its major components, i.e., 'isomorphism' and 'legitimacy'. It is stated that NIT can offer a useful framework by which homogenous structures, comprising guidelines, standards, and practices become recognized and authorized as a satisfactory standard corporate exercise. Thus, the proposed theoretical framework would be beneficial in understanding and exploring the SGF. Conclusion: The application of this SGF could help to justify the key dimensions of NIT with its overall formation, function, and practices that might also help to attain legitimacy.

Digital service transformation study is a part of research in the field of digital transformation, which is devoted to exploring the transformations that occur in digital service products, which have been intensely explored in recent years to address digital disruption. Several concepts and definitions of digital service transformation have emerged as a result of an approach from the point of view of digital transformation and digital services concepts. This paper is organized to provide a foundational understanding of digital service transformation terminology. This paper uses the systematic literature review method to compile 52 qualified articles from previous studies. We conduct an analysis and synthesis of articles to answer research questions. The results of this study are a descriptive summary of research in the digital service transformation field, determining digital service transformation terminology and components, and also a proposed digital service transformation model to explain the position of transformation in digital service products in the overall transformation process. We construct this model using the findings of previously determined components synthesis.

In order to effectively promote a smart city, various urban information must be opened and linked, and the information system that each member can share is required. In addition, it is necessary to establish a cooperative system in which citizens and citizen's organizations can participate. In this study, the components and conceptual model of a smart city platform were proposed to create a smart city that enables citizen participation. Its components include sensors for collecting data from the real world, information storage and management, information sharing and standard system, citizens' personal information protection and management system, utilization and service, etc. For the conceptual model, roles of smart city members were defined, so that citizen-centered participation and services could be made. It also includes data collection, information linkage and sharing, and service configuration system. Citizens can perform various roles such as data collector and provider, service planner or requestor, service beneficiary, etc. Ultimately, free communication and exchange of opinions with citizens is a key factor in the success of smart cities.

The objective of this study is to find out the construct of intellectual capital in a fashion company. To this end, the mixed research methods that combined qualitative and quantitative approaches were conducted. Qualitative research was first conducted by in-depth interviews with 16 experts working in the fashion industry, and a questionnaire was then given to 121 fashion companies in order to fulfill the quantitative research portion of this study. The findings of this study are as follows: First, the conceptual structure of intellectual capital in a fashion company was revealed. A fashion company's intellectual capital is composed of 'human capital', 'structural capital', and 'relational capital'. Human capital has three components: a chief executive officer (CEO), members, and a human resource management capability. Structural capital has four components: organizational culture, information management capability, merchandising capability, and product innovation capability. Relational capital has three components: customer equity, marketing capability, and relationship management capability. Second, the conceptual structure of intellectual capital was confirmed via quantitative research analysis. All of the components of intellectual capital have internal consistency, convergent validity, construct validity, and discriminant validity.

In order to build a conceptual design program for a liquid rocket engine system, performance based sub-programs for each core component of the engine system were made. Parts included were the combustion chamber, supersonic nozzle, centrifugal pump, and impulsive turbine. Simple mathematical models based on classical thermodynamic and inviscid theories were adopted with proper tuning by empirical data. In Part I, aiming to validate each sub-program, we examined the results of each program qualitatively, and parametrically investigated the sensitivity due to the change in design parameters.
