Recently, Evidence-based Medicine (EBM) has been distributed on a worldwide basis, and there is a tendency to scientifically examine the usefulness of medical technology, medicine, preventive medicine, and health politics. This trend is visible not only in the medical field but also throughout the behavioral sciences, including the fields of Nursing and Nutrition. This special issue contains articles on EBM in the fields of Medicine, Nursing, and Nutrition and also includes an article related to Meta-analysis. This paper is an introduction to EBM and presents a discussion of the relationships between EBM and Behaviormetrics.
Evidence-based Medicine (EBM) shows a rapid spread in Medicine and its related fields. The basic view of EBM is being proliferated not only in medicine but also in the field of nursing as well as other medically-related fields. In fact, it is fast becoming the big pillar of medical science. In the present paper, Evidence-based Nursing in Nursing Science is introduced, and the relation between nursing and EBM, the concept of EBN, the Practice of EBN, and the present and future of EBN are discussed through a practice example.
The fundamental process of Evidence-based Nutrition (EBN) is to examine proof by research on human beings. In order to develop EBN, it is important to develop a reliable method for the evaluation of dietary intake and a structured educational procedure based on information of accurate dietary intake. Data analysis based on scientific evidence can accurately produce an evaluation of nutrition education. The development of EBN will bring about the development of human nutrition and nutritional epidemiology. The present paper describes a practical nutrition education study based on EBN.
Meta-analysis is a statistical method which examines all the combinable studies on a particular subject conducted independently in the past in order to estimate the size of the common effect regarding the same research question, e.g., to estimate the efficacy, toxicity effect and environmental risk of certain treatments. In other words, meta-analysis is a scientific procedure that integrates the evidence obtained all over the world. This paper describes its application to clinical research.
This paper proposes a method in which the information system analyzes consumer cognitive characteristics automatically, based on the qualitative information of consumer public information and in which consumer cognitive models are built based on the Internet electronic bulletin board example of the personal computer. The proposed analysis method by which it is possible to build a consumer behavior model is an information system which utilizes a language processing technology. This system can categorize 241 consumers (contributors) into 16 consumer groups. It describes the consumer cognitive models of those groups as quantification models and analyzes the differences among the consumer cognitive characteristics, based on the Internet electronic bulletin board example of the personal computer. An example of an analysis is as follows, “consumer group 1 interests the attributes of information, story and cost, based on communication equipment and electric parts,” and “consumer group 7 interests the attributes of problems, forums, paintings and thinking, based on tools.”
