  • This paper presents methodological paradigms : quantitative positivistic (logical empiricism) as the received tradition in the scientific inquiry and qualitative naturalistic (post -positivism or nataralism) as a new paradigm in the Kuhnian sense. Various kind of qualitative methods under the umbrella term, qualitative inquiry, were briefly introduced. Details on the definition, epistemology, naming of subject, field technique (participant observation and ethnographic interview) of ethnographic research method as an adequate method for studying on the unique nursing phenomena in Korean culture were done. Besides, the concept of triangulation, issues on the methododogical paradigm, a criteria for rigor of qualitative naturalistic inquiry were mentioned.

  • 철근콘크리트구조의 연성에 영향을 미치는 중요한 요소인 철근의 최소연신율 규정은 각 나라 규격마다 상이하다. 이는 각 규격마다 철근의 연신율을 산출하는 기준인 표점거리가 다르기 때문이다. 이에 본 연구에서는 각기 다른 표점거리를 가지고 있는 국내외 규격을 비교하고, 단조증가 인장시험을 통하여 어떠한 규격의 연신율 규정이 더 엄격한지에 대해 실험적으로 분석 평가하였다.

  • The purpose of this study is to conceptualize 'proof' school mathematics. We based on the assumption the following. (a) There are several different roles of 'proof' : verification, explanation, systematization, discovery, communication (b) Accepted criteria for the validity and rigor of a mathematical 'proof' is decided by negotiation of school mathematics community. (c) There are dynamic relations between mathematical proof and empirical theory. We need to rethink the nature of mathematical proof and give appropriate consideration to the different types of proof related to the cognitive development of the notion of proof. 'proof' in school mathematics should be conceptualized in the broader, psychological sense of justification rather than in the narrow sense of deductive, formal proof 'proof' has not been taught in elementary mathematics, traditionally, Most students have had little exposure to the ideas of proof before the geometry. However, 'proof' cannot simply be taught in a single unit. Rather, proof must be a consistent part of students' mathematical experience in all grades, in all mathematics.

  • The concept of "set" in school mathematics has undergone many changes according to the revision of curriculum and the transition of the paradigm in mathematics education. In the discipline-centered curriculum, a set was a representative concept which reflected the spirit of New Math. After the Back to Basics period, the significance of a set concept in school mathematics has been diminished. First, this paper elaborated several controversial aspects of the terms related to set, such as a collection and a set, a subset, and an empty set. In addition, the changes of the significance imposed to a set concept in school mathematics were investigated. Finally, this paper provided two alternative approaches to introduce and explain a set concept which emphasized both mathematical rigor and learner's psychology.

  • More a reddish color of KNBP was related to higher frequency of slower fiber type. Tender meat with a faster ageing rate for KNBP was coincided with a faster proteolytic rate, and likely a higher collagen solubility (data not shown). However, it is not confirmed whether the results were linked to the favorable pH/temperature window during rigor development, or fiber composition for tender meat.

  • Purpose: The purpose of this phenomenological study was to explore middle-aged child care providers' experience in caring for children in the community. Methods: The participants were 10 middle-aged child care providers. In-depth interviews were conducted between August and September, 2014 until data. Colaizzi's method of data analysis was applied to inductively determine themes and formulated meanings. Data saturation was achieved and methodological rigor was established Results: Four themes were extracted from 12 meanings. The four themes of the child care providers' experience in caring for children were: 1) weariness from care-giving, 2) the search for one's own solutions, 3) a cheerful attitude to life, 4) the opportunity to start a new life. Conclusion: The results of this study provide useful information for understanding child care providers' experiences in caring for children and establishing effective strategies to support these child care providers.

  • The present study addresses the research frameworks and directions in the area of accounting information systems (AIS) by conducting a comprehensive survey of 76 A/S doctoral dissertations published between 1980 and 1990. The central research task is to identify the distinctive features of A/S that distinguish it from other disciplines. The procedure of the survey analysis is as follows. First, the A/S dissertations are categorized according to information systems (IS) and accounting. Then, some representative A/S research areas are documented, based on the IS/accounting domain combinations. The paper also attempts to discover the topical trends, supporting bases, and qualitative aspects of the A/S research. The survey reveals a : 1) the existence of economics as a supporting discipline, 2) the topical trend consistent with the evolution of IS, but restricted by the specific combinations of its parent domains, and 3) the need for intellectual rigor in the A/S research.

  • Statistical analysis of data is an integral part of research projects in all scientific disciplines including the plant pathology. Appropriate design, application and interpretation of statistical analysis are also, therefore, at the center of publishing and properly evaluating studies in plant pathology. A survey of research works published in the Plant Pathology Journal, however, cast doubt on high standard of statistical analysis required for scientific rigor and reproducibility in the journal. Here I first describe, based on the survey of published works, what mistakes are commonly made and what components are often lacking during statistical analysis and interpretation of its results. Next, I provide possible remedies and suggestions to help guide researchers in preparing manuscript and reviewers in evaluating manuscripts submitted to the Plant Pathology Journal. This is not aiming at delineating technical and practical details of particular statistical methods or approaches.

  • Skeletal muscle metabolism regulates homeostatic balance in animals. The metabolic impact persists even after farm animal skeletal muscle is converted to edible meat through postmortem rigor mortis and aging. Muscle metabolites resulting from animal growth and postmortem storage have a significant impact on meat quality, including flavor and color. Metabolomics studies of postmortem muscle aging have identified metabolisms that contain signatures inherent to muscle properties and the altered metabolites by physiological adaptation, with glycolysis as the pivotal metabolism in postmortem aging. Metabolomics has also played a role in mining relevant postmortem metabolisms and pathways, such as the citrate cycle and mitochondrial metabolism. This leads to a deeper understanding of the mechanisms underlying the generation of key compounds that are associated with meat quality. Genetic background, feeding strategy, and muscle type primarily determine skeletal muscle properties in live animals and affect post-mortem muscle metabolism. With comprehensive metabolite detection, metabolomics is also beneficial for exploring biomarker candidates that could be useful to monitor meat production and predict the quality traits. The present review focuses on advances in farm animal muscle metabolomics, especially postmortem muscle metabolism associated with genetic factors and muscle type.

  • Consumer neuroscience methods have become prevalent in marketing research. Despite their proven significance, very little marketing research has addressed their applications in Asia. Thus, this review aims to introduce practical integrations with consumer neuroscience and marketing research and how they can be carefully applied to these fields, with some identified caveats. Specifically, I review the recent literature from top marketing and science journals to (1) highlight substantial applications of updated neuroscientific methods to marketing research and neuroforecasting approaches, (2) discuss the additional potential of computational models in these applications, and (3) offer a simple framework that adopts a multi-method approach intended to enhance both the external and ecological validity of neuroscientific findings. Along with the need for embracing scientific rigor and marketing theory, more guidelines are also needed to improve the validity issues of neuroimaging uses and highlight practical directions in the nascent field of consumer neuroscience.
