  • There are lipid phase theories and aqueous phase theories among the theories of anesthesia. For water clusters induced by anesthetizing molecules, the interaction energies are calculated using an empirical potential function and correlated with the anesthetizing partial pressures for mice. A good agreement was obtained with the theory that the water clusters around anesthetics play an important role on the anesthetic actions.

  • Purpose: A marketing strategy for private institutions requires marketers to leverage consumer behaviors and educational psychologies when advertising and promoting product portfolios. Indeed, understanding consumers can make marketers more effective, and the purpose of this research is to tackle private institutions' education marketing by combining marketing theories and learning theories. Research design, data and methodology: The content analysis used in this study will be suitable because there exists numerous prior studies regarding marketing strategy and educational theories. Therefore, the current author could obtain and collect adequate textual facts from much of the literature review. Results: Marketing strategies that are mixed with educational theories increase consumer enrolment due to perceived usefulness, and this implies that an adequate marketing model could help improve sustainability and income as a result of enrollment in private educational institutions. The research also identified that marketing is connected to psychology and that marketers can exploit educational and psychological theories to increase successful enrolment in private educational institutions. Conclusions: Most importantly, the target market for private educational institutions is diverse, and institutions can use direct marketing to appeal to specific audiences. Also, the research implies that diversification strategies can increase enrolment if marketers exploit behavioral learning theories in the marketing process.

  • The theories of cultural evolution hold subtly or clearly different stances about definition of culture, pattern of cultural evolution, biases that affect cultural evolution, and relationship between culture and organism. However, the cultural evolution theories have a common problem to solve: As the evolutionary theory of life tries to explain the early steps and the origin of life, the cultural evolution theories also must explain the early steps of the cultural evolution and the role of the human capability that makes cultural evolution possible. Therefore, explanations of the human's unique traits including the cultural ability are related to determine which one is the most plausible among many cultural evolution theories. Theories that tried to explain human uniqueness commonly depict the coevolution of gene (organism) and culture. We will explicitly call the niche construction theory and the dual inheritance theory the 'gene-culture co-evolutionary theory'. In these theories, the most important concept is the 'concept of positive feedback'. In this paper, we distinguish between core positive feedback and marginal positive feedback, according to whether the trait that the concept of positive feedback explains is the trait of human uniqueness. Both types of positive feedback effectively explain the generality of human uniqueness and the diversity of human traits driven by cultural groups. However, this positive feedback requires an end, in contrast to negative feedback which can be continued in order to maintain homeostasis. We argue that the co-evolutionary process in the gene-culture co-evolutionary theories include only the positive feedback, not covering the cultural evolution after the positive feedback. This thesis strives to define the coevolution concept more comprehensively by suggesting the potential relationships between gene and culture after the positive feedback.

  • This literature review was undertaken to explore theoretical models of depression for their potential usefulness in nursing research and practice. Depression has bean accounted for by numerous theories or models of causation ; 11 theories selected from psychology, medicine and psychoanalysis and supported by empirical or experimental research were reviewed. These theories identify a variety of precipitating and predisposing factors that may affect the individual's depression. Aggression - turned - inward theory, object loss theory, ego functioning theory, personality organization theory, behavioral theory, learned helplessness theory, cognitive theory, genetic factors, and biological theories conceptualize predisposing factors. Only life stressors theory identifies precipitating facotrs. Each of these theories contributes to an understanding of depression, but many of them use overlapping and interrelated factors. It is also evident from recent. research that there are multiple causes for depression involving an interactive effect among predisposing and precipitating factors that are both biological and psychological in origin. That is, a single theory is not useful, but perhaps a unified theory could be developed that would be helpful to nursing. This review points to the need for continuing development and testing of theories that would integrate the multiple conceptualizations of depression.

  • A unified mathematical model of phase-lag Green-Naghdi magneto-thermoelasticty theories based on fractional derivative heat transfer for perfectly conducting media in the presence of a constant magnetic field is given. The GN theories as well as the theories of coupled and of generalized magneto-thermoelasticity with thermal relaxation follow as limit cases. The resulting nondimensional coupled equations together with the Laplace transforms techniques are applied to a half space, which is assumed to be traction free and subjected to a thermal shock that is a function of time. The inverse transforms are obtained by using a numerical method based on Fourier expansion techniques. The predictions of the theory are discussed and compared with those for the generalized theory of magneto-thermoelasticity with one relaxation time. The effects of Alfven velocity and the fractional order parameter on copper-like material are discussed in different types of GN theories.

  • The purpose of this study is to analyze what kinds of science education theories are targeted in the "Examination for Appointing Secondary School Science Teachers (EASST)." For the analyses, we extracted the contents related to the science education theories in the question items of the EASST of 2008 through 2012, and categorized those theories into science curriculum, history of science and philosophy of science, scientific inquiry, theory of teaching and learning, model of teaching and learning, and assessment. The results of this study indicated that the theory of teaching and learning appeared most frequently and there were high proportions of question items related to the following topics: contents in science curriculum, scientific method, contemporary philosophy of science, process of inquiry, Ausubel's theory, learning cycle model by Lawson, cooperative learning, criteria of performance assessment, and etc. While we, as science educators, believed that the other categories such as 'history of science' provides important topics for pre-service science teachers, questions items dealing with those were rarely found in the past EASSTs. As EASST has strong influences on the professional developments of pre-service science teachers, more research should be pursued on how much and what domains of science education theories would be appropriate for the test.

  • The purpose of this paper is to find out the present status of public library management. The assumptions on which this research is based are that there are differences between th theories taught at the educational institutions for librarians and the practices actually managed at libraries, and that the differences are greater in Korea than those in the United States of America as the former has a shorter library history and is a more bureaucratic society. The data were collected were collected through the questionnaires sent to fifty-five public library managers in Taegu and Kyungpook province. Forty-two respondents replied, making the returned rate of 76.4%. The results show that there exist some differences between theories and practices, but they are not so great as expected. It was found out that there is a difference between what the theorists state and what the practicing managers accept. It was also found out that the library managers agree that the new management theories and techniques can be adopted to their libraries. The hindering factors are found out, and based on the findings, a few suggestions are provided.

  • Many kinds of teaching methods have been used to instruct ethical issues that arise in the field of science and technology. However, few teaching methods of bioethics have been validated by ethical theories, or justified based on practical utility in bioethics teaching. The aim of this article is to suggest teaching methods of bioethics that are appropriate for ethical theories and socio-scientific issues related to biological sciences in secondary schools. In the article, the teaching methods are classified into three types of ethical theories and into three types of socio-scientific issues in biological sciences. The characteristics of nine teaching/learning methods are then described in terms of appropriate bioethical issues or contexts, and ethical theories or principles.
